Mount Washburn is a mountain in Yellowstone National Park, in the U.S. state of Wyoming, elevation 10,243 ft. Mount Washburn was named for former Civil War general and U.S. Congressman Henry D. Washburn, who was the surveyor general of Montana after the war. Views from the summit include much of the northern section of Yellowstone National Park and on clear days, the Teton Range is also visible. The mountain trails are some of the most frequented in the park, so summer hikes can be crowded. With an altitude gain of 1,393 feet (424 m) in 3 miles (4.8 km), the hike from Dunraven Pass to the summit is moderate. Another trail which climbs 1,491 feet (454 m) in only 2.25 miles (3.6 km) starts from the Chittenden parking area. One of three active fire lookout towers in Yellowstone is located on the summit.
