Willow Creek is a tributary, about 26 miles (42 km) long, of the Deschutes River in central Oregon in the United States. Arising near Foley Butte in the western Ochoco Mountains in Crook County, it flows generally northwest into Jefferson County and through the Crooked River National Grassland. The creek continues through the city of Madras and becomes the dividing line between two plateaus, Agency Plains and Little Agency Plains. It then enters the Deschutes above Pelton Dam and its impoundment, Lake Simtustus, about 105 miles (169 km) from the river's confluence with the Columbia River.
