The Mount Fremont Fire Lookout is a fire lookout in the northern region of Mount Rainier National Park at an elevation above 7,000 feet (2,100 m), the highest in the park.

The building is about 14 by 14 feet (4.3 by 4.3 m), and was designed by the National Park Service Branch of Plans and designs under the supervision of Acting Chief Architect Edwin A. Nickel.

Cables secured to deadmen keep the lookout from blowing over.

The Park Service was assisted during construction by the Emergency Conservation Works Association.
