Minamitama (南多摩郡, Minamitama-gun, South Tama) was a district or county (gun) of Tokyo (Metropolis/Prefecture), Japan. It was created in the early Meiji era when the old Tama District of Musashi Province was divided into four parts and split between Kanagawa and Tokyo. It lost its status as an administrative unit in the 1920s when county governments and councils were abolished across the country. As a geographical unit, it ceased to exist in 1971 when its last two remaining municipalities were promoted to independent cities.
