The USSR State Prize (Russian: Госуда́рственная пре́мия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on September 9, 1966. After the breakup of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works created in 1943–1944 and in June for the works of 1945. It should also not be confused with the Lenin Prize.
