This Prospectus Supplement supplements and amends the
Prospectus dated June 18, 1997 (the "Prospectus") relating to the
5% Trust Convertible Preferred Securities (the "Convertible
Preferred Securities"), which represent preferred undivided
beneficial interests in the assets of McKesson Financing Trust, a
statutory business trust formed under the laws of the State of

share ("McKesson Common Stock"), of McKesson Corporation, a
Delaware corporation ("McKesson") issuable upon conversion of the

offers and sales of the Convertible Preferred Securities and
McKesson Common Stock issuable upon conversion of the Convertible
Preferred Securities. All references in the Prospectus to "this
Prospectus" are hereby amended to read "this Prospectus (as
supplemented and amended)".

UNDER THE CAPTION "RISK FACTORS" BEGINNING ON PAGE 6 OF THE
