PROSPECTUS SUPPLEMENT TO PROSPECTUS DATED JANUARY 29, 1998
6,044,404 SHARES
NETSCAPE COMMUNICATIONS CORPORATION
COMMON STOCK
------------------------
This Prospectus Supplement (the "Prospectus Supplement") supplements the
Prospectus dated January 29, 1998 (the "Prospectus") of Netscape Communications
Corporation ("Netscape" or the "Company") relating to the public offering (which
is not being underwritten) and sale of up to 6,044,404 shares of Common Stock,
par value $0.0001 per share (the "Shares"), of the Company, which may be offered
and sold from time to time by certain stockholders of the Company or by
pledgees, donees, transferees or other successors in interest that receive such
shares as a gift, partnership distribution or other non-sale related transfer
(the "Selling Stockholders"). The Company will receive no part of the proceeds
of such sales. All of the Shares were originally issued by the Company in
connection with the Company's acquisition of KIVA Software Corporation, a
California corporation ("KIVA"), by and through a merger of a wholly-owned
subsidiary of Netscape, Knife Acquisition Corporation, with and into KIVA. This
Prospectus Supplement should be read in conjunction with the Prospectus and this
Prospectus Supplement is qualified by reference to the Prospectus, except to the
extent that the information herein contained supersedes the information
contained in the Prospectus. Capitalized terms used in this Prospectus
Supplement and not otherwise defined herein have the meanings specified in the
Prospectus.
------------------------
THE DATE OF THIS PROSPECTUS SUPPLEMENT IS MAY 5, 1998

the Prospectus. The Company may amend or supplement the Prospectus and this
Prospectus Supplement from time to time to update the disclosure set forth

Supplement, the name of each of the Selling Stockholders, the number of Shares

by the Prospectus and this Prospectus Supplement, and the number and percentage

___________________
(1) The number and percentage of shares beneficially owned is determined in
accordance with Rule 13d-3 of the Exchange Act, and the information is not
necessarily indicative of beneficial ownership for any other purpose. Under
such rule, beneficial ownership includes any shares as to which the
individual has sole or shared voting power or investment power and also any
shares which the individual has the right to acquire within 60 days of the
date of the filing of the Registration Statement through the exercise of
any stock option or other right. Unless otherwise indicated in the
footnotes, each person has sole voting and investment power (or shares such
powers with his or her spouse) with respect to the shares shown as
beneficially owned.
(2) Does not include an aggregate of 530,366 shares of Common Stock
beneficially owned by the Selling Stockholders that have been deposited in
escrow funds pursuant to the Reorganization Agreement in accordance with
certain obligations of the Selling Stockholders thereunder (the "Escrowed
Shares"). The Escrowed Shares will be available to compensate the Company
for certain losses (the "Losses") incurred by it as a result of breaches
by KIVA of various provisions in the Reorganization Agreement. The
remaining Escrowed Shares, if any, after satisfaction of any claims by the
Company against KIVA relating to Losses will be released from the escrow
funds on December 1, 1998. The Escrowed Shares have been included in the
total number of shares registered by this Registration Statement, but they
are not included in this column of the table. An amended prospectus will
be filed to reflect any change in the number of shares that the individual
Selling Stockholders may offer as a result of the release of the Escrowed
Shares.

Shares, if any.
