Deserters Peak is a mountain summit in British Columbia, Canada.

It is situated along the east side of the Rocky Mountain Trench near the northern end of Williston Lake.

Topographic relief is significant as the summit rises approximately 1,600 meters (5,250 ft) above the Finlay River in 5.5 km (3.4 mi).

The mountain's toponym was officially adopted June 4, 1953, by the Geographical Names Board of Canada.

[5] The canyon's name refers to two men in Samuel Black's 1824 exploration party who decamped (deserted) at this location on May 28 during an expedition to find the headwaters of the Finlay River.
