The Chumash are a Native American people who historically inhabit mainly the southern coastal regions of California, in the vicinity of what is now San Luis Obispo, Santa Barbara, Ventura and Los Angeles counties, extending from Morro Bay in the north to Malibu in the south. They also occupied three of the Channel Islands: Santa Cruz, Santa Rosa and San Miguel; the smaller island of Anacapa was unihabited. Modern place names with Chumash origins include Malibu, Lompoc, Ojai, Point Mugu, Piru, Lake Castaic, and Simi Valley.
