The Russian Liberation Army was a collaborationist formation, primarily composed of Russians, that fought under German command during World War II. The army was led by Andrey Vlasov, a Red Army general who had defected, and members of the army are often referred to as Vlasovtsy (Власовцы). In 1944, it became known as the Armed Forces of the Committee for the Liberation of the Peoples of Russia.

A large number of Soviet citizens of various ethnicities collaborated with Nazi Germany during World War II. It is estimated that the number of Soviet collaborators with the Nazi German military was around 1 million.
