Adolf Warski, born Jerzy Adolf Warszawski (April 20, 1868, Warsaw – July 9, 1937, Moscow), was a leader and theoretician of the Polish communist movement.
He was active in the working class movement from 1889, becoming a member of the executive of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), and a member of the Communist Party of Poland (KPP) from 1918. He held positions in the KPP's Central Committee (1919-29) and Politburo (1923-29, with an interruption), and lived in the Soviet Union from 1929 until his death.
An opponent of the Stalinisation of the KPP and of the Communist International, Warski was arrested during the Great Purge, in early 1937, and executed. He was fully rehabilitated in 1956, during the De-Stalinization process that followed Joseph Stalin's death, and the Szczecin shipyard, Stocznia Szczecińska Nowa, was renamed in his honor (Stoczni im. Adolfa Warskiego) by the authorities of the People's Republic of Poland.
