Past performance is not indicative of future results.
Principal value and investment return will fluctuate
so that an investor's shares, when redeemed, may be
worth more or less than their original cost. 1Source:
Prudential Investments LLC and Lipper Inc. The
cumulative total returns do not take into account
applicable sales charges. The average annual total
returns do take into account applicable sales
charges. Without the distribution and service (12b-1)
fee waiver of 0.05% for Class A shares, the returns
would have been lower. The Fund charges a maximum
front-end sales charge of 5% for Class A shares in
most circumstances, and a 12b-1 fee of up to 0.30%
annually. In some circumstances, Class A shares may
not be subject to a front-end sales charge, but may
be subject to a 1% contingent deferred sales charge
(CDSC) for the first year. Class B shares are subject
to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% for
the first six years respectively after purchase, and
a 12b-1 fee of 1.00% annually. Approximately seven
years after purchase, Class B shares will
automatically convert to Class A shares on a
quarterly basis. Class C shares are subject to a
front-end sales charge of 1%, a CDSC of 1% for shares
redeemed within 18 months of purchase, and a 12b-1
fee of 1.00% annually. Class Z shares are not subject
to a sales charge or 12b-1 fee. The returns in the
tables above do not reflect the deduction of taxes
that a shareholder would pay on fund distributions or
following the redemption of fund shares. 2Inception
date: 12/31/96. 3The Standard & Poor's MidCap 400
Stock Index (S&P MidCap 400 Index) is an unmanaged
index of 400 domestic stocks chosen for market size,
liquidity, and industry group representation. It

a broad look at how mid-cap stock prices have
performed in the United States. 4The Russell Midcap
Growth Index is an unmanaged index that measures the
performance of those Russell MidCap companies with
higher price-to-book ratios and higher forecasted
growth values. Investors cannot invest directly in an
index. 5The Lipper Mid-Cap Growth Funds Average
(Lipper Average) represents returns based on an
average return of all funds in the Lipper Mid-Cap
Growth Funds category for the periods noted. Funds
in the Lipper Average invest at least 75% of
their equity assets in companies with market
capitalizations (on a three-year weighted basis) less
than 300% of the dollar-weighted median market
capitalization of the middle 1,000 securities of the
S&P SuperComposite 1500 Index. Mid-cap growth funds
typically have an above-average price/earnings ratio,
price-to-book ratio, and three-year sales-per-share
growth value compared to the S&P MidCap 400 Index.
The returns for the S&P MidCap 400 Index, Russell
Midcap Growth Index, and the Lipper Average would be
lower if they included the effects of sales charges,
operating expenses of a mutual fund, or taxes.
Returns for the Lipper Average reflect the deduction
of operating expenses of a mutual fund, but not sales
charges or taxes.

DEAR SHAREHOLDER,
After fighting in Iraq ended in April 2003, U.S.
consumer confidence rose significantly and a more
optimistic tone pervaded the financial markets.
Major stock market indexes have continued to
improve, even as the long-standing bond
market rally persisted. While we welcome these
developments, it is important to remember that a wise
investor plans for tomorrow's needs today regardless
of the direction of financial markets.

Whether you are investing for your retirement, your
children's education, or for a new home for your
family, Prudential mutual funds offer advantages that
may help you reach your financial goals. Experienced
asset managers, working closely with research
analysts, employ time-tested investment processes
that were honed under a variety of market conditions.
We recommend that you consult a financial
professional who can help you strike the right
balance between your desire to obtain a particular
return from an investment and your tolerance for risk.

I was named president of the Prudential U.S. Emerging
Growth Fund, Inc. in March 2003. On behalf of the
Prudential Financial family, I would like to thank
you for your continued confidence in Prudential
mutual funds. We look forward to serving your future
investment needs.

Sincerely,


Judy A. Rice, President
Prudential U.S. Emerging Growth Fund, Inc.

