Bell Mountain Wilderness is a federally protected wilderness area in southeastern Missouri, in the Saint Francois Mountains of the northeastern Ozarks, managed within Mark Twain National Forest south of Potosi. Designated by Congress in 1980, it covers 9,143 acres and is one of eight protected wilderness areas in the state. Named for Bell Mountain, its highest point, and ultimately for pioneer settler Henry Bell, the area is known for rugged terrain, relatively undisturbed forest, old-growth settings, and streams including Joes Creek and Shut-in Creek. It supports hiking, wildlife viewing, and connects with the broader protected landscape of nearby state parks.
