TO OUR SHAREHOLDERS


In the July quarter, economic data generally showed evidence of
slowing activity. Gross domestic product growth for the first three
months of 1995 was reported at 2.7%, the weakest showing in the past
18 months. Other signs of a sluggish economy included lackluster
durable goods orders, slowing growth in the manufacturing sector,
and three consecutive months of declines in the Index of Leading
Economic Indicators, an occurrence which has often (but not always)
forecast recessions. As a result, concerns arose that the economic
"soft landing" could turn into an actual recession. However, at the
same time there were also expectations that a few months of very
slow or zero growth would be followed by a pickup in economic
activity later in the year. This view was supported by the
stronger-than-expected employ-ment data for June and an upward
revision in May's employment figures, as well as improving housing
activity measures and consumer confidence surveys.
<PAGE>
Thus far in 1995, economic developments have been very positive for
the US stock and bond markets, and most US stock market averages
recently have attained record levels. In contrast, the US dollar has
been persistently weak, especially relative to the yen. Following
the Federal Reserve Board's cut in short-term interest rates in
early July, continued signs of a moderating expansion and
well-contained inflationary pressures could provide further
assurance that the peak in US interest rates is behind us, creating
a stronger foundation for higher stock and bond prices. On the other
hand, indications of reaccelerating growth and increasing
inflationary pressures would likely suggest that higher interest
rates are on the horizon, a negative development for the US
financial markets. The outcome of the current deliberations on
reducing the Federal budget deficit will also play a role in the
investment outlook for the US capital markets.

The Municipal Market
Tax-exempt bond yields exhibited considerable volatility during the
three months ended July 31, 1995. Municipal bond yields initially
fell throughout May into early June as evidence of a slowing
domestic economy and moderate inflationary pressures accumulated. As
measured by the Bond Buyer Revenue Bond Index, yields of A-rated,
uninsured tax-exempt revenue bonds declined 35 basis points (0.35%)
to 5.94%. By late June, however, amid signs of a potentially
resurgent economy, particularly in the rebounding housing sector,
bond yields returned to their April quarter's levels of
approximately 6.30%. The lowering of short-term interest rates by
the Federal Reserve Board in early July temporarily restored
investor confidence and tax-exempt bond yields fell to 6.05%. As
additional economic indicators were released during July, investors
again saw signs that the economy was regaining momentum and that the
Federal Reserve Board action had been premature. Fears that an
expanding economy would have negative inflationary consequences
pushed municipal bond yields higher, ending the July 31, 1995
quarter essentially unchanged at 6.27%. US Treasury bond yields
exhibited a similar pattern of volatility during the July quarter.
However, US Treasury bond yields continued to decline, falling
approximately 50 basis points to 6.85%.

Municipal bonds have underperformed US Treasury securities for a
number of reasons. The record highs of the US equity market have
continued to attract retail investors seeking further capital
gains. Investor demand has also been diminished in recent months by
the "sticker shock" effect that periodically affects the municipal
bond market. Investors who had become accustomed to purchasing
tax-exempt securities in the 6.50%--7.00% range six to seven months
ago have demonstrated understandable reluctance to purchase similar
securities at current levels. The strong fundamental structure of
the municipal bond market, however, suggests that such hesitancy may
prove costly.
<PAGE>
However, the major reason by far for the tax-exempt market's recent
underperformance has been concerns regarding the implication for
municipal bonds' tax advantage resulting from various proposed tax
law changes (for example, flat tax, value-added tax or national
sales tax) that have reduced investor demand for tax-exempt
products. Such concerns are likely to quickly recede as investors
realize that such, if any, changes are unlikely to be enacted before
late 1996 at the earliest. Long-term investors will also recall 1986
when similar tax proposals were made, municipal bond yields
initially rose, in some instances, to over 100% of taxable yields.
Tax-exempt bond yields quickly declined as investors' fears proved
to be unfounded.

The municipal bond market's strong technical position has diminished
somewhat in recent months. New-issue supply over the last six months
has totaled approximately $71 billion, or a decline of over 20%
compared to the corresponding period in 1994. In recent months,
however, municipalities issued approximately $41 billion in new
securities, which represents only a 6% decline versus the same
period a year earlier. Investor demand has remained muted in recent
months despite significant funds available to investors. By the end
of July investors, both individual and institutional, are expected
to have received as much as $80 billion from tax-exempt bond
maturities, coupon payments and the proceeds of early bond
redemptions. Little new money has entered the municipal market in
recent months largely in response to the factors mentioned above.
Consequently, much of the technical support the municipal market
enjoyed earlier this year has evaporated, causing municipal bond
yields to decline at a slower rate than their taxable counterparts.

However, the recent relative underperformance of municipal bonds has
made them particularly attractive to long-term investors. Tax-exempt
bonds currently yield well over 90% of US Treasury securities. In
some instances, A-rated, long term revenue bonds have yielded almost
95% of US Treasury bonds. Analysts usually consider municipal bonds
yielding over 82% of US Treasury securities to be historically
attractive. With inflation-adjusted, "real" after-tax equivalent tax-
exempt yields of over 6.50%, municipal securities appear to
represent considerable value.

