Dead Horse Peak is a 12,642-foot mountain on the crest of Utah’s Uinta Mountains in the Rocky Mountains, straddling Duchesne and Summit counties within the High Uintas Wilderness. Managed by Ashley National Forest and Uinta-Wasatch-Cache National Forest, it ranks as Utah’s 50th-highest summit and rises sharply above the surrounding terrain, especially near Dead Horse Lake. Its waters drain north to the Blacks Fork and south to Rock Creek, part of the Duchesne River system. The area has a subarctic climate with tundra on the highest slopes. Although widely used, the name remains unofficial and is absent from USGS maps under wilderness naming policy.
