Semi-Annual Report

This report provides management's discussion of fund performance for
AllianceBernstein Mid-Cap Growth Fund (the "Fund") for the semi-annual
reporting period ended January 31, 2004.

Investment Objective and Policies

AllianceBernstein Mid-Cap Growth Fund is an open-end, diversified investment
company that seeks long-term growth of capital and income primarily through
investments in common stocks that Alliance Capital believes will appreciate in
value. The Fund invests predominantly in the stocks of mid-capitalization
companies.

Investment Results

The following table provides the Fund's investment results for the six- and
12-month periods ended January 31, 2004. For comparison, we have also provided
performance for the Fund's benchmark, the Russell MidCap Growth Index, which is
a measure of mid-cap stock performance.

*    The Fund's investment results are for the periods shown and are based on
the net asset value (NAV) of each class of shares as of January 31, 2004.
Returns do not reflect the deduction of taxes that a shareholder would pay on
fund distributions or the redemption of fund shares. All fees and expenses
related to the operation of the Fund have been deducted, but no adjustment has
been made for sales charges that may apply when shares are purchased or
redeemed. Returns for Advisor Class shares will vary due to different expenses
associated with this class. Returns for the Fund include the reinvestment of
any distributions paid during each period. Past performance is no guarantee of
future results.

     The unmanaged Russell MidCap Growth Index does not reflect fees and
expenses associated with the active management of a mutual fund portfolio. The
Index measures the performance of those Russell mid-cap companies with higher
price-to-book ratios and higher forecasted growth values. The stocks are also
members of the Russell 1000 Growth Index. Investors cannot invest directly in
an index, and its results are not indicative of any specific investment,
including AllianceBernstein Mid-Cap Growth Fund.

     Additional investment results appear on pages 4-6.

For the six- and 12-month periods ended January 31, 2004, the Fund
significantly outperformed its benchmark, the Russell MidCap Growth Index, due
to overweight positions and good stock selection in technology,
telecommunication services and con-

sumer discretionary stocks. Technology was the largest contributor to
performance with contributions primarily from semiconductor, software and
networking holdings. Underlying demand from the consumer and the enterprise
markets was stronger than expected, spurring better than expected earnings and
sales results during the second half of 2003. After three years of little to no
business investment, the surprises during the early stages of this expansion,
in some cases, have been dramatic. The Fund also benefited meaningfully from
several wireless and internet stocks. Health care as a whole contributed to
performance, with biotechnology stocks contributing the most to the sector.

The Fund's overweight position in the airline industry was the largest drag on
performance. Airlines were hit by higher than expected fuel costs, which they
were unable to pass along to consumers. The Fund's defense holdings performed
poorly on a relative basis as concerns surrounding government spending and the
mounting deficit weighed on the stocks.

Market Review and Investment Strategy

The equity markets rose sharply during the second half of the year as fears
regarding the geopolitical landscape began to subside and corporate governance
issues no longer dominated the headlines. Improving company fundamentals and a
rebounding economy increased investor appetite for stocks. Technology, internet
and telecommunication companies were the prime beneficiaries of the asset
allocation shift that took place. The Fund was well positioned in technology
with broad exposure to semiconductor, software, networking, security and
storage stocks. We focused on companies that were in a position to capitalize
on the broadband revolution now underway. We held a number of internet stocks
that broadly played into this theme.

In mid-2003, as energy and defense stocks corrected, we used the proceeds from
our profit-taking in technology stocks to increase the Fund's positions in both
sectors. The wireless service group was one of the more volatile groups during
the period, fueled by uncertainty surrounding the potential impact of wireless
local number portability. We used the volatility as an opportunity to build the
Fund's wireless positions. We decided to underweight financial service stocks,
choosing instead to increase the Fund's cyclical exposure through overweight
positions in technology, industrials and producer durables. The Fund's position
in high beta, early stage biotechnology companies was a good counterweight to
the underweight position in the health care sector.

The performance shown above represents past performance and does not guarantee
future results. Current performance may be lower or higher than the performance
information shown. The Fund's investment results are for the periods shown and
are based on the Fund's Class A shares at net asset value (NAV). All fees and
expenses related to the operation of the Fund have been deducted. NAV returns
do not reflect sales charges; if sales charges were reflected, the Fund's
quoted performance would be lower. Fund returns do not reflect the deduction of
taxes that a shareholder would pay on fund distributions or the redemption of
fund shares. Fund returns reflect the reinvestment of dividends and/or capital
gains distributions in additional shares.

SEC returns reflect the 4.25% maximum front-end sales charge for Class A shares.

