The NKVD prisoner massacre in Berezhany was a Soviet war crime conducted by the NKVD in the city of Berezhany, then in occupied Poland and now in Ukraine. Between 26 and 30 June 1941, following the German invasion of the USSR, the Soviets executed at least 174 prisoners held in the Berezhany prison. This atrocity was one of several prisoner massacres carried out by the Soviet secret police and army during the summer of 1941.
