The Powder River is a tributary of the Snake River, approximately 153 miles (246 km) long, in northeast Oregon in the United States. It drains an area of the Columbia Plateau on the eastern side of the Blue Mountains. It flows almost entirely within Baker County but downstream of the city of North Powder forms part of the border between Baker County and Union County.
