Prudential MoneyMart Assets, Inc.
              Supplement dated October 31, 1997 to
               Prospectus dated February 28, 1997

The following information supplements "Other Investments and Policies"
in the Prospectus:

          When-Issued and Delayed Delivery Securities. The Fund may purchase
      or sell securities on a when-issued or delayed delivery basis. 
      When-issued or delayed delivery transactions arise when securities are 
      purchased or sold by the Fund with payment and delivery taking place in 
      the future in order to secure what is considered to be an advantageous 
      price and yield to the Fund at the time of entering into the transaction.
      The purchase price and the interest rate payable on the securities are 
      fixed on the transaction date. The securities so purchased are subject 
      to market fluctuations and no interest accrues to the Fund until delivery
      and payment take place. The Fund's Custodian will maintain, in a 
      segregated account of the Fund, cash, U.S. Government securities or 
      other liquid unencumbered assets, marked-to-market daily, having a value
      equal to or greater than the Fund's purchase commitments. The purchase
      of securities on a "when-issued" basis may involve additional risks. See
      "Investment Objective and Policies - When-Issued and Delayed Delivery
      Securities" in the Statement of Additional Information.
