Glacier Peak is a 9,495-foot elevation (2,894 m) mountain summit located in Union County, Oregon, US.

Glacier Peak is located at the center of the Wallowa Mountains and is set within the Eagle Cap Wilderness, on land managed by Wallowa–Whitman National Forest.

Topographic relief is significant as the summit rises 3,100 feet (940 meters) above Eagle Creek in less than one mile.

On the north slope, a permanent snowfield called Benson Glacier is a relict of the Wallowa Glacier which carved the canyon of West Fork Wallowa River for almost 20 miles during the late Pleistocene.

This landform's toponym has not been officially adopted by the United States Board on Geographic Names, so it is not labelled on USGS maps, and will remain unofficial as long as the USGS policy of not adopting new toponyms in designated wilderness areas remains in effect.