The investment return and principal value of an investment in the Fund will
fluctuate as the prices of the individual securities in which it invests
fluctuate, so that shares, when redeemed, may be worth more or less than their
original cost. You should consider the investment objectives, risks, charges
and expenses of the Fund carefully before investing. For a free copy of the
Fund's prospectus, which contains this and other information, visit our web
site at www.alliancebernstein.com or call your financial advisor or Alliance at
(800) 227-4618. Please read the prospectus carefully before you invest. You may
obtain current month-end performance information from our web site at
www.alliancebernstein.com (click on Investors/Products & Services/Mutual Funds).

A Word About Risk: The Fund can invest in foreign securities. Foreign markets
can be more volatile than the U.S. market due to increased risks of adverse
issuer, political, regulatory, market or economic developments. In addition,
fluctuations in the value of investments in foreign currency denominated
securities may be magnified by changes in foreign exchange rates. While the
Fund invests principally in common stocks and other equity securities, in order
to achieve its investment objectives, the Fund may at times use certain types
of investment derivatives, such as options, futures, forwards and swaps. These
instruments involve risks different from, and in certain cases, greater than
the risks presented by more traditional investments. These risks are more fully
discussed in the prospectus. Many equity stocks, and smaller capitalization
stocks in particular, have experienced significant gains over the past year.
There is no assurance that the gains will continue.

NOTES TO FINANCIAL STATEMENTS
January 31, 2004 (unaudited)


NOTE A

Significant Accounting Policies

The AllianceBernstein Mid-Cap Growth Fund, Inc. (the "Fund") is registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The Fund offers Class A, Class B, Class C and Advisor Class
shares. Class A shares are sold with a front-end sales charge of up to 4.25%
for purchases not exceeding $1,000,000. With respect to purchases of $1,000,000
or more, Class A shares redeemed within one year of purchase may be subject to
a contingent deferred sales charge of 1%. Class B shares are currently sold
with a contingent deferred sales charge which declines from 4% to zero
depending on the period of time the shares are held. Class B shares will
automatically convert to Class A shares eight years after the end of the
calendar month of purchase. Class C shares are subject to a contingent deferred
sales charge of 1% on redemptions made within the first year after purchase.
Advisor Class shares are sold without an initial or contingent deferred sales
charge and are not subject to ongoing distribution expenses. Advisor Class
shares are offered to investors participating in fee-based programs and to
certain retirement plan accounts. All four classes of shares have identical
voting, dividend, liquidation and other rights, except that each class bears
different distribution expenses and has exclusive voting rights with respect to
its distribution plan. The financial statements have been prepared in
conformity with accounting principles generally accepted in the United States
which require management to make certain estimates and assumptions that affect
the reported amounts of assets and liabilities in the financial statements and
amounts of income and expenses during the reporting period. Actual results
could differ from those estimates. Additional information about some of the
items discussed in these Notes to Financial Statements is contained in the
Fund's Statement of Additional Information, which is available upon request.
The following is a summary of significant accounting policies followed by the
Fund.

1. Security Valuation

In accordance with Pricing Policies adopted by the Board of Directors of the
Fund (the "Pricing Policies") and applicable law, portfolio securities are
valued at current market value or at fair value. The Board of Directors has
delegated to Alliance Capital Management, L.P. (the "Manager"), subject to the
Board's continuing oversight, certain responsibilities with respect to the
implementation of the Pricing Policies. Pursuant to the Pricing Policies,
securities for which market quotations are readily available are valued at
their current market value. In general, the market value of these securities is
determined as follows:

Securities listed on a national securities exchange or on a foreign securities
exchange are valued at the last sale price at the close of the exchange or
foreign securities exchange. If there has been no sale on such day, the
securities are valued at the mean of the closing bid and asked prices on such
day. If no bid or asked prices are quoted on such day, then the security is
valued in good faith at


- -------------------------------------------------------------------------------
                                     ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 15



fair value in accordance with the Pricing Policies. Securities listed on more
than one exchange are valued by reference to the principal exchange on which
the securities are traded; securities not listed on an exchange but traded on
The Nasdaq Stock Market, Inc. ("NASDAQ") are valued in accordance with the
NASDAQ Official Closing Price; listed put or call options are valued at the
last sale price. If there has been no sale on that day, such securities will be
valued at the closing bid prices on that day; open futures contracts and
options thereon are valued using the closing settlement price or, in the
absence of such a price, the most recent quoted bid price. If there are no
quotations available for the day of valuations, the last available closing
settlement price is used; securities traded in the over-the-counter market,
(but excluding securities traded on NASDAQ) are valued at the mean of the
current bid and asked prices as reported by the National Quotation Bureau or
other comparable sources; U.S. Government securities and other debt instruments
having 60 days or less remaining until maturity are valued at amortized cost if
their original maturity was 60 days or less, or by amortizing their fair value
as of the 61st day prior to maturity if their original term to maturity
exceeded 60 days; fixed-income securities, including mortgage backed and asset
backed securities, may be valued on the basis of prices provided by a pricing
service or at a price obtained from one or more of the major broker/dealers. In
cases where broker/dealer quotes are obtained, the Pricing Policies provide
that the Adviser may establish procedures whereby changes in market yields or
spreads are used to adjust, on a daily basis, a recently obtained quoted price
on a security; and OTC and other derivatives are valued on the basis of a
quoted bid price or spread from a major broker/dealer in such security.
Securities for which market quotations are not readily available are valued at
fair value in accordance with the Pricing Policies.

