Party of Revolutionary Communism (in Russian: Партия революционного коммунизма) was a political party in Russia. It was formed by a Narodnik group which broke away from the Left Socialist-Revolutionaries after the latter's mutiny in July 1918. In September 1918, they constituted themselves as a party at a congress in Moscow. The party favoured co-operation with the Russian Communist Party (bolsheviks), and pledged support for Soviet power.
