Mamia Orakhelashvili (Georgian: მამია ორახელაშვილი, Russian: Иван (Мамия) Дмитриевич Орахелашвили, Ivan (Mamia) Dmitrievich Orakhelashvili) (June 10, 1881 – December 11, 1937) was a Georgian Bolshevik and Soviet politician energetically involved in the revolutionary movement in Russia and Georgia.
Born in the Kutais Governorate, Imperial Russia (in present-day Georgia) in the family of a landlord, Orakhelashvili studied medicine at the University of Kharkov and St. Petersburg Military Medical Academy. He joined the Bolshevik faction of the Russian Social Democratic Labour Party in 1903 and took an active part in the 1905 uprising in Petersburg. Between 1906 and 1914 he was arrested by the Tsarist police several times.
After the 1917 Bolshevik seizure of power, Orakhelashvili chaired the Vladikavkaz Soviet. Between 1918 and 1920 he worked in the underground Bolshevik group in the Democratic Republic of Georgia, and was arrested by the Georgian government. He was released in accordance to the Moscow Treaty between Georgia and Soviet Russia (May 1920) and became chairman of the recently legalized Georgian Communist party. In February 1921, he participated in a Bolshevik diversion in southern Georgia, which was used by Vladimir Lenin’s government as a pretext for the Red Army invasion of Georgia.
