The Indian Bar Trail Shelter in Mount Rainier National Park is a rustic shelter on the Wonderland Trail, built by the Civilian Conservation Corps in 1940. The shelter features stone walls and a log roof structure, to a design by the National Park Service Branch of Plans and Design, under the supervision of Edwin A. Nickel. Measuring about 23 feet (7.0 m) by 26 feet (7.9 m), it is one of two CCC shelters remaining on the trail, with the earlier Summerland Trail Shelter. The Indian Bar shelter features a stone fireplace, and replaced an earlier ranger-built shelter.
The shelter was listed on the National Register of Historic Places on March 13, 1991. It is part of the Mount Rainier National Historic Landmark District, which encompasses the entire park and which recognizes the park's inventory of Park Service-designed rustic architecture.
