Dem'ianiv Laz (Ukrainian: Дем'янів Лаз, Polish: Demianów Łaz) is a mass burial site of victims of the Soviet extrajudicial killings committed in the wake of the Nazi German takeover of Stanisławów (modern Ivano-Frankivsk, Ukraine) in 1941. At least 524 Polish captives (including 150 women with dozens of children) were shot by the NKVD and buried in several mass graves dug by the prisoners themselves in a small gorge outside of the city.