2. Currency Translation

Assets and liabilities denominated in foreign currencies and commitments under
forward exchange currency contracts are translated into U.S. dollars at the
mean of the quoted bid and asked prices of such currencies against the U.S.
dollar. Purchases and sales of portfolio securities are translated into U.S.
dollars at the rates of exchange prevailing when such securities were acquired
or sold. Income and expenses are translated into U.S. dollars at rates of
exchange prevailing when accrued.

Net realized gain or loss on foreign currency transactions represents foreign
exchange gains, losses from sales and maturities of foreign fixed income
investments, foreign currency exchange contracts, holding of foreign
currencies, currency gains or losses realized between the trade and settlement
dates on  foreign investment transactions, and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent amounts actually received or paid.
Net unrealized currency gains and losses from valuing foreign currency
denominated assets and liabilities


- -------------------------------------------------------------------------------
16 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND



at period end exchange rates are reflected as a component of net unrealized
appreciation or depreciation of investments and foreign currency denominated
assets and liabilities.

3. Taxes

It is the Fund's policy to meet the requirements of the Internal Revenue Code
applicable to regulated investment companies and to distribute all of its
investment company taxable income and net realized gains, if any, to
shareholders. Therefore, no provisions for federal income or excise taxes are
required.

4. Investment Income and Investment Transactions

Dividend income is recorded on the ex-dividend date. Interest income is accrued
daily. Investment transactions are accounted for on the trade date securities
are purchased or sold. Investment gains and losses are determined on the
identified cost basis. The Fund accretes discounts as adjustments to interest
income.

5. Income and Expenses

All income earned and expenses incurred by the Fund are borne on a pro rata
basis by each outstanding class of shares, based on the proportionate interest
in the Fund represented by the net assets of such class, except that the Fund's
Class B and Class C shares bear higher distribution and transfer agent fees
than Class A and Advisor Class shares. Advisor Class shares have no
distribution fees.

6. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the
ex-dividend date. Income dividends and capital gains distributions are
determined in accordance with federal tax regulations and may differ from those
determined in accordance with accounting principles generally accepted in the

NOTE E

Securities Lending

The Fund has entered into a securities lending agreement with UBS Warburg LLC
(the "Lending Agent"). Under the terms of the agreement, the Lending Agent, on
behalf of the Fund, administers the lending of portfolio securities to certain
broker-dealers. In return, the Fund receives fee income from the lending
transactions or it retains a portion of interest on the investment of any cash
received as collateral. The Fund also continues to receive dividends or
interest on the securities loaned. Unrealized gain or loss on the value of the
securities loaned that may occur during the term of the loan will be reflected
in the accounts of the Fund. All loans are continuously secured by collateral
exceeding the value of the securities loaned. All collateral consists of either
cash or U.S. government securities. The Lending Agent may invest the cash
collateral received in an eligible money market vehicle in accordance with the
investment restrictions of the Fund. The Lending Agent will indemnify the Fund
for any loss resulting from a borrower's failure to return a loaned security
when due. As of January 31, 2004, the Fund had loaned securities with a value
of $95,560,961 and received cash collateral which was invested in a money
market fund valued at $98,550,100 as included in the accompanying portfolio of
investments. For the period ended January 31, 2004, the Fund earned fee income
of $42,712 which is included in the accompanying statement of operations.

Components of Accumulated Earnings (Deficit)

The tax character of distributions to be paid for the year ending July 31, 2004
will be determined at the end of the current fiscal year. As of July 31, 2003,
the components of accumulated earnings/(deficit) on a tax basis were as follows:

Accumulated capital and other losses                           $(256,609,415)(a)
Unrealized appreciation/(depreciation)                           110,228,489(b)

(a) On July 31, 2003, the Fund had a net capital loss carryforward of
$256,609,415 of which $148,929,597 expires in the year 2009 and $107,679,818
expires in the year 2010. To the extent future capital gains are offset by
capital loss carryforward, such gains will not be distributed. The Fund
utilized $2,695,059 of capital loss carryforward during the year.

