Heaven's Peak Fire Lookout, Fire lookout tower in Glacier National Park, Montana, United States.

Heaven's Peak Fire Lookout is a one-story timber building with a flat, overhanging roof, set on a stone foundation in Glacier National Park, Flathead County, Montana. Cables anchor the roof to the foundation. It is one of a chain of staffed fire lookout posts in the park.

The lookout was planned in 1940 as a Public Works Administration project, with local contractor Ole Norden engaged to build it. Norden could not carry out the work, and it was finished in 1945 under a different contract. The one-story timber structure with a flat, overhanging roof was listed on the National Register of Historic Places on 19 December 1986.

The lookout is one of a chain of staffed fire lookout posts within Glacier National Park, a system for spotting fires across the backcountry. It was listed on the National Register of Historic Places on 19 December 1986, which recognized this working post as part of the park's fire-detection network.

Reaching the building requires advanced hiking skills and physical endurance for steep mountain trails. It can be spotted from certain points along Going-to-the-Sun Road where visitors can photograph it with binoculars.

The 1940 contract went to local builder Ole Norden as a Public Works Administration project, but he could not carry out the work; a different contract finally completed the lookout in 1945. The flat overhanging roof is tied to the stone foundation with cables, an anchor against mountain winds.
