Maryland Route 257 (MD 257) is a state highway in the U.S. state of Maryland. Known as Rock Point Road, the state highway runs 9.75 miles (15.69 km) from MD 254 near Rock Point north to U.S. Route 301 (US 301) in Newburg. MD 257 serves the Cobb Neck of southern Charles County between the Potomac River and Wicomico River, connecting the communities of Cobb Island, Issue, Tompkinsville, and Wayside with US 301. The state highway was originally the southernmost section of MD 3, which was constructed on the peninsula in the 1910s. The portion of MD 3 south of US 301 was rebuilt and renumbered as MD 257 in the 1950s. The southern terminus of the route was cut back from Rock Point to its current location in the 1980s.
