Pilviškiai (Polish: Pilwiszki, Yiddish: פילווישאָק Pilveshok) is a town in Vilkaviškis district municipality and in Marijampolė County
In the Jewish world, it was known historically for its learned population,[1] served among others by Rabbi Yechiel Yaakov Weinberg.
In August 1941, the Jewish men of Pilviškiai district were shot. The mass murder was perpetrated by an Einsatzgruppe of Germans and Pilviškiai self-defence police unit. The victims were about 300 to 350 Jewish men and several dozen Soviet activists (including a group of girls from the Communist Youth organization).[2]
