MuniYield Arizona
Fund, Inc.


Annual Report
October 31, 2004



MuniYield Arizona Fund, Inc. seeks to provide shareholders with as
high a level of current income exempt from federal and Arizona
income taxes as is consistent with its investment policies and
prudent investment management by investing primarily in a portfolio
of long-term, investment grade municipal obligations the interest on
which, in the opinion of bond counsel to the issuer, is exempt from
federal and Arizona income taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield Arizona Fund, Inc. for
their information. It is not a prospectus. Past performance results
shown in this report should not be considered a representation of
future performance. The Fund has leveraged its Common Stock and
intends to remain leveraged by issuing Preferred Stock to provide
the Common Stock shareholders with a potentially higher rate of
return. Leverage creates risks for Common Stock shareholders,
including the likelihood of greater volatility of net asset value
and market price of shares of the Common Stock, and the risk that
fluctuations in the short-term dividend rates of the Preferred Stock
may affect the yield to Common Stock shareholders. Statements and
other information herein are as dated and are subject to change.

MuniYield Arizona Fund, Inc.



The Benefits and Risks of Leveraging


MuniYield Arizona Fund, Inc. utilizes leveraging to seek to enhance
the yield and net asset value of its Common Stock. However, these
objectives cannot be achieved in all interest rate environments. To
leverage, the Fund issues Preferred Stock, which pays dividends at
prevailing short-term interest rates, and invests the proceeds in
long-term municipal bonds. The interest earned on these investments,
net of dividends to Preferred Stock, is paid to Common Stock
shareholders in the form of dividends, and the value of these
portfolio holdings is reflected in the per share net asset value of
the Fund's Common Stock. However, in order to benefit Common Stock
shareholders, the yield curve must be positively sloped; that is,
short-term interest rates must be lower than long-term interest
rates. At the same time, a period of generally declining interest
rates will benefit Common Stock shareholders. If either of these
conditions change, then the risks of leveraging will begin to
outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred
Stock for an additional $50 million, creating a total value of
$150 million available for investment in long-term municipal bonds.
If prevailing short-term interest rates are approximately 3% and
long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the American Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value of
such securities will generally be more volatile than that of fixed-
rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities. As of October 31,
2004, the percentage of the Fund's total net assets invested in
inverse floaters was 13.34%, before the deduction of Preferred
Stock.


Swap Agreements


The Fund may also invest in swap agreements, which are over-the-
counter contracts in which one party agrees to make periodic
payments based on the change in market value of a specified bond,
basket of bonds, or index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a
different bond, basket of bonds or index. Swap agreements may be
used to obtain exposure to a bond or market without owning or taking
physical custody of securities. Swap agreements involve the risk
that the party with whom the Fund has entered into the swap will
default on its obligation to pay the Fund and the risk that the Fund
will not be able to meet its obligations to pay the other party to
the agreement.

A Letter From the President


Dear Shareholder

As we ended the current reporting period, the financial markets were
facing a number of uncertainties. At the top of investors' minds
were questions about economic expansion, corporate earnings,
interest rates and inflation, politics, oil prices and terrorism.

After benefiting from aggressive monetary and fiscal policy
stimulus, some fear the U.S. economy has hit a "soft patch." In
fact, economic expansion has slowed somewhat in recent months, but
we believe it is easing into a pace of growth that is sustainable
and healthy. The favorable economic environment has served to
benefit American corporations, which have continued to post strong
earnings. Although the most impressive results were seen earlier in
the year, solid productivity, improved revenue growth and cost
discipline all point to a vital corporate sector.

In terms of inflation and interest rates, the Federal Reserve Board
(the Fed) has signaled its confidence in the economic recovery by
increasing the Federal Funds target rate four times in the past
several months, from 1% to 2% as of the November 10 Federal Open
Market Committee meeting. Inflation, for its part, has remained in
check. Investors and economists are focused on how quickly Fed
policy will move from here.

With the presidential election now behind us, any politically
provoked market angst should subside to some extent. The effect of
oil prices, however, is more difficult to predict. At around $50 per
barrel, the price of oil is clearly a concern. However, on an
inflation-adjusted basis and considering modern usage levels, the
situation is far from the crisis proportions we saw in the 1980s.
Finally, although terrorism and geopolitical tensions are realities
we are forced to live with today, history has shown us that the
financial effects of any single event tend to be short-lived.

Amid the uncertainty, the Lehman Brothers Municipal Bond Index
posted a 12-month return of +6.03% and a six-month return of
+4.79% as of October 31, 2004. Long-term bond yields were slightly
lower at October 31, 2004 than they were a year earlier. As always,
our investment professionals are closely monitoring the markets,
the economy and the overall environment in an effort to make
well-informed decisions for the portfolios they manage. For the
individual investor, the key during uncertain times is to remain
focused on the big picture. Investment success comes not from
reacting to short-term volatility, but from maintaining a long-term
perspective and adhering to the disciplines of asset allocation,
diversification and rebalancing. We encourage you to work with your
financial advisor to ensure these time-tested techniques are
incorporated into your investment plan.

