Ranger Peak, Mountain summit in Grand Teton National Park, Wyoming, United States

Ranger Peak is an 11,360-foot (3,460 m) summit in the northern Teton Range of Grand Teton National Park, Wyoming. It stands slightly northwest of Colter Bay Village, across Jackson Lake, with Colter Canyon to the north and Waterfalls Canyon immediately southeast. Its top rises more than 4,500 feet (1,400 m) above Jackson Lake, and no maintained trails lead to it.

The peak received its name during early mapping efforts of Grand Teton National Park in the early 1900s. The name reflects the role of park rangers in exploring and documenting this mountain region.

The peak is named on maps of the northern Teton Range, and its slopes are known among local skiers for the couloir where Chris Onufer and Steve Romeo, both Jackson residents and expert skiers, died in an avalanche on March 7, 2012. No maintained trails lead to the summit; access is by off-trail hiking and scrambling.
