The Municipal Market Environment
Municipal bond yields rose dramatically over the six-month period
ended July 31, 1996. Investors became increasingly alarmed that
earlier forecasts of continued moderate growth were overly
optimistic. As indications of stronger growth were released,
particularly the strong employment reports released beginning in
March, fears of associated inflationary pressures mounted and yield
rose in response. By May and June, long-term municipal bond yields
rose into the 6.25%--6.30% range.

However, in early July the combination of the Federal Reserve Board
suggesting that growth was expected to slow later in 1996 and a
temporary stock market correction allowed municipal bond yields to
fall as investors scrambled to purchase relatively scarce
securities. As measured by the Bond Buyer Revenue Bond Index, long-
term, A-rated uninsured tax-exempt bonds yielded 6.02% at July 31,
1996, an increase of over 30 basis points (0.30%) in the last six
months. Long-term US Treasury bond yields rose significantly higher
over the same period. By July 31, 1996, yields on US Treasury bonds
increased almost 100 basis points to end the six-month period at
6.97%.

The municipal bond market's recent outperformance as compared to its
taxable counterpart was largely the result of two principal factors.
First, much of the concern in the tax-exempt market regarding the
potential loss of the inherent tax-advantage of the municipal bonds
dissipated. For much of 1995, various tax proposals, such as the
flat-tax or national sales tax, were put forward either to reduce
the national debt or reform the current tax system. Most of these
proposals would have severely limited the tax advantages enjoyed by
the municipal bond market. However, in February 1996, the Kemp
Commission released its findings regarding various tax reform
proposals. While noting that numerous changes should be made, no
mention of curtailing or stopping municipal bonds' current favored
tax status was made.

The second major factor leading to the municipal bond market's
recent outperformance was the return of a more favorable technical
environment. The rate of increase in new bond issuance recently
slowed. Over the last 12 months, approximately $175 billion in long-
term municipal securities were issued, an increase of over 27% as
compared to the same period a year earlier. Much of this increase
was the result of issuers seeking to refinance their existing higher-
couponed debt as interest rates declined in 1995 and early 1996. As
interest rates rose, these financings became increasingly
economically impractical and issuance declined. Over the last six
months, less than $70 billion in long-term tax-exempt securities
were underwritten, an increase of 20% versus the comparable period a
year earlier. Only $43 billion in tax-exempt securities were issued
in the last three months, a total essentially unchanged from the
comparable quarter in 1995. In July 1996, less than $10 billion in
long-term municipal bonds were issued, representing the lowest
issuance for the month of July since 1990.
<PAGE>
At the same time investor demand remained consistently strong. With
nominal new issue yields above 6%, retail investor interest was
steady. Additionally, investors received over $50 billion this June
and July in assets derived from coupon income, bond maturities, and
proceeds from early redemptions. Annual new bond issuance has
declined in recent years and is expected to remain below levels seen
in the early 1990s. Consequently, as the higher-coupon bonds issued
in the early-to-mid 1980s were redeemed at their first optional call
dates, the total number of outstanding tax-exempt bonds has
declined. This combination of a declining net supply and significant
amounts of assets helped maintain investor demand in recent months.

It is unlikely that the municipal bond market will continue to
significantly outperform US Treasury securities in the near future.
The tax-exempt bond market's recent performance led to the yield
ratio between long-term taxable and tax-exempt securities falling
from in excess of 90% to approximately 85%. While still historically
very attractive, some institutional investors, particularly short-
term traders, began to view the tax-exempt bond market's recent
outperformance as an opportunity to sell a relatively expensive
asset. However, to the long-term investor, such a sale would
represent the loss of an attractively priced asset which may not be
easily replaced given the relative scarcity of municipal bonds under
present supply conditions.

Looking ahead, no clear consensus for the direction of interest
rates currently exists. Perhaps, the primary focus going forward
will be the extent to which the increase in interest rates seen thus
far in 1996 will negatively impact future economic growth. Should
growth slow in the interest rate-sensitive sectors of the economy,
like housing, auto, and consumer spending, as many economists assert
is likely, then bond yields are likely to decline. Under such a
scenario, the municipal bond market's performance is likely to
closely mirror that of US Treasury bond market.

Fiscal Year in Review
Over the first half of the Fund's fiscal year, interest rates
steadily declined and Merrill Lynch Arizona Municipal Bond Fund's
net asset values appreciated rapidly. Early in 1996, the economic
picture changed from slow growth to an expanding economy. This
growing environment caused municipal bond yields to rise
dramatically over the second half of the Fund's fiscal year ended
July 31, 1996. Because of the conservative investment strategy we
employed this year, Merrill Lynch Arizona Municipal Bond Fund was
slightly hindered in its total returns to shareholders. However, the
Fund provided attractive yields for the 12 months ended July 31,
1996.
<PAGE>
Arizona municipal bonds continued to outperform compared to the rest
of the municipal bond market. This strong performance was caused by
continued demand and a lack of supply of new-issue Arizona municipal
bonds. This lack of supply was largely responsible for the Fund
remaining nearly fully invested even in these volatile times. We
continued to put a heavy emphasis on quality with 90% of the Fund's
portfolio holdings rated A or better by at least one of the major
rating agencies. We still believe that quality bonds will be the
most attractive investments over the long term. Looking ahead, we
will continue to monitor signs of economic growth and await further
supply of Arizona municipal bonds.

In Conclusion
We appreciate your ongoing interest in Merrill Lynch Arizona
Municipal Bond Fund, and we look forward to serving your investment
needs in the months and years to come.


