Eino Abramovich Rahja (20 June 1885, Kronstadt, Russian Empire – 26 April 1936, Leningrad Soviet Union) was a Finnish-Russian revolutionary who joined the Russian Social Democratic Labour Party in 1903, becoming aligned with the party's Bolshevik faction. Rahja organized Lenin's temporary escape to Finland in the summer of 1917. During the Finnish Civil War, Rahja was one of the most capable military leaders of the Reds. After the Reds lost the war, he fled to the Russian SFSR where he lived for the rest of his life and became, for example, a commander of the army corps (komkor) in the Red army.
