Giant Forest Museum, Natural history museum in Sequoia National Park, United States

The Giant Forest Museum occupies the Giant Forest Market, a building designed by Gilbert Stanley Underwood in the National Park Service rustic style and constructed in 1928–1929. It stands in the Giant Forest of Sequoia National Park, Tulare County, California, and is run by the National Park Service. Its exhibits cover the area's giant sequoias, meadows and human history, with interactive displays on the park's natural history and ecology.

The building was designed by Gilbert Stanley Underwood in the National Park Service rustic style and erected in 1928–1929 as the Giant Forest Market, a shop. It is a contributing property to the Giant Forest Village-Camp Kaweah historic district, listed on the National Register of Historic Places on 22 May 1978. Renovation began in 1999 and it reopened as a museum in summer 2001, managed by the National Park Service.

The museum stands in the Giant Forest of Sequoia National Park, in Tulare County, California. From it, Round Meadow is an easy one-mile stroll, and trails lead into the Hazelwood area to the Hazelwood Tree. The building serves as a visitor center, so exhibits and orientation come before the walks.

The building was originally a market building and was later completely transformed to house exhibits and educational spaces. This adaptive reuse shows how historic structures in the park are repurposed for new functions while retaining their basic form.
