North Fork Crooked River

The North Fork Crooked River is a tributary, 46 mi long, of the Crooked River in the U.S. state of Oregon. Beginning in the Ochoco National Forest and the Ochoco Mountains east of Prineville, it flows north, then east, then south-southwest to meet the larger stream between Post and Paulina. The confluence is 111 mi upstream of where the Crooked River flows into the Deschutes River.

In 1988, Congress added a large fraction of the river to the National Wild and Scenic Rivers System. About 12 mi were designated "wild", about 8 mi "scenic", and about 13 mi "recreational". About 8 mi of the upper river flowing through Big Summit Prairie was excluded from the Wild Rivers designation. It is private land used as livestock pasture.
