                                  401(k) Smart Plan
                                  Registration Statement on Form S-8

Ladies and Gentlemen:

         We have represented Publix Super Markets, Inc. (the "Company") in
connection with the Company's Registration Statement on Form S-8 (the "S-8
Registration Statement") relating to the proposed public offering by the
Company (the "Offering) of up to 10,000,000 shares of the Company's Common
Stock under the Company's 401(k) SMART Plan, the Company's 401(k) SMART Trust
Number 1 and the Company's 401(k) SMART Trust Number 2 (collectively the
"Plan").  This opinion is being provided as Exhibit 5 to the S-8 Registration
Statement.

         In our capacity as counsel to the Company in connection with the
Registration Statement and the Offering, we have examined and are familiar
with: (1) the Company's Articles of Incorporation and bylaws, as currently in
effect, (2) the Plan, (3) the S-8 Registration Statement and (4) such other
corporate records and documents and instruments as in our opinion are necessary
or relevant as the basis for the opinions expressed below.

         As to various questions of fact material to our opinion, we have
relied without independent investigation on statements or certificates of
officials and representatives of the Company, the Department of State of the
State of Florida and others.  In all such examinations, we have assumed the
genuineness of all signatures on original and certified documents and the
conformity to original and certified documents of all copies submitted to us as
conformed, photostatic or other exact copies.

         We express no opinion as to the law of any jurisdiction other than of
the State of Florida and the Federal laws of the United States of America.

         Based upon and in reliance on the foregoing, we are of the opinion
that:

         1.      The Company is a duly organized and existing corporation under
the laws of the State of Florida and its status is active.

                          shall have been offered as contemplated in the Plan;

                 c.       when certain approvals and ratifications by the
                          Company's Board of Directors relating to the Plan and

                 e.       the certificates representing such shares shall have
                          been duly executed, counter-signed and issued by or
                          on behalf of the Company,

stock of the Company.

         This firm hereby consents to the filing of this opinion as an Exhibit
