The Ohlone people, also known as the Costanoan, are a Native American people of the central California coast. When Spanish explorers and missionaries arrived in the late 18th century, the Ohlone inhabited the area along the coast from San Francisco Bay through Monterey Bay to the lower Salinas Valley. At that time they spoke a variety of languages, the Ohlone languages, belonging to the Costanoan sub-family of the Utian language family, which itself belongs to the proposed Penutian language phylum or stock. The term 'Ohlone' has been used in place of 'Costanoan' since the 1970s by some descendant groups and by most ethnographers, historians, and writers of popular literature.
