TO OUR SHAREHOLDERS

Although the partial shutdown of the US Government curtailed the
release of most economic data in the latter part of the six-month
period ended January 31, 1996, it was nonetheless apparent that
gross domestic product (GDP) growth was losing momentum. Consumer
spending is barely growing, the industrial sector is at a virtual
standstill and, despite lower mortgage rates, there is little or no
pick-up in housing activity. With inflationary pressures subdued,
the Federal Reserve Board responded to the slowing economy by
continuing to modestly lower short-term interest rates.
Historically, it has taken some time for shifts in monetary policy
to have an impact on economic growth. Therefore, the Federal Reserve
Board's gradual shift to lowering interest rates, which began early
last year, may not be reflected in a pick-up in real economic growth
until later this year.
<PAGE>
The impasse between the Clinton Administration and Congress over the
Federal budget continues, although both sides have made concessions
since the debate began. It appears that investors are currently
focusing on the progress that has been made rather than on the
differences that remain. Initially, President Clinton proposed
deficits of about $190 billion annually through fiscal year 2002,
but now proposes balanced budgets, as do the Republicans. Current
indications are that a piecemeal budget accord is the most likely
outcome. Even without the proposed policy changes, it appears that
the US Federal budget deficit would remain stable at about 2% of GDP
for the rest of the decade. This would be far better than is the
case for most Group of Seven industrial nations, and for the United
States would represent a great improvement over the last 15 years.
Although this may fall short of investors' best expectations, it
appears that the Federal budget debate over the past year has
resulted in a trend toward a more conservative fiscal policy.

The Municipal Market
The municipal bond market rallied strongly during the six months
ended January 31, 1996. Long-term, tax-exempt revenue bond yields,
as measured by the Bond Buyer Revenue Bond Index, declined over 65
basis points (0.65%) to end the January period at 5.69%. Continued
weak economic conditions coupled with low inflation fostered a very
positive environment for almost all fixed-income investments during
the last three months of 1995. Long-term US Treasury bond yields
also declined approximately 65 basis points to 6.00% by January 31,
1996. Both US Treasury and long-term tax-exempt bond yields are near
their lowest levels in the past two years.

The municipal bond market had to contend with a number of
difficulties for much of 1995. Various tax reform proposals have
made the future tax advantage of municipal bonds uncertain. This
has, at a minimum, reduced the overall demand for tax-exempt
securities. At the same time, as municipal bond yields declined, tax-
exempt authorities have rushed to issue debt at near historic low
yield levels. During the six-month period ended January 31, 1996,
approximately $90 billion in municipal securities were underwritten,
an increase of over 30% compared to the same period last year.
However, as early 1995 issuance was significantly reduced, the last
12 months issuance of approximately $160 billion remained the same
as that issued a year earlier. Tax-exempt bond yields declined
throughout the six months ended January 31, 1996, despite investor
uncertainty and increased supply pressures.
<PAGE>
It is likely that the municipal market will regain much of the
technical support it enjoyed earlier in 1995. 1995 issuance remained
significantly below levels underwritten in 1993, when over $290
billion in long-term tax-exempt securities were issued. Also,
municipal investors received over $25 billion in bond maturities,
coupon income and early redemptions on January 1, 1996. This $25
billion is almost twice the average monthly issuance for 1995. The
amount of outstanding municipal securities will continue to decline
throughout 1996 and into early 1997. As the uncertainties
surrounding proposed tax reforms are resolved in 1996, the tax-
exempt bond market's renewed technical position should provide
support to municipal bond prices.

Many of the features that made tax-exempt products attractive to
investors last year are still in place. Long-term, A-rated municipal
revenue bonds continue to yield well over 90% of comparable US
Treasury bond yields. Historically, analysts have considered yields
in excess of 82% attractive for long-term investors. For example,
currently available tax-exempt bond yields generate taxable
equivalent yields in excess of 8.50% for an investor in the 36%
Federal income tax bracket. While the uncertainties regarding
potential changes in current tax law remain, it appears that, at
current price levels, bond investors have discounted at least some
of the uncertainty.

Looking ahead, it may be unreasonable to expect to duplicate the
double-digit returns produced by most tax-exempt issues in 1995,
given current municipal bond yields. Municipal bond yields would
have to decline to levels not seen since the 1960s in order to
generate such significant returns in the coming years. While the
current economic environment may still justify additional declines
in interest rates, it may be prudent to expect some period of
consolidation before the interest rate decline resumes. Tax-exempt
bond market performance in 1996 is likely to be generated more by
enhancing current income and limiting credit risk than by
significant interest rate declines.

Portfolio Strategy
We started the six-month period ended January 31, 1996 neutral on
the interest rate outlook. The economy seemed to be turning around;
the housing market started showing strength; retail sales were
exhibiting strong momentum; and the Federal Reserve Board began
easing monetary policy to spur what was believed to be a weak
economy. We focused on seeking to enhance tax-exempt income while
minimizing interest rate risk exposure. This strategy protected the
Fund from increased volatility while maintaining a competitive
yield.

By the end of September, we became more constructive on the interest
rate outlook in response to signs that the resurgent economy was
weakening and the risk of rising inflation subsiding. The strength
in housing and retail sales proved to be temporary and began
slipping going into the fourth quarter of 1995. Perception at this
time was that the easing of short-term interest rates initiated by
the Federal Reserve Board was not aggressive enough to stimulate the
economy. We started extending the Fund's duration by purchasing
bonds with greater price sensitivity to declining interest rates to
seek to enhance total return to our shareholders.
<PAGE>
This strategy proved very successful as we realized an attractive
total return while providing a competitive yield to our
shareholders. Looking ahead, we continue to be constructive on the
interest rate outlook. We maintained the Fund's cash reserves under
5% of net assets enabling the Fund to fully participate in the
expected continuing trend of lower tax-exempt interest rates.

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

Sincerely,

  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.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:
Merrill Lynch Oregon 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. These unaudited
financial statements reflect all adjustments which are, in the
opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a
normal recurring nature. 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.

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 FAM during any fiscal year which will cause such expenses
to exceed expense limitations at the time of payment. For the six
months ended January 31, 1996, FAM earned fees of $87,259, all of
which was voluntarily waived. FAM also reimbursed the Fund
additional expenses of $24,324.

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
                                        Maintenance   Distribution
                                            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.

For the six months ended January 31, 1996, 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

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.
