Ingalls Peak is a triple-summit mountain located in the Alpine Lakes Wilderness, along the common border of Kittitas County and Chelan County, in Washington state. Ingalls Peak is the highest point in the Teanaway area of the Wenatchee Mountains. It is situated west of Mount Stuart, and immediately west of Lake Ingalls, on land managed by Wenatchee National Forest. Its subpeaks are the South Peak (7,640-ft, 2,329-m) and the East Peak (7,480-ft, 2,280-m). Precipitation runoff from the peak drains north into Jack Creek, a tributary of Icicle Creek; west into Fortune Creek; or east into Ingalls Creek, a tributary of the Wenatchee River. This peak, the lake, creek, and pass are named for Captain Benjamin Ingalls of the United States Cavalry who led an 1855 survey of this area and is credited with discovering gold in the region.