(b) The difference between book-basis and tax-basis unrealized
appreciation/(depreciation) is attributable primarily to the tax deferral of
losses on wash sales.

Legal Proceedings

As has been previously reported in the press, the Staff of the U.S. Securities
and Exchange Commission ("SEC") and the New York Attorney General's Office
("NYAG") have been investigating practices in the mutual fund industry
identified as "market timing" and "late trading" of mutual fund shares. Certain
other regulatory authorities have also been conducting investigations into
these practices within the industry and have requested that Alliance Capital
Management L.P. ("Alliance Capital"), the Fund's Adviser, provide information
to them. Alliance Capital has been cooperating and will continue to cooperate
with all of these authorities.


- -------------------------------------------------------------------------------
                                     ALLIANCEBERNSTEIN MID-CAP GROWTH FUND o 21



On December 18, 2003, Alliance Capital confirmed that it had reached terms with
the SEC and the NYAG for the resolution of regulatory claims relating to the
practice of "market timing" mutual fund shares in some of the AllianceBernstein
Mutual Funds. The agreement with the SEC is reflected in an Order of the
Commission ("SEC Order"). The agreement with the NYAG is subject to final,
definitive documentation. Among the key provisions of these agreements are the
following:

  (i)   Alliance Capital agreed to establish a $250 million fund (the
"Reimbursement Fund") to compensate mutual fund shareholders for the adverse
effects of market timing attributable to market timing relationships described
in the SEC Order. According to the SEC Order, the Reimbursement Fund is to be
paid, in order of priority, to fund investors based on (i) their aliquot share
of losses suffered by the fund due to market timing, and (ii) a proportionate
share of advisory fees paid by such fund during the period of such market
timing;

  (ii)  Alliance Capital agreed to reduce the advisory fees it receives from
some of the AllianceBernstein long-term, open-end retail funds, commencing
January 1, 2004, for a period of at least five years. The determination of
which funds will have their fees reduced and to what degree is subject to the
terms of the definitive agreement with the NYAG; and

  (iii) Alliance Capital agreed to implement changes to its governance and
compliance procedures. Additionally, the SEC Order contemplates that Alliance
Capital's registered investment company clients, including the Fund, will
introduce governance and compliance changes.

The special committee of Alliance Capital's Board of Directors, comprised of
the members of Alliance Capital's Audit Committee and the other independent
member of the Board, is continuing to direct and oversee an internal
investigation and a comprehensive review of the facts and circumstances
relevant to the SEC's and the NYAG's investigations.

In addition, the Independent Directors of the Fund ("the Independent
Directors") have initiated an investigation of the above-mentioned matters with
the advice of an independent economic consultant and independent counsel. The
Independent Directors have formed a special committee to supervise the
investigation.

On October 2, 2003, a putative class action complaint entitled Hindo et al. v.
AllianceBernstein Growth & Income Fund et al. (the "Hindo Complaint") was filed
against Alliance Capital; Alliance Capital Management Holding L.P.; Alliance
Capital Management Corporation; AXA Financial, Inc.; certain of the
AllianceBernstein Mutual Funds, including the Fund; Gerald Malone; Charles


- -------------------------------------------------------------------------------
22 o ALLIANCEBERNSTEIN MID-CAP GROWTH FUND



Schaffran (collectively, the "Alliance Capital defendants"); and certain other
defendants not affiliated with Alliance Capital. The Hindo Complaint was filed
in the United States District Court for the Southern District of New York by
alleged shareholders of two of the AllianceBernstein Mutual Funds. The Hindo
Complaint alleges that certain of the Alliance Capital defendants failed to
disclose that they improperly allowed certain hedge funds and other
unidentified parties to engage in late trading and market timing of
AllianceBernstein Fund securities, violating Sections 11 and 15 of the
Securities Act, Sections 10(b) and 20(a) of the Exchange Act, and Sections 206
and 215 of the Advisers Act. Plaintiffs seek an unspecified amount of
compensatory damages and rescission of their contracts with Alliance Capital,
including recovery of all fees paid to Alliance Capital pursuant to such
contracts.

Since October 2, 2003, approximately 40 additional lawsuits making factual
allegations similar to those in the Hindo Complaint were filed against Alliance
Capital and certain other defendants, some of which name the Fund as a
defendant. All of these lawsuits seek an unspecified amount of damages.

As a result of the matters discussed above, investors in the AllianceBernstein
Mutual Funds may choose to redeem their investments. This may require the
AllianceBernstein Mutual Funds to sell investments held by those funds to
provide for sufficient liquidity and could also have an adverse effect on the
investment performance of the AllianceBernstein Mutual Funds.