We thank you for trusting Merrill Lynch Investment Managers with
your investment assets, and we look forward to serving you in the
months and years ahead.



Sincerely,



(Terry K. Glenn)

A Discussion With Your Fund's Portfolio Manager


The Fund was effectively able to enhance yield and preserve net
asset value in a volatile interest rate environment, and ultimately
provided a positive total return for the year.


Describe the recent market environment relative to municipal bonds.

Over the past 12 months, amid considerable monthly volatility, long-
term U.S. Treasury bond yields generally moved lower - despite an
increase in short-term interest rates by the Federal Reserve Board
(the Fed).

As the period began, long-term Treasury yields declined while
their prices, which move in the opposite direction, rose. Somewhat
surprisingly, this increase in bond prices came as the U.S. economy
continued to improve. However, solid job creation remained elusive,
producing a drag on consumer confidence. Against this backdrop,
investors became convinced that the Fed would hold short-term
interest rates near their historic lows, and by mid-March 2004,
yields on 30-year U.S. Treasury bonds had declined to 4.65%.

In early April, however, monthly jobs reports began to show
unexpectedly large gains. Consumer confidence increased, and
investors started to anticipate that the Fed would soon be forced to
raise short-term interest rates to ward off potential inflation.
Yields rose in response, with long-term Treasury bond yields
surpassing 5.50% early in June 2004.

For the rest of the period, bond yields generally fell (and prices
rose) as payroll growth began to wane and inflation appeared
negligible. Although the Fed embarked on a tightening cycle with
a 25 basis point (.25%) interest rate hike in June, it also
telegraphed its intention to continue raising rates at a measured
pace, removing earlier concerns about the potential for more
dramatic increases in the near future. Despite additional Fed
interest rate hikes in August and September, the prospect for a
moderate tightening of monetary policy helped support higher bond
prices, and lower yields, for the remainder of the Fund's fiscal
year. By October 31, 2004, the 30-year Treasury bond yield stood at
4.79%, a decline of 34 basis points from a year earlier. The yield
on the 10-year U.S. Treasury note was 4.02%, a 27 basis point drop
during the same 12-month period.

While tax-exempt bond yields followed the same pattern as their
taxable counterparts, volatility in the municipal market was more
subdued. Yields on long-term revenue bonds, as measured by the
Bond Buyer Revenue Bond Index, fell 27 basis points during the past
12 months. According to Municipal Market Data, yields on AAA-rated
issues maturing in 30 years declined 22 basis points to 4.60%, while
yields on 10-year AAA-rated issues dropped 28 basis points to 3.40%.

The tax-exempt market was supported by generally positive supply/
demand dynamics. While more than $360 billion in new long-term tax-
exempt bonds was issued in the past 12 months, this represented a
decline of approximately 6% compared to the previous year. The
declining supply amid favorable demand allowed tax-exempt bond
prices to perform in line with the taxable market.


Describe conditions in the State of Arizona during the period.

Economic indicators for the State of Arizona continue to show signs
of improvement. State general fund collections continued to come in
above forecast and well above year-ago levels. Sales tax collections
also have been strong, and indicate diversified growth in the
economy. Further confirmation of improving economic conditions is
the state's unemployment rate, which has remained relatively low
compared to national levels. In recognition of positive developments
in the state, ratings agency Standard & Poor's (S&P) recently
revised its outlook on Arizona's lease-back debt from negative to
stable. S&P also affirmed the state's AA- rating.


How did the Fund perform during the fiscal year in light of the
existing market conditions?

For the 12-month period ended October 31, 2004, the Common Stock of
MuniYield Arizona Fund, Inc. had net annualized yields of 6.12% and
6.09%, based on a year-end per share net asset value of $15.04 and a
per share market price of $15.10, respectively, and $.92 per share
income dividends. Over the same period, the total investment return
on the Fund's Common Stock was +9.40%, based on a change in per
share net asset value from $14.64 to $15.04, and assuming
reinvestment of ordinary income dividends.



MUNIYIELD ARIZONA FUND, INC., OCTOBER 31, 2004



We were positioned for rising interest rates, while long-term rates
actually declined modestly over the past year. Nevertheless, the
Fund provided a positive total return for the fiscal year. The
strong total return is attributed to the Fund's above-average yield,
which also allowed us to increase the monthly dividend paid to
shareholders, and to the advance refunding of a sizeable credit in
the portfolio. When municipal bonds are advance refunded, or
refinanced ahead of their maturity date, their prices generally
increase sharply, particularly when the yield curve is relatively
steep. Offsetting these positive factors was the extraordinary
redemption of several bonds in the portfolio ahead of their maturity
dates, which had a negative price impact on these holdings.

