The Williams River is a tributary, about 21 miles (34 km) long, of the South Fork Coos River in the U.S. state of Oregon. Formed by the confluence of Lost Creek and Little Cow Creek, it begins in western Douglas County near the Coos County line and flows generally northwest through the Southern Oregon Coast Range. In eastern Coos County, it joins Tioga Creek to form the South Fork Coos River about 32 miles (51 km) from its confluence with the Millicoma River.[2]
