Maryland Route 331 (MD 331) is a 28.74-mile (46.25 km) state highway on the Eastern Shore of Maryland in the United States. Signed north-south, the route runs from Vienna in Dorchester County northwest to Easton in Talbot County, intersecting U.S. Route 50 (US 50) at both ends. MD 331 is a two-lane undivided road most of its length that passes mostly through agricultural areas. The road also passes through the communities of Hurlock and Preston along the way. It encounters several routes during its journey, including MD 14 near Rhodesdale and MD 16 in the Preston area, both of which the route forms concurrencies with. In addition, the route also intersects with MD 392 and MD 307 in Hurlock and with MD 318 near Preston.

Most of present-day MD 331 was designated as part of US 213 in 1926 when the U.S. Highway System was established. By 1940, US 213 was moved to a new alignment that crossed the Choptank River at Cambridge on a bridge built in 1935 and MD 331 was designated to run from Vienna to Easton. Both ends of MD 331 have been shortened since, with the southernmost portion of MD 331 curtailed following the completion of the US 50 bypass of Vienna by the 1990s and the northern terminus of the route cut back to US 50 in 2004 when the state-maintained portion of Dover Road to Dover Street in Easton was turned over to the city.
