The work is devoted to investigation of sexual dimorphism and interpopulation variability of pond frog on the territory of Ukraine. The difference between males of the populations from Chernihiv, Zhytomyr and Vinnytsia regions was found. Sp. oc., H., C. int. and Cr. a. c features were taken into consideration. The interpopulation differences for multiple traits in females are slightly higher than in males. Sexual dimorphism of pond frog was established by 9 characteristics: L., L. c., Lt c. tym, L. tym., Sp. o. ˝., M., D.p.m., T., Lt. ­es. Males and females from Chernihiv population are differed by features which are widely used in the taxonomy of green frogs (L./, D.p.p./, T./, F./T., L.o./L.tym).