For the six-month period ended October 31, 2004, the total
investment return on the Fund's Common Stock was +7.47%, based on a
change in per share net asset value from $14.45 to $15.04, and
assuming reinvestment of ordinary income dividends.

For a description of the Fund's total investment return based on a
change in the per share market value of the Fund's Common Stock (as
measured by the trading price of the Fund's shares on the American
Stock Exchange), and assuming reinvestment of dividends, please
refer to the Financial Highlights section of this report. As a
closed-end fund, the Fund's shares may trade in the secondary market
at a premium or discount to the Fund's net asset value. As a result,
total investment returns based on changes in the market value of the
Fund's Common Stock can vary significantly from total investment
returns based on changes in the Fund's net asset value.


What changes were made to the portfolio during the year?

We did not significantly alter the Fund's structure or our
investment strategy over the past 12 months. In general, the Fund is
positioned as we would like, and our approach has been more a matter
of maintenance and refinement.

We continued to selectively purchase higher-yielding credits in
an effort to enhance the Fund's yield. We also continued to
favor premium-coupon bonds, when available, and maturities in the 20-
year - 25-year range. The municipal yield curve flattened out past
this range; therefore, there was no significant yield to be gained
by extending further out.

We purchased Puerto Rico-issued municipal debt as opportunities
presented themselves. Supply in this area was relatively heavy in
early summer, and the issues coming to market had the coupon and
maturity characteristics we were seeking. Supply of new Arizona
debt, while fairly regular, offered fewer bonds with the attributes
we desired.

Finally, we maintained the Fund's fully invested position throughout
the year, seeking to enhance shareholder income. With short-term
interest rates still near historic lows, the cost of holding cash
reserves would have been relatively high in terms of its impact on
performance.

For the six-month period ended October 31, 2004, the Fund's Auction
Market Preferred Stock (AMPS) had an average yield of 1.02% for
Series A and 1.08% for Series B. These attractive funding levels, in
combination with a positively sloped yield curve, continued to
provide a generous income benefit to the Common Stock shareholder
from the leveraging of Preferred Stock. While the Fed is likely to
continue raising short-term interest rates, the increases are
expected to be gradual and should not have an immediate material
impact on the positive advantage leverage has had on the Fund's
Common Stock yield. However, should the spread between short-term
and long-term interest rates narrow, the benefits of leveraging will
decline and, as a result, reduce the yield on the Fund's Common
Stock. At the end of the period, the Fund's leverage amount, due to
AMPS, was 31.12% of total net assets. (For a more complete
explanation of the benefits and risks of leveraging, see page 2 of
this report to shareholders.)


How would you characterize the Fund's position at the close of the
period?

We remain overweight in premium-coupon bonds and continue to favor
maturities in the 25-year range. We maintained our defensive market
posture at the close of the period in recognition of improving
economic conditions, including stronger, albeit still inconsistent,
employment growth. We believe this positioning prepares the Fund for
relative outperformance once interest rates inevitably begin to
rise. With the Fed expected to continue its monetary tightening
policy, long-term market rates should eventually begin to follow
short-term interest rates higher. (In fact, the Fed increased its
target interest rate another 25 basis points shortly after the close
of the reporting period, on November 10.) In the meantime, our fully
invested stance should continue to provide a material benefit to
Common Stock shareholders as short-term interest rates remain
relatively low.

Notes to Financial Statements


1. Significant Accounting Policies:
MuniYield Arizona Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as amended, as a non-diversified,
closed-end management investment company. The Fund's financial
statements are prepared in conformity with U.S. generally accepted
accounting principles, which may require the use of management
accruals and estimates. Actual results may differ from these
estimates. The Fund determines and makes available for publication
the net asset value of its Common Stock on a weekly basis. The
Fund's Common Stock is listed on the American Stock Exchange under
the symbol MZA. The following is a summary of significant accounting
policies followed by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the last available
bid price in the over-the-counter market or on the basis of values
as obtained by a pricing service. Pricing services use valuation
matrixes that incorporate both dealer-supplied valuations and
valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general direction of the Board of Directors. Such valuations and
procedures will be reviewed periodically by the Board of Directors
of the Fund. Financial futures contracts and options thereon, which
are traded on exchanges, are valued at their closing prices as of
the close of such exchanges. Options written or purchased are valued
at the last sale price in the case of exchange-traded options. In
the case of options traded in the over-the-counter market, valuation
is the last asked price (options written) or the last bid price
(options purchased). Swap agreements are valued by quoted fair
values received daily by the Fund's pricing service. Short-term
investments with a remaining maturity of 60 days or less are valued
at amortized cost, which approximates market value, under which
method the investment is valued at cost and any premium or discount
is amortized on a straight line basis to maturity. Investments in
open-end investment companies are valued at their net asset value
each business day. Securities and assets for which market quotations
are not readily available are valued at fair value as determined in
good faith by or under the direction of the Board of Directors of
the Fund.

