The North Fork Malheur River is a 59-mile (95 km) tributary of the Malheur River in eastern Oregon in the United States. Rising in Big Cow Burn in the Blue Mountains, it flows generally south to join the larger river at Juntura. The upper 25.5 miles (41.0 km) of the river have been designated Wild and Scenic. This part of the river basin offers camping, hiking, and fishing opportunities in a remote forest setting. The lower river passes through Beulah Reservoir, which stores water for irrigation and has facilities for boaters.
