attorney-in-fact to:


(1)	execute for and on behalf of the undersigned, in the undersigned's capacity
as an officer and/or director of Blackstone Group Management L.L.C., a Delaware
limited liability company (the "General Partner") and the general partner of The
Blackstone Group L.P. (the "Partnership"), Forms
3, 4, and 5 in accordance with Section 16(a) of the U.S. Securities Exchange Act
of 1934, as amended, and the rules thereunder;


(2)	do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete and execute any such Form 3, 4, or 5,
complete and execute any amendment or amendments thereto, and timely file such
form with the U.S. Securities and Exchange Commission and any stock exchange or
similar authority; and


(3)	take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of the
undersigned pursuant to this Power of Attorney shall be in such form and shall

      The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers

security or derivative security relating to the Partnership (whether or not
issued by the Partnership), ceases to be subject to those requirements, unless