(b) Derivative financial instruments--The Fund may engage in various
portfolio investment strategies both to increase the return of the
Fund and to hedge, or protect, its exposure to interest rate
movements and movements in the securities markets. Losses may arise
due to changes in the value of the contract or if the counterparty
does not perform under the contract.

* Financial futures contracts--The Fund may purchase or sell
financial futures contracts and options on such futures contracts.
Futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which
the transaction is effected. Pursuant to the contract, the Fund
agrees to receive from or pay to the broker an amount of cash equal
to the daily fluctuation in value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Fund
as unrealized gains or losses. When the contract is closed, the Fund
records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value at the
time it was closed.

* Options--The Fund may write covered call options and purchase
put options. When the Fund writes an option, an amount equal to
the premium received by the Fund is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the current market value of the option
written. When a security is purchased or sold through an exercise of
an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option
expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.



MUNIYIELD ARIZONA FUND, INC., OCTOBER 31, 2004



Notes to Financial Statements (continued)


* Forward interest rate swaps--The Fund may enter into forward
interest rate swaps. In a forward interest rate swap, the Fund and
the counterparty agree to make periodic net payments on a specified
notional contract amount, commencing on a specified future effective
date, unless terminated earlier. When the agreement is closed, the
Fund records a realized gain or loss in an amount equal to the value
of the agreement.

(c) Income taxes--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute substantially all of its
taxable income to its shareholders. Therefore, no federal income tax
provision is required.

(d) Security transactions and investment income--Security
transactions are recorded on the dates the transactions are entered
into (the trade dates). Realized gains and losses on security
transactions are determined on the identified cost basis. Dividend
income is recorded on the ex-dividend dates. Interest income is
recognized on the accrual basis. The Fund amortizes all premiums and
discounts on debt securities.

(e) Dividends and distributions--Dividends from net investment
income are declared and paid monthly. Distributions of capital gains
are recorded on the ex-dividend dates.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is
Princeton Services, Inc. ("PSI"), an indirect, wholly-owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the
limited partner.

FAM is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain
other services necessary to the operations of the Fund. For such
services, the Fund pays a monthly fee at an annual rate of .50% of
the Fund's average weekly net assets, including proceeds from the
issuance of Preferred Stock. The Investment Adviser has agreed to
reimburse its management fee by the amount of management fees the
Fund pays to FAM indirectly through its investment in CMA Arizona
Municipal Money Fund. For the year ended October 31, 2004, FAM
reimbursed the Fund in the amount of $10,106.

For the year ended October 31, 2004, the Fund reimbursed FAM $2,808
for certain accounting services.

Certain officers and/or directors of the Fund are officers and/or
directors of FAM, PSI, and/or ML & Co.


3. Investments:
Purchases and sales of investments, excluding short-term securities,
for the year ended October 31, 2004 were $22,656,411 and
$22,069,407, respectively.


4. Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of stock
without approval of holders of Common Stock.

Common Stock
Shares issued and outstanding during the years ended October 31,
2004 and October 31, 2003 increased by 14,166 and 2,294,
respectively, as a result of dividend reinvestment.

Preferred Stock
Auction Market Preferred Stock are redeemable shares of Preferred
Stock of the Fund, with a par value of $.10 per share and a
liquidation preference of $25,000 per share, plus accrued and unpaid
dividends, that entitle their holders to receive cash dividends at
an annual rate that may vary for the successive dividend periods.
The yields in effect at October 31, 2004 were as follows: Series A,
1.10% and Series B, 1.40%.

The Fund pays commissions to certain broker-dealers at the
end of each auction at an annual rate ranging from .25% to
.375%, calculated on the proceeds of each auction. For the year
ended October 31, 2004, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, an affiliate of FAM, earned $19,151 as commissions.



MUNIYIELD ARIZONA FUND, INC., OCTOBER 31, 2004



Notes to Financial Statements (concluded)


5. Distributions to Shareholders:
The Fund paid a tax-exempt income dividend to holders of Common
Stock in the amount of $.077000 per share on November 29, 2004 to
shareholders of record on November 12, 2004.

The tax character of distributions paid during the fiscal years
ended October 31, 2004 and October 31, 2003 was as follows:


                                      10/31/2004         10/31/2003

Distributions paid from:
   Tax-exempt income             $     4,374,684    $     4,189,068
                                 ---------------    ---------------
Total distributions              $     4,374,684    $     4,189,068
                                 ===============    ===============


As of October 31, 2004, the components of accumulated earnings on a
tax basis were as follows:


Undistributed tax-exempt income--net                $     1,196,408
Undistributed ordinary income--net                            3,295
Undistributed long-term capital gains--net                  101,391
                                                    ---------------
Total undistributed earnings--net                         1,301,094

                                                    ===============

* The difference between book-basis and tax-basis net unrealized
  gains is attributable primarily to the tax deferral of losses on
  wash sales and the tax deferral of losses on straddles.

