Middle Owyhee 11 is a remote campsite located at Three Forks, where the North Fork, Middle Fork, and main stem of the Owyhee River converge in Malheur County, Oregon.

The site offers five designated campsites, vault restrooms, vehicle parking, and a boat launch, serving as the put-in point for Middle Owyhee rafting trips and the take-out for upper Owyhee expeditions.

Access requires high-clearance four-wheel drive via the challenging Soldier Creek Loop Road (36 miles from U. S. 95), with the final two miles being steep and rocky; hiking down from the rim is recommended if road conditions are treacherous.
