Riga Ghetto was a small area in Maskavas Forštate, a neighbourhood of Riga, Latvia, where Nazis forced Jews from Latvia, and later from Germany, to live during World War II. On October 25, 1941, the Nazis relocated all Jews from Riga and its vicinity to the ghetto and its non-Jewish inhabitants were evicted. Most Latvian Jews were killed on November 30 or December 8, 1941, in the Rumbula massacre. The Nazis transported a large number of German Jews to the ghetto; most of them were later killed in massacres.