Automatic Dividend Reinvestment Plan (unaudited)


The following description of the Fund's Automatic Dividend
Reinvestment Plan (the "Plan") is sent to you annually as required
by federal securities laws.

Pursuant to the Fund's Plan, unless a holder of Common Stock
otherwise elects, all dividend and capital gains distributions
will be automatically reinvested by The Bank of New York (the
"Plan Agent"), as agent for shareholders in administering the
Plan, in additional shares of Common Stock of the Fund. Holders
of Common Stock who elect not to participate in the Plan will
receive all distributions in cash paid by check mailed directly
to the shareholder of record (or, if the shares are held in street
or other nominee name then to such nominee) by The Bank of New
York, as dividend paying agent. Such participants may elect not
to participate in the Plan and to receive all distributions of
dividends and capital gains in cash by sending written instructions
to The Bank of New York, as dividend paying agent, at the address
set forth below. Participation in the Plan is completely voluntary
and may be terminated or resumed at any time without penalty by
written notice if received by the Plan Agent not less than ten days
prior to any dividend record date; otherwise such termination will
be effective with respect to any subsequently declared dividend or
distribution.

Whenever the Fund declares an income dividend or capital gains
distribution (collectively referred to as "dividends") payable
either in shares or in cash, non-participants in the Plan will
receive cash and participants in the Plan will receive the
equivalent in shares of Common Stock. The shares will be acquired
by the Plan Agent for the participant's account, depending upon
the circumstances described below, either (i) through receipt of
additional unissued but authorized shares of Common Stock from
the Fund ("newly issued shares") or (ii) by purchase of outstanding
shares of Common Stock on the open market ("open-market purchases")
on the American Stock Exchange or elsewhere. If on the payment date
for the dividend, the net asset value per share of the Common Stock
is equal to or less than the market price per share of the Common
Stock plus estimated brokerage commissions (such conditions being
referred to herein as "market premium"), the Plan Agent will invest
the dividend amount in newly issued shares on behalf of the
participant. The number of newly issued shares of Common Stock to be
credited to the participant's account will be determined by dividing
the dollar amount of the dividend by the net asset value per share
on the date the shares are issued, provided that the maximum
discount from the then current market price per share on the date of
issuance may not exceed 5%. If, on the dividend payment date, the
net asset value per share is greater than the market value (such
condition being referred to herein as "market discount"), the Plan
Agent will invest the dividend amount in shares acquired on behalf
of the participant in open-market purchases.

In the event of a market discount on the dividend payment date, the
Plan Agent will have until the last business day before the next
date on which the shares trade on an "ex-dividend" basis or in no
event more than 30 days after the dividend payment date (the "last
purchase date") to invest the dividend amount in shares acquired in
open-market purchases. It is contemplated that the Fund will pay
monthly income dividends. Therefore, the period during which open-
market purchases can be made will exist only from the payment date
on the dividend through the date before the next "ex-dividend" date,
which typically will be approximately ten days. If, before the Plan
Agent has completed its open-market purchases, the market price of a
share of Common Stock exceeds the net asset value per share, the
average per share purchase price paid by the Plan Agent may exceed
the net asset value of the Fund's shares, resulting in the
acquisitions of fewer shares than if the dividend had been paid in
newly issued shares on the dividend payment date. Because of the
foregoing difficulty with respect to open-market purchases, the Plan
provides that if the Plan Agent is unable to invest the full
dividend amount in open-market purchases during the purchase period
or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market
purchases and will invest the uninvested portion of the dividend
amount in newly issued shares at the close of business on the last
purchase date determined by dividing the uninvested portion of the
dividend by the net asset value per share.



MUNIYIELD ARIZONA FUND, INC., OCTOBER 31, 2004



The Plan Agent maintains all shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account,
including information needed by shareholders for tax records. Shares
in the account of each Plan participant will be held by the Plan
Agent in non-certificated form in the name of the participant, and
each shareholder's proxy will include those shares purchased or
received pursuant to the Plan. The Plan Agent will forward all proxy
solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.

In the case of shareholders such as banks, brokers or nominees
which hold shares of others who are the beneficial owners, the
Plan Agent will administer the Plan on the basis of the number of
shares certified from time to time by the record shareholders as
representing the total amount registered in the record shareholder's
name and held for the account of beneficial owners who are to
participate in the Plan.

There will be no brokerage charges with respect to shares issued
directly by the Fund as a result of dividends or capital gains
distributions payable either in shares or in cash. However, each
participant will pay a pro rata share of brokerage commissions
incurred with respect to the Plan Agent's open-market purchases in
connection with the reinvestment of dividends.

