| Abstract: | In this study we present photometric observations of the eclipsing binary KR Cyg made in 1999 and 2000. The observations of
the eclipsing binary KR Cyg have been carried out in B, V and R colours at the Ege University Observatory. A new seasonal
light curves are presented. New times of minima and ephemerides are given. Based on a statistical analysis of the times of
minima obtained by photoelectric photometry, the orbital period of the system is found to be constant. The photometric mass
ratio of the system is well determined. The corresponding light curves were analyzed by the Wilson-Devinney code.
