The Morongo Band of Mission Indians is a federally recognized tribe. The main tribal groups are Cahuilla and Serrano. Tribal members also include Cupeño, Luiseño, and Chemehuevi Indians. Although many tribes in California are known as Mission Indians, some, like those at Morongo, were never a part of the Spanish Missions in California. The Morongo Reservation is located in Riverside County, California.
