DEAR SHAREHOLDER:
===============================================================================
        We are pleased to present the third annual report on the operations of
Dean Witter Multi-State Municipal Series Trust for the fiscal year ended
November 30, 1993.

MARKET CONDITIONS

        For much of the period under review, long-term interest rates were near
their lowest levels in almost 20 years. The passage and signing of the Clinton
administration's Revenue Reconciliation Act during the summer made higher
marginal income tax rates a reality and strengthened demand for tax-exempt
bonds. Over the past 12 months, municipal bond yields, as measured by  The Bond
Buyer Revenue Bond Index, fell 77 basis points from 6.48 percent to 5.71
percent.

        Municipal issuers continued to take advantage of lower interest rates
by refunding older, higher-coupon debt at an unprecedented pace. A new record
for underwriting volume has already been set this year. The total of $261
billion issued during the first 11 months of 1993 surpassed the previous high
of $235 billion for all of 1992. Refundings accounted for two-thirds of total
new-issue sales. Underwriting backed by insurance represented 37 percent of the
new-issue market. The 10 states that comprise the Multi-State Municipal Series
Trust issued nearly half of the total volume.

INVESTMENT STRATEGY

        New investments in each portfolio of the Fund have been focused on the
20-year maturity range, since the yield curve flattens beyond 20 years. This
has resulted in weighted average portfolio maturities which are up to four
years shorter than at the end of fiscal year 1992. As of November 30, 1993 the
average maturities of the various portfolios ranged between 19 and 23 years.
Call protection, however, has been maintained at an average of 8 years. The
Fund continued to meet its investment objective during the fiscal year by
providing shareholders with a high level of current income exempt from both
federal and specific state income taxes consistent with preservation of
capital. The strategy of the portfolios was to remain fully invested with a
preference for investment grade issues rated "A" or better. Income dividends
have been sustained by consistently investing cash inflows in long-term
maturities.

        The charts that follow illustrate the growth of a $10,000 investment in
each Series from inception (January 15, 1991 for all Series except Arizona,
which commenced operations on April 30, 1991) through the fiscal year ended
November 30, 1993 versus the performance of a similar investment in the Lehman
Brothers Municipal Bond Index.

        Please note that the Investment Manager of the Fund continued to waive
management fees and assume expenses to the extent that they exceeded 50 basis
points (0.50 percent) of daily net assets through calendar year-end 1993. This
expense limitation allowed each Series to maintain a competitive yield in the
marketplace. However, on January 1, 1994 the five larger Series--Arizona,
California, Florida, New Jersey and Pennsylvania--began paying all of their
expenses. The impact is expected to be a modest 15 to 20 basis point (0.15
percent to 0.20 percent) decline in yield. The five smaller  Series--
Massachusetts, Michigan, Minnesota, New York and Ohio--will continue to have
expenses in excess of 50 basis points of daily net assets absorbed by Dean
Witter InterCapital Inc. through June 30, 1994.

        For your convenience, we have summarized details about the various
Series portfolios on the following pages. Here you may review the credit
quality, maturity, call protection, distributions, performance and tax-free and
taxable equivalent yields of each portfolio.

        We appreciate your support of Dean Witter Multi-State Municipal Series
Trust and look forward to continuing to serve your investment needs.

                                Very truly yours,

                                Charles A. Fiumefreddo

securities and evaluations by its staff, in each case based on information
concerning market transactions and quotations from dealers which reflect the
bid side of the market each day. The Fund's portfolio securities are thus
valued by reference to a combination of transactions and quotations for the
same or other securities believed to be comparable in quality, coupon,
maturity, type of issue, call provisions, trading characteristics and other
features deemed to be relevant.

B. Accounting for Investments--Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). In computing net
investment income, the Fund amortizes premiums and original issue discounts.
Additionally, with respect to market discount on bonds purchased after April
30, 1993, a portion of any capital gain realized upon disposition is
recharacterized as taxable investment income. Realized gains and losses on
security transactions are determined on the identified cost method. Interest
income is accrued daily.

C. Federal Income Tax Status--It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable and non-taxable income to its
shareholders. Accordingly, no federal income tax provision is required.

</TABLE>

5. FEDERAL INCOME TAX STATUS--At November 30, 1993, the Florida Series had net
capital loss carryovers of approximately $131,200 of which $8,400 will be
available through November 30, 1999, $28,800 will be available through November
30, 2000 and $94,000 will be available through November 30, 2001 to offset
future capital gains to the extent provided by regulations. During the year
ended November 30, 1993, the California Series, the Massachusetts Series, the
Michigan Series, the New York Series and the Pennsylvania Series utilized all
of their carryover losses of $66,900, $2,900, $8,400, $47,100 and $17,500,
respectively. Capital losses incurred after October 31 within the taxable year
are deemed to arise on the first business day of the Fund's next taxable year.
The Florida Series incurred and elected to defer a net capital loss of
approximately $5,400 during fiscal 1993. To the extent that this net capital
loss carryover is used to offset future capital gains, it is probable that the
gains so offset will not be distributed to shareholders.

6. DIVIDENDS AND DISTRIBUTIONS--On a daily basis the Fund declares, on behalf
of each Series, dividends from its net investment income. Such dividends are
payable monthly. Net realized capital gains, if any, from all ten portfolios
are distributed at least annually.

DEAN WITTER MULTI-STATE MUNICIPAL SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
===============================================================================
To the Shareholders and Trustees of Dean Witter Multi-State Municipal Series
Trust

In our opinion, the accompanying statements of assets and liabilities,
including the portfolios of investments, and the related statements of
operations and of changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of the Arizona Series,
the California Series, the Florida Series, the Massachusetts Series, the
Michigan Series, the Minnesota Series, the New Jersey Series, the New York
Series, the Ohio Series and the Pennsylvania Series (constituting the Dean
Witter Multi-State Municipal Series Trust (the "Fund")) at November 30, 1993,
and the results of each of their operations for the year then ended, the
changes in each of their net assets for each of the two years in the period
then ended and the financial highlights for each of the two years in the period
then ended and for the period January 15, 1991 (commencement of operations for
all Series except the Arizona Series) and April 30, 1991 (commencement of
operations for the Arizona Series) through November 30, 1993, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities owned at November 30,
1993 by correspondence with the custodian and a broker, provide a reasonable
basis for the opinion expressed above.
