We present a photometric study of the overcontact binary AH Cnc. The CCD observations were done with the Russian-Turkish 1.5 m telescope and the light-curve was solved with the Wilson-Devinney code. The physical parameters of the components have been deduced as M-1 = 1.22 M-circle dot, M-2 = 0.20 M-circle dot, R-1 = 1.37 R-circle dot, R-2 = 0.66 R-circle dot, L-1 = 2.65 L-circle dot and L-2 = 0.63 L-circle dot from the obtained orbital parameters and the distance modules of M67. AH Cue ha's been compared with similar systems in the Hertzsprung-Russell diagram.