Current tax-exempt yield levels appear to be overcompensating for
any proposed changes in tax law can reasonably be expected to be
enacted. As Congressional hearings on this matter would continue
into 1996, and the revenue losses resultant from such changes become
more apparent, the likelihood of any significant changes to tax
codes and the resultant decline of municipal bonds' inherent tax
advantage should decline. Under such a scenario, tax-exempt bond
yields would quickly decline and currently available municipal bond
yields would return to their normal historic relationship.
<PAGE>
Fiscal Year in Review
At the beginning of the Fund's fiscal year, conditions in the bond
market caused us to become defensive and look to reduce the
volatility of the Fund's net asset value. As the backup in interest
rates became extreme, we anticipated an improving situation for
bonds and extended maturities through spring of 1995. As the bond
market improved, we continued to believe that the Federal Reserve
Board would need to relax monetary conditions to encourage growth,
and the Fund participated in the resulting municipal bond market
rally. After the Federal Reserve Board signaled a change in monetary
policy by lowering interest rates, investors initially showed their
approval. However, investor sentiment turned sharply negative and
the market abruptly reversed course, causing a backup in interest
rates. Nevertheless, our strategy of being fully invested in a
generally declining interest rate environment produced a positive
total return for our shareholders.

Municipal bond market yields, as measured by the Bond Buyer Revenue
Bond Index, began and ended the year almost unchanged at 6.47% and
6.27%, respectively. This belies the tremendous fluctuations in
yields during the year from a high of 7.37% to a low of 5.94%.
During the year ended July 31, 1995, we attempted to take advantage
of opportunities to purchase and hold securities which would benefit
the Fund as long-term holdings. Many of the higher-yielding
healthcare holdings, for example, represent value which investors in
general have yet to recognize. We believe that this strategy will
benefit shareholders over time.

Looking ahead, we are cautious regarding the prospects for a
continuation of a bond market rally and may look for opportunities
to seek to protect the Fund's net asset value.

In Conclusion
We appreciate your ongoing interest in Merrill Lynch Ohio Municipal
Bond Fund, and we look forward to assisting you with your financial
needs in the months and years ahead.

Sincerely,

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.

* 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).

Performance data for all the Fund's shares are presented in the
"Total Return Based on a $10,000 Investment" graphs on page 5 and
the "Recent Performance Results" table below. Data for the Fund's
Class A and Class B Shares are presented in the "Performance
Summary" tables on page 6 and "Average Annual Total Return" tables
on page 5. Data for Class C and Class D Shares are also presented in
the "Aggregate Total Return" tables on page 5.

The "Recent Performance Results" table shows investment results
before the deduction of any sales charges for Class A and Class B
Shares for the 12-month and 3-month periods ended July 31, 1995 and
for Class C and Class D Shares for the since inception and 3-month
periods ended July 31, 1995. All data in this table assume
imposition of the actual total expenses incurred by each class of
shares during the relevant period.

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.

NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies:
Merrill Lynch Ohio 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
non-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.
<PAGE>
(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.

(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
subsidiary 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 the Investment Adviser during any fiscal year which will
cause such expenses to exceed expense limitations at the time of
payment. For the year ended July 31, 1995, FAM earned fees of
$402,455, of which $19,871 was voluntarily waived.

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%           --

<PAGE>
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.

For the year ended July 31, 1995, MLFD earned underwriting discounts
and MLPF&S earned dealer concessions on sales of the Fund's Class A
and Class D Shares as follows:


                                       MLFD         MLPF&S

Class A                                $310         $2,251
Class D                                $112         $  625


MLPF&S received contingent deferred sales charges of $150,198
relating to transactions in Class B Shares of beneficial interest
and $123 relating to transactions in Class C Shares of beneficial
interest for the Fund for the year ended July 31, 1995.

Merrill Lynch Financial Data Services, Inc. ("MLFDS"), a
wholly-owned subsidiary of ML & Co., is the Fund's transfer agent.

Accounting services are provided to the Fund by FAM at cost.

Certain officers and/or trustees of the Fund are officers and/or
directors of FAM, PSI, MLPF&S, MLFDS, MLFD, and/or ML & Co.

The Board of Trustees and Shareholders,

We have audited the accompanying statement of assets and
liabilities, including the schedule of investments, of Merrill Lynch
Ohio Municipal Bond Fund of Merrill Lynch Multi-State Municipal
Series Trust as of July 31, 1995, the related statements of
operations for the year then ended and changes in net assets for
each of the years in the two-year period then ended, and the
financial highlights for each of the years in the three-year period
then ended and for the period February 28, 1992 (commencement of
operations) to July 31, 1992. These financial statements and the
financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our
audits.
<PAGE>
We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.
Our procedures included confirmation of securities owned at July 31,
1995 by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights
present fairly, in all material respects, the financial position of
Merrill Lynch Ohio Municipal Bond Fund of Merrill Lynch Multi-State
Municipal Series Trust as of July 31, 1995, the results of its
operations, the changes in its net assets, and the financial
highlights for the respective stated periods in conformity with
generally accepted accounting principles.
