Fair Glacier, Mountain glacier at Apache Peak in Roosevelt National Forest, Colorado, United States

Fair Glacier is an alpine glacier immediately west of Apache Peak in Roosevelt National Forest, Colorado, lying just west of the Continental Divide on the opposite side from Isabelle Glacier. It sits at about 3,584 metres on a ridge, with Indian Peaks rising roughly 1.1 km to the northeast.

Photographs from 1910 first documented this glacier and provided early records of its structure. Those early images helped establish its place within the Indian Peaks range.

Fair Glacier sits on the Continental Divide's western side, directly opposite Isabelle Glacier, which drains east toward the Isabelle Glacier Trail. Climbers based at Brainard Lake Recreation Area use the glacier as a snow and ice route on Apache Peak, and the surrounding Indian Peaks Wilderness sees few visitors compared with the lakes below.

Reaching this glacier requires hiking from Long Lake Trailhead through Brainard Lake Recreational Area, passing several mountain lakes along the way. The route is lengthy and demands good fitness and proper mountain gear.

Fair Glacier sits at 3,584 metres on the Grand County side of the Continental Divide, directly opposite Isabelle Glacier, which drains east toward the Isabelle Basin. Indian Peaks, the higher summit above it, rises to 4,080 metres about 1.1 km to the southwest. The glacier lies within Roosevelt National Forest, roughly 16.6 km from Nederland.