The automatic reinvestment of dividends and distributions will not
relieve participants of any federal, state or local income tax that
may be payable (or required to be withheld) on such dividends.

Shareholders participating in the Plan may receive benefits not
available to shareholders not participating in the Plan. If the
market price plus commissions of the Fund's shares is above the
net asset value, participants in the Plan will receive shares of
the Fund at less than they could otherwise purchase them and will
have shares with a cash value greater than the value of any cash
distribution they would have received on their shares. If the market
price plus commissions is below the net asset value, participants
will receive distributions in shares with a net asset value greater
than the value of any cash distribution they would have received on
their shares. However, there may be insufficient shares available in
the market to make distributions in shares at prices below the net
asset value. Also, since the Fund does not redeem shares, the price
on resale may be more or less than the net asset value.

The value of shares acquired pursuant to the Plan will generally be
excluded from gross income to the extent that the cash amount
reinvested would be excluded from gross income. If, when the Fund's
shares are trading at a premium over net asset value, the Fund
issues shares pursuant to the Plan that have a greater fair market
value than the amount of cash reinvested, it is possible that all or
a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable
distribution. If the discount is viewed as a taxable distribution,
it is also possible that the taxable character of this discount
would be allocable to all the shareholders, including shareholders
who do not participate in the Plan. Thus, shareholders who do not
participate in the Plan might be required to report as ordinary
income a portion of their distributions equal to their allocable
share of the discount.

Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the
Plan. There is no direct service charge to participants in the Plan;
however, the Fund reserves the right to amend the Plan to include a
service charge payable by the participants.

All correspondence concerning the Plan should be directed to the
Plan Agent at The Bank of New York, Church Street Station, P.O. Box
11258, New York, NY 10286-1258, Telephone: 800-432-8224.

Availability of Quarterly Schedule of Investments


The Fund files its complete schedule of portfolio holdings with the

quarters of each fiscal year on Form N-Q. The Fund's Forms N-Q are
available on the SEC's Web site at http://www.sec.gov. The Fund's

Dividend Policy


The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more stable level of dividend
distributions, the Fund may at times pay out less than the entire
amount of net investment income earned in any particular month and
may at times in any particular month pay out such accumulated but
undistributed income in addition to net investment income earned in
that month. As a result, the dividends paid by the Fund for any
particular month may be more or less than the amount of net
investment income earned by the Fund during such month. The Fund's
current accumulated but undistributed net investment income, if any,
is disclosed in the Statement of Net Assets, which comprises part of
the financial information included in this report.

is available without charge upon request by calling toll-free
1-800-MER-FUND (1-800-637-3863).

Item 3 - Audit Committee Financial Expert - The registrant's board
of directors has determined that (i) the registrant has the

independent: (1) Joe Grills, (2) Andre F. Perold (resigned as of
October 1, 2004), (3) Robert S. Salomon, Jr., and (4) Stephen B.

(e)(1) The registrant's audit committee (the "Committee") has
adopted policies and procedures with regard to the pre-approval of

by the Committee.  The Committee also must approve other non-audit
services provided to the registrant and those non-audit services
provided to the registrant's affiliated service providers that
relate directly to the operations and the financial reporting of the
registrant.  Certain of these non-audit services that the Committee
believes are a) consistent with the SEC's auditor independence rules
and b) routine and recurring services that will not impair the
independence of the independent accountants may be approved by the
Committee without consideration on a specific case-by-case basis
("general pre-approval").  However, such services will only be
deemed pre-approved provided that any individual project does not
exceed $5,000 attributable to the registrant or $50,000 for all of
the registrants the Committee oversees.  Any proposed services
exceeding the pre-approved cost levels will require specific pre-
approval by the Committee, as will any other services not subject to
general pre-approval (e.g., unanticipated but permissible services).
The Committee is informed of each service approved subject to
general pre-approval at the next regularly scheduled in-person board
meeting.

controlled by, or under common control with the investment adviser
that provides ongoing services to the registrant that were not pre-
approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation

Item 6 - Schedule of Investments - Not Applicable

Item 7 - Disclosure of Proxy Voting Policies and Procedures for
Closed-End Management Investment Companies -

Proxy Voting Policies and Procedures

Each Fund's Board of Directors/Trustees has delegated to Merrill
Lynch Investment Managers, L.P. and/or Fund Asset Management, L.P.
(the "Investment Adviser") authority to vote all proxies relating to
the Fund's portfolio securities.  The Investment Adviser has adopted
policies and procedures ("Proxy Voting Procedures") with respect to
the voting of proxies related to the portfolio securities held in
the account of one or more of its clients, including a Fund.
Pursuant to these Proxy Voting Procedures, the Investment Adviser's
primary objective when voting proxies is to make proxy voting
decisions solely in the best interests of each Fund and its
shareholders, and to act in a manner that the Investment Adviser
believes is most likely to enhance the economic value of the
securities held by the Fund.  The Proxy Voting Procedures are
designed to ensure that that the Investment Adviser considers the
interests of its clients, including the Funds, and not the interests
of the Investment Adviser, when voting proxies and that real (or
perceived) material conflicts that may arise between the Investment
Adviser's interest and those of the Investment Adviser's clients are
properly addressed and resolved.

