The Francis Beidler Forest is an Audubon wildlife sanctuary in Four Holes Swamp, a blackwater creek system in South Carolina, United States. It consists of over 18,000 acres (73 km²) of mainly bald cypress and tupelo gum hardwood forest and swamp with approximately 1,800 acres (7 km2) of old-growth forest. It is the largest virgin stand of cypress-tupelo forest in the world, with some Bald Cypress trees over 1,000 years old. It is a favorite haunt of birdwatchers and is used for biological research projects by area schools.

The preserve was established to protect one of only two stands of old-growth forest in South Carolina. On May 30, 2008 the forest was designated a Ramsar Wetland of International Importance. It was designated a National Natural Landmark in 1979. In 2020, Four Holes Swamp was designated a site on the National Park Service's Underground Railroad - Network to Freedom program.
