Ochoco Creek is a 30-mile (48 km) tributary of the Crooked River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, it arises in the Ochoco National Forest in Wheeler County and flows generally southwest and west for most of its length through Crook County to slightly northwest of Prineville.

The Crooked River is a tributary, 125 miles (201 km) long, of the Deschutes River in the U.S. state of Oregon. The river begins at the confluence of the South Fork Crooked River and Beaver Creek. Of the two tributaries, the South Fork Crooked River is the larger and is sometimes considered part of the Crooked River proper. A variant name of the South Fork Crooked River is simply "Crooked River". The Deschutes River flows north into the Columbia River.
