Galena Summit is a high mountain pass in the western United States in central Idaho, at an elevation of 8,701 feet (2,652 m) above sea level.

The summit is on State Highway 75, the Sawtooth Scenic Byway,[1] and is 29 miles (47 km) northwest of Ketchum and the Sun Valley ski resort.

Prior to 1977, Highway 75 was designated U.S. Route 93,[2][3][4] which is now to the east on the former U.S. 93 alternate, through Arco and the Lost River Valley.

A little more than one mile (1.6 km) west of the summit is Galena Overlook, a scenic viewpoint at 8,400 feet (2,560 m).

[7][8] Collegiate alpine ski races were held on the summit in late 1947, due to a lack of snow at Sun Valley, and supplies were dropped in by airplane.
