Mount Glenn is a 9,806-foot (2,989 m) elevation glaciated summit located 40 mi (64 km) northwest of Valdez in the Chugach Mountains of the U.S. state of Alaska.

This remote mountain north of Prince William Sound, set on land managed by Chugach National Forest, is situated 6.44 mi (10 km) west-southwest of Mount Witherspoon, and 9.34 mi (15 km) west of Mount Einstein.

[4] The mountain's name was applied in 1911 by Lawrence Martin, and officially adopted in 1930 by the U.S. Board on Geographic Names to honor Edwin Forbes Glenn (1857–1926), an Army officer who explored this College Fjord area in 1898.

[7] Weather systems coming off the Gulf of Alaska are forced upwards by the Chugach Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall.

This climate supports the Harvard and Yale Glaciers surrounding this mountain.
