Couchville Cedar Glade State Natural Area is a 140-acre protected area in Davidson and Wilson counties, Tennessee, preserving one of the most undisturbed cedar glades left in Middle Tennessee. Designated a Class II Natural-Scientific state natural area, it adjoins Long Hunter State Park along its western edge. The glade features broad stretches of bare rock interrupted by Eastern red cedars, grasses, wildflowers, and wildlife adapted to this unusual habitat. Notable plant life includes the Tennessee coneflower, Echinacea tennesseensis. A mile-long hiking trail loops through the reserve, whose name also preserves the memory of the nearby lost community of Couchville.
