Sheep Mountain is a 10,608-foot (3,233-metre) summit in Park County, Montana, United States.

Topographic relief is significant as the summit rises approximately 1,650 feet (503 meters) above Fisher Creek in one mile (1.6 km).

The area from Cooke City to Sheep Mountain offers some of the finest backcountry snowmobiling in the country.

[5] The mountain's toponym has been officially adopted by the United States Board on Geographic Names.
