Maryland Route 311 (MD 311) is a state highway in the U.S. state of Maryland. Known for most of its length as Henderson Road, the state highway runs 6.11 miles (9.83 km) from MD 313 in Goldsboro north to MD 454 in Marydel. MD 311 was constructed in the mid-1920s. The state highway originally continued through Marydel to the Delaware state line, but was rolled back in favor of MD 454 in the mid-1940s.

MD 311 begins at an intersection with MD 313 (Oldtown Road) in the town of Goldsboro. The state highway, named Main Street, heads north, closely paralleling an unused rail line whose right of way is owned by the Maryland Department of Transportation. After intersecting MD 287 (Sandtown Road), MD 311 leaves the town of Goldsboro and the vicinity of the rail line and the highway's name changes to Henderson Road. The state highway crosses Broadway Branch before rejoining the rail line immediately before the intersection with River Bridge Road, where the highway enters the town of Henderson. After leaving Henderson, MD 311 veers away from the rail line and crosses Cold Spring Branch. The state highway passes through a mix of farms and forests as it approaches the town of Marydel. Within the town, the state highway becomes Halltown Road and intersects Main Street, which is unsigned MD 821, shortly before reaching its northern terminus at MD 454 (Crown Stone Road/Halltown Road).
