Sun Camp Fireguard Cabin, Log cabin in Glacier County, Montana.

The Sun Camp Fireguard Cabin was a log building near the mouth of Baring Creek in Glacier National Park, built in 1935 by contractor Harry E. Doverspike to specifications from the NPS Division of Landscape Architecture. It was the last surviving structure of the Sun Camp Ranger Station complex, which once included a ranger station, barn and woodshed. Its entry was placed in the center wall, the only apparent deviation from the standard plan. It had no indoor plumbing, and a wood stove's pipe passed through the back log wall to a stone chimney.

The cabin was built in 1935 by contractor Harry E. Doverspike as part of the Sun Camp Ranger Station complex within Glacier National Park. It served the park's fire management and forest protection efforts during that era.

The cabin's name links it to Sun Camp, the ranger station complex near the mouth of Baring Creek whose ranger station, barn and woodshed have all disappeared; the fireguard cabin was the last survivor. Its entry sits in the centre of a wall, the one visible departure from the NPS Division of Landscape Architecture's standard cabin plans. It was listed on the National Register of Historic Places on 1 July 1999.

The cabin was originally built with minimal amenities and relied on wood-burning heat without running water. Visitors approaching ranger station historical sites should understand these were functional work spaces rather than dwellings.

The cabin was listed on the National Register of Historic Places on July 1, 1999, sixteen years before the Reynolds Creek Wildfire destroyed it on July 22, 2015. It was the last surviving building of the Sun Camp Ranger Station complex, which once also held a ranger station, a barn and a woodshed near the mouth of Baring Creek.
