The Russian State Archive of Socio-Political History (RGASPI) () is a large Russian state archive based in Moscow, which holds pre-1952 archives of the Communist Party of the Soviet Union (CPSU). It is managed by Rosarkhiv.

The archives include many of the personal papers of major Communist and Soviet leaders, including Nikolai Bukharin, Felix Dzerzhinsky, Lazar Kaganovich, Mikhail Kalinin, Lev Kamenev, Sergei Kirov, Georgy Malenkov, Anastas Mikoyan, V. M. Molotov, Georgi Plekhanov, Joseph Stalin, Leon Trotsky, and Grigory Zinoviev.
