The North Fork Owyhee River is a tributary, about 30 miles (48 km) long, of the Owyhee River in Malheur County, Oregon, and Owyhee County, Idaho, in the United States. It begins on the east flank of the Owyhee Mountains in Idaho and flows generally southwest to meet the main stem at Three Forks, Oregon, 161 miles (259 km) above the confluence of the larger river with the Snake River.

Wild and scenic designation
The upper 20.8 miles (33.5 km) of the North Fork, from the upstream boundary of the North Fork Owyhee Wilderness to the Idaho–Oregon border, are part of the National Wild and Scenic Rivers System. Of this total, 15.1 miles (24.3 km) are classified as wild and the remaining 5.7 miles (9.2 km) are "recreational". The lower 9.6 miles (15.4 km) of the North Fork, from the Idaho–Oregon border to the main stem, is also classified as wild. It flows through a deep canyon rimmed with basalt. The Bureau of Land Management oversees the land along the river in both states.
Camping
The BLM operates North Fork Campground, about 27 miles (43 km) southeast of Jordan Valley, Oregon. Amenities include seven primitive campsites, picnic tables, fire grates, and a vault toilet but no drinking water.
Wilderness
In 2009, the United States Congress designated the wilderness, which covers about 43,000 acres (17,000 ha) in the Idaho portion of the North Fork watershed. It extends from the headwaters in Idaho almost to the border with Oregon. Managed by the BLM, it includes river canyons that are more than 1,000 feet (300 m) deep as well as large expanses of plateau. The wilderness is home to sage grouse, pronghorn, bighorn sheep, rare plants, and many other species. The wilderness is about 80 miles (130 km) southwest of Boise.