In order to implement the Proxy Voting Procedures, the Investment
Adviser has formed a Proxy Voting Committee (the "Committee").  The
Committee is comprised of the Investment Adviser's Chief Investment
Officer (the "CIO"), one or more other senior investment
professionals appointed by the CIO, portfolio managers and
investment analysts appointed by the CIO and any other personnel the
CIO deems appropriate.  The Committee will also include two non-
voting representatives from the Investment Adviser's Legal
department appointed by the Investment Adviser's General Counsel.
The Committee's membership shall be limited to full-time employees
of the Investment Adviser.  No person with any investment banking,
trading, retail brokerage or research responsibilities for the
Investment Adviser's affiliates may serve as a member of the
Committee or participate in its decision making (except to the
extent such person is asked by the Committee to present information
to the Committee, on the same basis as other interested
knowledgeable parties not affiliated with the Investment Adviser
might be asked to do so).  The Committee determines how to vote the
proxies of all clients, including a Fund, that have delegated proxy
voting authority to the Investment Adviser and seeks to ensure that
all votes are consistent with the best interests of those clients
and are free from unwarranted and inappropriate influences.  The
Committee establishes general proxy voting policies for the
Investment Adviser and is responsible for determining how those
policies are applied to specific proxy votes, in light of each
issuer's unique structure, management, strategic options and, in
certain circumstances, probable economic and other anticipated
consequences of alternate actions.  In so doing, the Committee may
determine to vote a particular proxy in a manner contrary to its
generally stated policies.  In addition, the Committee will be
responsible for ensuring that all reporting and recordkeeping
requirements related to proxy voting are fulfilled.

The Committee may determine that the subject matter of a recurring
proxy issue is not suitable for general voting policies and requires
a case-by-case determination.  In such cases, the Committee may
elect not to adopt a specific voting policy applicable to that
issue.  The Investment Adviser believes that certain proxy voting
issues require investment analysis - such as approval of mergers and
other significant corporate transactions - akin to investment
decisions, and are, therefore, not suitable for general guidelines.
The Committee may elect to adopt a common position for the
Investment Adviser on certain proxy votes that are akin to
investment decisions, or determine to permit the portfolio manager
to make individual decisions on how best to maximize economic value
for a Fund (similar to normal buy/sell investment decisions made by
such portfolio managers).  While it is expected that the Investment
Adviser will generally seek to vote proxies over which the
Investment Adviser exercises voting authority in a uniform manner
for all the Investment Adviser's clients, the Committee, in
conjunction with a Fund's portfolio manager, may determine that the
Fund's specific circumstances require that its proxies be voted
differently.

To assist the Investment Adviser in voting proxies, the Committee
has retained Institutional Shareholder Services ("ISS").  ISS is an
independent adviser that specializes in providing a variety of
fiduciary-level proxy-related services to institutional investment
managers, plan sponsors, custodians, consultants, and other
institutional investors.  The services provided to the Investment
Adviser by ISS include in-depth research, voting recommendations
(although the Investment Adviser is not obligated to follow such
recommendations), vote execution, and recordkeeping.  ISS will also
assist the Fund in fulfilling its reporting and recordkeeping
obligations under the Investment Company Act.

The Investment Adviser's Proxy Voting Procedures also address
special circumstances that can arise in connection with proxy
voting.  For instance, under the Proxy Voting Procedures, the
Investment Adviser generally will not seek to vote proxies related
to portfolio securities that are on loan, although it may do so
under certain circumstances.  In addition, the Investment Adviser
will vote proxies related to securities of foreign issuers only on a
best efforts basis and may elect not to vote at all in certain
countries where the Committee determines that the costs associated
with voting generally outweigh the benefits.  The Committee may at
any time override these general policies if it determines that such
action is in the best interests of a Fund.

From time to time, the Investment Adviser may be required to vote
proxies in respect of an issuer where an affiliate of the Investment
Adviser (each, an "Affiliate"), or a money management or other
client of the Investment Adviser (each, a "Client") is involved.
The Proxy Voting Procedures and the Investment Adviser's adherence
to those procedures are designed to address such conflicts of
interest.  The Committee intends to strictly adhere to the Proxy
Voting Procedures in all proxy matters, including matters involving
Affiliates and Clients.  If, however, an issue representing a non-
routine matter that is material to an Affiliate or a widely known
Client is involved such that the Committee does not reasonably
believe it is able to follow its guidelines (or if the particular
proxy matter is not addressed by the guidelines) and vote
impartially, the Committee may, in its discretion for the purposes
of ensuring that an independent determination is reached, retain an
independent fiduciary to advise the Committee on how to vote or to
cast votes on behalf of the Investment Adviser's clients.