             Notes to Financial Statements (Unaudited)

      Prudential U.S. Emerging Growth Fund, Inc. (the 'Fund'), is registered
under the Investment Company Act of 1940 as a diversified, open-end, management
investment company. The Fund was incorporated in Maryland on August 23, 1996.
The Fund issued 2,500 shares each of Class A, Class B, Class C and Class Z
common stock for $100,000 on October 21, 1996 to Prudential Investments, LLC,
('PI' or 'Manager'). Investment operations commenced on December 31, 1996.

      The Fund's investment objective is to achieve long-term capital
appreciation. It invests primarily in equity securities of small and
medium-sized U.S. companies, which will generally have a market capitalization
less than the largest capitalization of the Standard & Poor's Mid-Cap 400 Stock
Index, with the potential for above-average growth.

Note 1. Accounting Policies
The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements.

      Securities Valuation:    Securities traded on an exchange and NASDAQ
National Market securities are valued at the last closing price on such exchange
on the day of valuation or, if there was no sale on such day, at the mean
between the last reported bid and asked prices or at the last bid price on such
day in the absence of an asked price. Securities traded in the over-the-counter
market, including securities listed on exchanges whose primary market is
believed to be over-the-counter, are valued at market value using prices
provided by an independent pricing agent or principal market maker. Securities
for which reliable market quotations are not readily available or for which the
pricing agent or market maker does not provide a valuation or methodology, or
provides a valuation or methodology that, in the judgment of the subadviser,
does not represent fair value, are valued at fair value by a Valuation Committee
appointed by the Board of Trustees, in consultation with the Manager or
subadviser.

      Investments in mutual funds are valued at the net asset value as of the
close of the New York Stock Exchange on the date of valuation.

      Short-term securities which mature in more than 60 days are valued at
current market quotations. Short-term securities which mature in 60 days or less
are valued at amortized cost, which approximates market value.

      Repurchase Agreements:    In connection with transactions in repurchase
agreements with United States financial institutions, it is the Fund's policy
that its custodian or designated subcustodians under triparty repurchase
agreements, as the case may be, take possession of the underlying collateral
securities, the value of which

    12

             Notes to Financial Statements (Unaudited) Cont'd.

exceeds the principal amount of the repurchase transaction, including accrued
interest. To the extent that any repurchase transaction exceeds one business
day, the value of the collateral is marked-to-market on a daily basis to ensure
the adequacy of the collateral. If the seller defaults, and the value of the
collateral declines, or if bankruptcy proceedings are commenced with respect to
the seller of the security, realization of the collateral by the Fund may be
delayed or limited.

      Foreign Currency Translation:    The books and records of the Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:

      (i) market value of investment securities, other assets and
liabilities--at the closing daily rate of exchange.

      (ii) purchases and sales of investment securities, income and expenses--at
the rates of exchange prevailing on the respective dates of such transactions.

      Although the net assets of the Fund are presented at the foreign exchange
rates and market values at the close of the period, the Fund does not isolate
that portion of the results of operations arising as a result of changes in the
foreign exchange rates from the fluctuations arising from changes in the market
prices of long-term securities held at the end of the period. Similarly, the
Fund does not isolate the effect of changes in foreign exchange rates from the
fluctuations arising from changes in the market prices of portfolio securities
sold during the period. Accordingly, these realized foreign currency gains
(losses) are included in the reported net realized gains (losses) on investment
transactions.

      Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains or losses from the holding of foreign currencies,
currency gains (losses) realized between the trade and settlement dates on
security transactions, and the difference between the amounts of dividends,
interest and foreign taxes recorded on the Fund's books and the U.S. dollar
equivalent amounts actually received or paid. Net unrealized currency gains or
losses from valuing foreign currency denominated assets and liabilities (other
than investments) at period end exchange rates are reflected as a component of
net unrealized appreciation (depreciation) on investments and foreign
currencies.

      Foreign security and currency transactions may involve certain
considerations and risks not typically associated with those of domestic origin
as a result of, among other factors, the possibility of political and economic
instability or the level of governmental supervision and regulation of foreign
securities markets.

