The Roger Pryor Pioneer Backcountry is a 60,000-acre (243 km2) area of private land that is managed by the Missouri Department of Natural Resources for hiking and backpacking by the public. The land is part of the largest private forest in the state, the Pioneer Forest, owned by the L-A-D Foundation, an endowment of the late Missouri timber magnate, conservationist, and philanthropist Leo Drey (1917–2015).
