Encino (Spanish for evergreen or holm oak) is an affluent district in the city of Los Angeles, California, United States. Specifically, it is located in the central portion of the southern San Fernando Valley and on the north slope of the Santa Monica Mountains. It derives its name from the Rancho Los Encinos (Ranch of the Evergreens), a parcel of land given to three Mission Indians by the Mexican government following its secularization of the California missions beginning in 1834. Rancho Encino was established in 1845. The portion of the Los Angeles River that runs through the Encino area is one of only two unpaved areas necessitated by the high water table. The original aquifer that fed the city of Los Angeles is the one located below Encino.