      Securities Lending:    The Fund may lend its securities to broker-dealers,
qualified banks and certain institutional investors. The loans are secured by
collateral in an
                                                                          13

amount equal to at least the market value at all times of the securities loaned
plus any accrued interest and dividends. The Fund may bear the risk of delay in
recovery of, or even loss of rights in, the securities loaned should the
borrower of the securities fail financially. The Fund receives compensation, net
of any rebate, for lending its securities in the form of interest on the
securities loaned, and any gain or loss in the market price of the securities
loaned that may occur during the term of the loan.

      Securities Transactions and Net Investment Income:    Securities
transactions are recorded on the trade date. Realized and unrealized gains and
losses on sales of portfolio securities are calculated on the identified cost
basis. Dividend income is recorded on the ex-dividend date; interest income is
recorded on the accrual basis. Expenses are recorded on the accrual basis which
may require the use of certain estimates by management.

      Net investment income or loss (other than distribution fees) and
unrealized and realized gains or losses are allocated daily to each class of
shares based upon the relative proportion of net assets of each class at the
beginning of the day.

      Dividends and Distributions:    Distributions from net investment income
and net capital gains, if any, are made annually. Distributions are recorded on
the ex-dividend date. Income distributions and capital gain distributions are
determined in accordance with income tax regulations which may differ from
generally accepted accounting principles.

      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 taxable net investment income and capital gains, if any, to its
shareholders. Therefore, no federal income tax provision is required.

      Withholding taxes on foreign dividends have been provided for in
accordance with the Fund's understanding of the applicable country's tax rules
and rates.

Note 2. Agreements
The Fund has a management agreement with PI. Pursuant to a subadvisory agreement
between PI and Jennison Associates LLC ('Jennison' or 'Subadviser'), Jennison
furnishes investment advisory services in connection with the management of the
Fund. Under the subadvisory agreement, Jennison, subject to the supervision of
PI, is responsible for managing the assets of the Fund in accordance with its
investment objective and policies. PI pays for the services of Jennison, the
cost of compensation of officers of the Fund, occupancy and certain clerical and
bookkeeping costs of the Fund. The Fund bears all other costs and expenses.

      The management fee paid to PI is computed daily and payable monthly, at an
annual rate of .60 of 1% of the Fund's average daily net assets up to $1 billion
and .55 of 1% of the average daily net assets in excess of $1 billion.

      The Fund has a distribution agreement with Prudential Investment
Management Services LLC ('PIMS'), which acts as the distributor of the Class A,
Class B, Class C and Class Z shares of the Fund. The Fund compensates PIMS for
distributing and servicing the Fund's Class A, Class B and Class C shares
pursuant to plans of distribution (the 'Class A, B and C Plans'), regardless of
expenses actually incurred by them. The distribution fees are accrued daily and
payable monthly. No distribution or service fees are paid to PIMS as distributor
for the Class Z shares of the Fund.

      Pursuant to the Class A, B and C Plans, the Fund compensates PIMS for
distribution-related activities at an annual rate of up to .30 of 1%, 1% and 1%
of the average daily net assets of the Class A, B and C shares, respectively.
Such expenses under the Plans were charged at an annual rate of .25 of 1%, 1%
and 1% of the average daily net assets of the Class A, B and C shares,
respectively, for the six months ended April 30, 2003.

      PIMS has advised the Fund that it received approximately $38,800 and
$6,000 in front-end sales charges resulting from sales of Class A shares and
Class C shares, respectively, during the six months ended April 30, 2003. From
these fees, PIMS paid such sales charges to affiliated broker-dealers, which in
turn paid commissions to salespersons and incurred other distribution costs.

      PIMS has advised the Fund that for the six months ended April 30, 2003, it
received approximately $151,000 and $2,600 in contingent deferred sales charges
imposed upon certain redemptions by Class B and Class C shareholders,
respectively.

      PI, PIMS and Jennison are indirect, wholly-owned subsidiaries of
Prudential Financial, Inc. ('Prudential').

