We present the first light curve analysis for two newly discovered W UMa eclipsing binaries in the field of the globular cluster M15. As spectroscopic observations are not available, we used the FOTEL program to obtain the light curve solution of both systems. The fundamental properties of each system are obtained. Several tests concerning values of mass ratio and effective temperatures were carried out. Independent distance moduli for each system are obtained, and the membership to the parent cluster is discussed. It is shown that W2 is a member of M15, whereas W1 is not.
