The Kirghiz Soviet Socialist Republic, also known as the Kyrgyz Soviet Socialist Republic or Kirgiz Soviet Socialist Republic, was one of the constituent republics of the Soviet Union (USSR) from 1936 to 1991. It was also known by the names Kyrgyzstan and Soviet Kyrgyzstan in the Kyrgyz language, and as Kirghizia and Soviet Kirghizia in the Russian language. Landlocked and mountainous, it bordered Tajikistan and China to the south, Uzbekistan to the west and Kazakhstan to the north. The Kirghiz branch of the Communist Party of the Soviet Union governed the republic from 1936 until 1990.

The Republics of the Union of Soviet Socialist Republics or the Union Republics were national-based administrative units of the Union of Soviet Socialist Republics (USSR). The Soviet Union was formed in 1922 by a treaty between the Soviet republics of Byelorussia, Russian SFSR (RSFSR), Transcaucasian Federation, and Ukraine, by which they became its constituent republics of the Union of Soviet Socialist Republics.
