COMMON SHARES OF BENEFICIAL INTEREST

This prospectus supplement supplements and amends the prospectus dated April 17, 2015, relating to the resale from time to time by certain selling shareholders of our common shares of beneficial interest that they have received or will receive in exchange for units of limited partnership interests of our operating partnership, Liberty Property Limited Partnership.

This prospectus supplement should be read in conjunction with and accompanied by the April 17, 2015 prospectus and is qualified by reference to that prospectus, except to the extent that the information in this prospectus supplement supersedes the information contained in that prospectus.

SELLING SHAREHOLDER

The selling shareholder listed in the following table may receive common shares in exchange for units of limited partnership interest in our operating partnership that have been pledged to the selling shareholder by a holder of our units as security for a loan by the selling shareholder to such unitholder.  All information regarding the number of common shares beneficially owned by the selling shareholder named in this prospectus supplement has been provided to us by the selling shareholder.

*                 Indicates less than one percent (1%).

(1)         Calculated based on 148,893,177 common shares outstanding as of February 23, 2015.  In calculating this amount for the selling shareholder named in this prospectus supplement, we treated as outstanding the number of common shares issuable in exchange for units of limited partnership interest in our operating partnership that have been pledged to the selling shareholder, but we did not include common shares issuable in exchange for any other units of limited partnership interest in our operating partnership.
