The Middle Fork Owyhee River is a tributary of the North Fork Owyhee River in Malheur County, Oregon, and Owyhee County, Idaho, in the United States. It forms along Juniper Mountain, south of the Owyhee Mountains in Idaho. From its headwaters, it flows southwest then curves northwest to and beyond the Idaho–Oregon border, then turns north to meet the North Fork at Three Forks, Oregon. The confluence is less than a mile upstream from the North Fork's confluence with the Owyhee River. Below Three Forks, the main stem Owyhee flows 161 miles (259 km) to empty into the Snake River.
