Wintun is a name generally given to a group of Penutian-speaking Indigenous Peoples in what is now California. Traditional Wintun territory was some 250 miles (400 km) from north to south and included stretches of the flanking foothills. Four primary linguistic groupings made up the Wintun population: the northern Wintun (Wintu), the central Wintun (Nomlaki), and the two subdivisions of the southern Wintun, the Hill and River Patwin.
