Mandayam Parthasarathi Tirumal Acharya (15 April 1887 – 1954) was an Indian nationalist, communist and anarchist who was among the founding members of the Communist Party of India (Tashkent group). In a long political and activist life, Acharya was at various times associated with India House in London and the Hindu-German Conspiracy during World War I when, as a key functionary of the Berlin Committee, he along with Har Dayal sought to establish the Indian Volunteer Corps with Indian prisoners of war from the battlefields of Mesopotamia and Europe. Acharya subsequently moved in 1919 after the end of the war to the Soviet Union, where he was one of the founding members of the Communist Party of India at Tashkent. However, disappointed with the Communist International, Acharya returned to Europe in the 1920s where he was involved with the League against Imperialism and subsequently was involved with the international anarchist movement.
