Maryland Route 237 (MD 237) is a state highway in the U.S. state of Maryland. Known as Chancellors Run Road, the route runs 2.95 miles (4.75 km) from MD 246 near Lexington Park north to MD 235 in California in St. Mary's County. MD 237, which was designated in the mid-1980s, bypasses the center of Lexington Park through the suburban area surrounding Naval Air Station Patuxent River (NAS Patuxent River). The state highway was expanded to a four-lane divided highway between 2008 and 2010 in response to increased activity at the military base.
