New CCD photometry for the eclipsing binary EH Cnc was made from 2009 to 2011, and five new eclipsing times are presented. Through using the updated Wilson-Devinney code, we first deduced the photometric solution at {chi}^2^=0.9906. The results show that EH Cnc is a W-type contact binary, whose mass ratio and overcontact degree are q=2.51(+/-0.02) and f=27.7%(+/-3.4%) , respectively.
