Maryland Route 471 (MD 471) is a state highway in the U.S. state of Maryland. Known as Indian Bridge Road, the state highway runs 1.01 miles (1.63 km) from Maryland Route 5 north to a crossing of the St. Marys River within Great Mills. MD 471 was constructed in two segments in the early 1930s. The second segment near Leonardtown was removed from the state highway system in the mid-1950s but returned as an extension of MD 4 in the early 1980s.
