Maryland Route 5 (MD 5) is a 74.34-mile (119.64 km) long state highway that runs north–south in the U.S. state of Maryland. The highway runs from Point Lookout in St. Mary's County north to the Washington, D.C. border in Suitland, Prince George's County. MD 5 begins as the two-lane undivided Point Lookout Road which runs from Point Lookout, St. Mary's County, to an intersection with MD 235 in the northern part of the county. Point Lookout Road passes through rural areas as well as the county seat of Leonardtown. After the MD 235 intersection, the route becomes the four-lane divided Three Notch Road and continues into Charles County, where it becomes Leonardtown Road. Here, the route bypasses Hughesville and continues north toward the Waldorf area, which it bypasses to the east on Mattawoma
