Middletown Rancheria is a government administration company based out of 22223 Highway 29, Middletown, California, United States. The Middletown Rancheria of Pomo Indians of California (the "Tribe") was established with the purchase of one hundred eight (108) acres of land, initiated by members of the small Tribe in July of 1910. The Tribe was appropriated by the Congressional Act for California landless Indians in 1906. The original ancestors of the Middletown Rancheria, also known as Pomo and Lake Miwok Indians, found themselves landless and homeless during the 1800's, and new corners settled in the area of Middletown and throughout Lake County.
