The Karelo-Finnish Soviet Socialist Republic (Karelo-Finnish SSR; Finnish:  Karjalais-suomalainen sosialistinen neuvostotasavalta ; Russian: Каре́ло-Фи́нская Сове́тская Социалисти́ческая Респу́блика, tr. Karelo-Finskaya Sovetskaya Sotsialisticheskaya Respublika), also called Soviet Karelia or simply known as Karelia, was a republic of the Soviet Union. It existed from 1940 until it was made part of the Russian SFSR in 1956 as the Karelian Autonomous Soviet Socialist Republic. The latter became the Republic of Karelia, a federal subject of Russia, on November 13, 1991.

The Karelo-Finnish Soviet Socialist Republic was established by the Soviet government on March 31, 1940 by merging the KASSR with the Finnish Democratic Republic. The latter was created in territory ceded by Finland in the Winter War by the Moscow Peace Treaty, namely the Karelian Isthmus and Ladoga Karelia, including the cities of Viipuri and Sortavala.
