Sheep Creek Falls is a waterfall on Sheep Creek in the Wenaha–Tucannon Wilderness of southeastern Washington, within the hills of the Umatilla National Forest. Near the confluence of Sheep Creek and the Tucannon River, it stands close to the Columbia-Garfield county line. The falls are accessed from the Tucannon trailhead at the junction of the two waterways. From there, a well-maintained trail follows Sheep Creek upstream after crossing a bridge over the creek. The site lies about 55 miles east of Dayton and 28 miles south of Pomeroy, reached by Tucannon River Road, whose final stretch near Ladybug Campground is unpaved.