In the event that the Committee determines not to retain an
independent fiduciary, or it does not follow the advice of such an
independent fiduciary, the powers of the Committee shall pass to a
subcommittee, appointed by the CIO (with advice from the Secretary
of the Committee), consisting solely of Committee members selected
by the CIO.  The CIO shall appoint to the subcommittee, where
appropriate, only persons whose job responsibilities do not include
contact with the Client and whose job evaluations would not be
affected by the Investment Adviser's relationship with the Client
(or failure to retain such relationship).  The subcommittee shall
determine whether and how to vote all proxies on behalf of the
Investment Adviser's clients or, if the proxy matter is, in their
judgment, akin to an investment decision, to defer to the applicable
portfolio managers, provided that, if the subcommittee determines to
alter the Investment Adviser's normal voting guidelines or, on
matters where the Investment Adviser's policy is case-by-case, does
not follow the voting recommendation of any proxy voting service or
other independent fiduciary that may be retained to provide research
or advice to the Investment Adviser on that matter, no proxies
relating to the Client may be voted unless the Secretary, or in the
Secretary's absence, the Assistant Secretary of the Committee
concurs that the subcommittee's determination is consistent with the
Investment Adviser's fiduciary duties

In addition to the general principles outlined above, the Investment
Adviser has adopted voting guidelines with respect to certain
recurring proxy issues that are not expected to involve unusual
circumstances.  These policies are guidelines only, and the
Investment Adviser may elect to vote differently from the
recommendation set forth in a voting guideline if the Committee
determines that it is in a Fund's best interest to do so.  In
addition, the guidelines may be reviewed at any time upon the
request of a Committee member and may be amended or deleted upon the
vote of a majority of Committee members present at a Committee
meeting at which there is a quorum.

The Investment Adviser has adopted specific voting guidelines with
respect to the following proxy issues:

* Proposals related to the composition of the Board of Directors of
issuers other than investment companies.  As a general matter, the
Committee believes that a company's Board of Directors (rather than
shareholders) is most likely to have access to important, nonpublic
information regarding a company's business and prospects, and is
therefore best-positioned to set corporate policy and oversee
management.  The Committee, therefore, believes that the foundation
of good corporate governance is the election of qualified,
independent corporate directors who are likely to diligently
represent the interests of shareholders and oversee management of
the corporation in a manner that will seek to maximize shareholder
value over time.  In individual cases, the Committee may look at a
nominee's history of representing shareholder interests as a
director of other companies or other factors, to the extent the
Committee deems relevant.

* Proposals related to the selection of an issuer's independent
auditors.  As a general matter, the Committee believes that
corporate auditors have a responsibility to represent the interests
of shareholders and provide an independent view on the propriety of
financial reporting decisions of corporate management.  While the
Committee will generally defer to a corporation's choice of auditor,
in individual cases, the Committee may look at an auditors' history
of representing shareholder interests as auditor of other companies,
to the extent the Committee deems relevant.

* Proposals related to management compensation and employee
benefits.  As a general matter, the Committee favors disclosure of
an issuer's compensation and benefit policies and opposes excessive
compensation, but believes that compensation matters are normally
best determined by an issuer's board of directors, rather than
shareholders.  Proposals to "micro-manage" an issuer's compensation
practices or to set arbitrary restrictions on compensation or
benefits will, therefore, generally not be supported.

* Proposals related to requests, principally from management, for
approval of amendments that would alter an issuer's capital
structure.  As a general matter, the Committee will support requests
that enhance the rights of common shareholders and oppose requests
that appear to be unreasonably dilutive.

* Proposals related to requests for approval of amendments to an
issuer's charter or by-laws.  As a general matter, the Committee
opposes poison pill provisions.

* Routine proposals related to requests regarding the formalities of
corporate meetings.

* Proposals related to proxy issues associated solely with holdings
of investment company shares.  As with other types of companies, the
Committee believes that a fund's Board of Directors (rather than its
shareholders) is best-positioned to set fund policy and oversee
management.  However, the Committee opposes granting Boards of
Directors authority over certain matters, such as changes to a
fund's investment objective, that the Investment Company Act
envisions will be approved directly by shareholders.

* Proposals related to limiting corporate conduct in some manner
that relates to the shareholder's environmental or social concerns.
The Committee generally believes that annual shareholder meetings
are inappropriate forums for discussion of larger social issues, and
opposes shareholder resolutions "micromanaging" corporate conduct or
requesting release of information that would not help a shareholder
evaluate an investment in the corporation as an economic matter.
While the Committee is generally supportive of proposals to require
corporate disclosure of matters that seem relevant and material to
the economic interests of shareholders, the Committee is generally
not supportive of proposals to require disclosure of corporate
matters for other purposes.