      The Fund, along with other affiliated registered investment companies (the
'Funds'), is a party to a syndicated credit agreement ('SCA') with a group of
banks. For the six months ended April 30, 2003, the SCA provides for a
commitment of $500 million and allows the Funds to increase the commitment to $1
billion, if necessary. Interest on any borrowings will be at market rates. The
Funds pay a commitment fee of .08 of 1% of the unused portion of the SCA. The
commitment fee is accrued and paid quarterly on a pro rata basis by the Funds.
The purpose of the SCA is to serve as an alternative source of funding for
capital share redemptions. The expiration date of the SCA is May 2, 2003. The
Fund did not borrow any amounts pursuant to the SCA during the six months ended
April 30, 2003. On May 2, 2003, the SCA was renewed
                                                                          15

under the same terms and conditions ('May 2003 renewal'). The expiration date of
the May 2003 renewal is April 30, 2004.

Note 3. Other Transactions with Affiliates
Prudential Mutual Fund Services LLC ('PMFS'), an affiliate of PI and an
indirect, wholly-owned subsidiary of Prudential, serves as the Fund's transfer
agent. During the six months ended April 30, 2003, the Fund incurred fees of
approximately $607,400 for the services of PMFS. As of April 30, 2003,
approximately $98,800 of such fees were due to PMFS.

      The Fund pays networking fees to affiliated and unaffiliated
broker/dealers. These networking fees are payments made to broker/dealers that
clear mutual fund transactions through a national clearing system. The Fund
incurred approximately $86,200 in total networking fees, of which the amount
paid to Prudential Securities, Inc. ('PSI'), an affiliate of PI and an indirect,
wholly-owned subsidiary of Prudential was approximately $70,800 for the six
months ended April 30, 2003. As of April 30, 2003, approximately $11,200 of such
fees were due to PSI. These amounts are included in transfer agent's fees and
expenses in the Statement of Operations.

      PSI is the securities lending agent for the Fund. For the six months ended
April 30, 2003, PSI has been compensated in the amount of $31,793 for these
services of which approximately $7,300 is payable at period end.

      The Fund invests in the Taxable Money Market Series, a portfolio of
Prudential Core Investment Fund, pursuant to an exemptive order received from
the Securities and Exchange Commission. The Taxable Money Market Series is a
money market fund registered under the Investment Company Act of 1940, as
amended, and managed by PI. For the six months ended April 30, 2003, the Fund
earned income from the Taxable Money Market Series of approximately $85,350 and
$491,550, respectively, by investing its excess cash and collateral received
from securities lending.

Note 4. Portfolio Securities

for the six months ended April 30, 2003 were $463,892,130 and $463,045,337.

      As of April 30, 2003, the Fund had securities on loan with an aggregate
market value of $57,642,602. The Fund received $60,092,215 in cash as collateral
for securities on loan which was used to purchase highly liquid short-term
investments in accordance with the Fund's securities lending procedures.

Note 5. Tax Information

and $203,050,000 expires in 2010. Accordingly, no capital gains distributions
are expected to be paid to shareholders until net gains have been realized in
excess of such carryforward.

      The United States federal income tax basis of the Fund's investments and
the net unrealized appreciation as of April 30, 2003 were as follows:

      The difference between book basis and tax basis was primarily attributable
to deferred losses on wash sales.

Note 6. Capital
The Fund offers Class A, Class B, Class C and Class Z shares. Class A shares are
sold with a front-end sales charge of up to 5%. Certain investors who purchase
$1 million or more of Class A shares are subject to a 1% contingent deferred
sales charge during the first 12 months. Class B shares are sold with a
contingent deferred sales charge which declines from 5% to zero depending on the
period of time the shares are held. Class C shares are sold with a front-end
sales charge of 1% and a contingent deferred sales charge of 1% during the first
18 months. Class B shares will automatically convert to Class A shares on a
quarterly basis approximately seven years after purchase. A special exchange
privilege is also available for shareholders who qualify to purchase Class A
shares at net asset value. Class Z shares are not subject to any sales or
redemption charge and are offered exclusively for sale to a limited group of
investors.

      There are 2 billion shares of $.001 par value common stock authorized
divided into four classes, designated Class A, Class B, Class C and Class Z,
which consists of 1 billion, 500 million, 300 million and 200 million authorized
