The Latvian Soviet Socialist Republic (; Latvian: Latvijas Padomju Sociālistiskā Republika; Russian: Латвийская Советская Социалистическая Республика, Latviyskaya Sovetskaya Sotsialisticheskaya Respublika), also known as Soviet Latvia or Latvia, was a republic of the Soviet Union.

It was established on 21 July 1940, during World War II, as a Soviet puppet state^[in the territory of the previously independent Republic of Latvia after it had been occupied on June 17, 1940 by the Soviet Army, in conformity with the terms of the 23 August 1939 Molotov–Ribbentrop Pact.

Soviet rule came to the end during the dissolution of the Soviet Union. The first freely elected parliament of the Latvian SSR passed a declaration "On the Renewal of the Independence of the Republic of Latvia" on May 4, 1990, restoring the official name of the State of Latvia as the Republic of Latvia. and restoring its former state symbols - flag and anthem. The full independence of the Republic of Latvia was restored on 21 August 1991.
