The Ohlone ( oh-LOH-nee), formerly known as Costanoans (from Spanish costeño meaning 'coast dweller'), are a Native American people of the Northern California coast. The Ohlone are believed to have displaced an earlier population of Hokan-speaking residents of the area. 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 related languages. The Ohlone languages make up a sub-family of the Utian language family. Older proposals place Utian within the Penutian language phylum, while newer proposals group it as Yok-Utian.
In pre-colonial times, the Ohlone lived in more than 50 distinct landholding groups, and did not view themselves as a single unified group. They lived by hunting, fishing, and gathering, in the typical ethnographic California pattern. The members of these various bands interacted freely with one another. The Ohlone people practiced the Kuksu religion. Prior to the Gold Rush, the northern California region was one of the most densely populated regions north of Mexico.
