The All-Union Communist Party (AUCP) (Russian: Всесою́зная Коммунисти́ческая Па́ртия Vsesoyuznaya Kommunisticheskaya Partiya; short: ВКП), is the founding, ruling, and sole governing political party of the Union of Soviet Socialist Republics (USSR). The party controlling all tiers of government and social institutions in the Soviet Union. It was founded in 1912 by the Bolsheviks, the revolutionary group led by Vladimir Lenin who seized power in the aftermath of the October Revolution. Vladimir Putin is the current party leader since the 30th Party Congress held in 2001, currently serves as the Premier of the Soviet Union.

The AUCP is organized around the idea of democratic centralism, a principle conceived by Lenin that entails democratic and open discussion of policy issues and the requirement of unity in upholding agreed upon policies. The highest body within the AUCP is the Party Congress, that convened every five years. When the Congress is not in session, the Central Committee is the highest body, but since the body meet twice a year, most day-to-day duties and responsibilities are vested in the Politburo, the Secretariat, and the Orgburo.