Sincerely,

PERFORMANCE DATA


About Fund Performance

Investors are able to purchase shares of the Fund through the
Merrill Lynch Select Pricing SM System, which offers four pricing
alternatives:

* Class A Shares incur a maximum initial sales charge (front-end
  load) of 4% and bear no ongoing distribution or account maintenance
  fees. Class A Shares are available only to eligible investors.

* Class B Shares are subject to a maximum contingent deferred sales
  charge of 4% if redeemed during the first year, decreasing 1% each
  year thereafter to 0% after the fourth year. In addition, Class B
  Shares are subject to a distribution fee of 0.25% and an account
  maintenance fee of 0.25%. These shares automatically convert to
  Class D Shares after approximately 10 years. (There is no initial
  sales charge for automatic share conversions.)

* Class C Shares are subject to a distribution fee of 0.35% and an
  account maintenance fee of 0.25%. In addition, Class C Shares are
  subject to a 1% contingent deferred sales charge if redeemed within
  one year of purchase.

* Class D Shares incur a maximum initial sales charge of 4% and an
  account maintenance fee of 0.10% (but no distribution fee).

None of the past results shown should be considered a representation
of future performance. Investment return and principal value of
shares will fluctuate so that shares, when redeemed, may be worth
more or less than their original cost. Dividends paid to each class
of shares will vary because of the different levels of account
maintenance, distribution and transfer agency fees applicable to
each class, which are deducted from the income available to be paid
to shareholders.

1. Significant Accounting Policies:
Merrill Lynch Arizona Municipal Bond Fund (the "Fund") is part of
Merrill Lynch Multi-State Municipal Series Trust (the "Trust"). The
Fund is registered under the Investment Company Act of 1940 as a
diversified, open-end management investment company. The Fund offers
four classes of shares under the Merrill Lynch Select Pricing SM
System. Shares of Class A and Class D are sold with a front-end
sales charge. Shares of Class B and Class C may be subject to a
contingent deferred sales charge. All classes of shares have
identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class B, Class C and Class D
Shares bear certain expenses related to the account maintenance of
such shares, and Class B and Class C Shares also bear certain
expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its
account maintenance and distribution expenditures. The following is
a summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--Municipal bonds and other portfolio
securities in which the Fund invests are traded primarily in the
over-the-counter municipal bond and money markets and are valued at
the last available bid price in the over-the-counter market or on
the basis of yield equivalents as obtained from one or more dealers
that make markets in the securities. Financial futures contracts and
options thereon, which are traded on exchanges, are valued at their
settlement prices as of the close of such exchanges. Short-term
investments with remaining maturities of sixty days or less are
valued at amortized cost, which approximates market value.
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 Trustees of the Trust, including
valuations furnished by a pricing service retained by the Trust,
which may utilize a matrix system for valuations. The procedures of
the pricing service and its valuations are reviewed by the officers
of the Trust under the general supervision of the Trustees.

(b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its
portfolio against adverse movements in the debt 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
interest rate futures contracts and options on such futures
contracts for the purpose of hedging the market risk on existing
securities or the intended purchase of securities. 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.
<PAGE>
(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). Interest income is recognized on the accrual
basis. Discounts and market premiums are amortized into interest
income. Realized gains and losses on security transactions are
determined on the identified cost basis.

(e) Deferred organization expenses and prepaid registration fees--
Deferred organization expenses are charged to expense on a straight-
line basis over a five-year period. Prepaid registration fees are
charged to expense as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment
income are declared daily and paid monthly. Distributions of capital
gains are recorded on the ex-dividend dates. Distributions in excess
of realized capital gains are due primarily to differing tax
treatments for futures transactions and post-October losses.

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. The Fund has also entered into a Distribution
Agreement and Distribution Plans with Merrill Lynch Funds
Distributor, Inc. ("MLFD" or "Distributor"), a wholly-owned subsidi-
ary of Merrill Lynch Group, Inc.

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 based upon the average daily
value of the Fund's net assets at the following annual rates: 0.55%
of the Fund's average daily net assets not exceeding $500 million;
0.525% of average daily net assets in excess of $500 million but not
exceeding $1 billion; and 0.50% of average daily net assets in
excess of $1 billion. The Investment Advisory Agreement obligates
FAM to reimburse the Fund to the extent the Fund's expenses
(excluding interest, taxes, distribution fees, brokerage fees and
commissions, and extraordinary items) exceed 2.5% of the Fund's
first $30 million of average daily net assets, 2.0% of the next $70
million of average daily net assets, and 1.5% of the average daily
net assets in excess thereof. FAM's obligation to reimburse the Fund
is limited to the amount of the management fee. No fee payment will
be made to FAM during any fiscal year which will cause such expenses
to exceed expense limitation at the time of payment.
<PAGE>
Pursuant to the distribution plans (the "Distribution Plans")
adopted by the Fund in accordance with Rule 12b-1 under the
Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are
accrued daily and paid monthly at annual rates based upon the
average daily net assets of the shares as follows:

                                           Account     Distribution
                                       Maintenance Fee     Fee

Class B                                     0.25%          0.25%
Class C                                     0.25%          0.35%
Class D                                     0.10%           --

Pursuant to a sub-agreement with the Distributor, Merrill Lynch,
Pierce, Fenner & Smith Inc. ("MLPF&S"), a subsidiary of ML & Co.,
also provides account maintenance and distribution services to the
Fund. The ongoing account maintenance fee compensates the
Distributor and MLPF&S for providing account maintenance services to
Class B, Class C and Class D shareholders. The ongoing distribution
fee compensates the Distributor and MLPF&S for providing shareholder
and distribution-related services to Class B and Class C
shareholders.

and direct commissions and MLPF&S earned dealer concessions on sales
