Maryland Route 20 (MD 20) is a state highway in the U.S. state of Maryland. The highway runs 13.77 miles (22.16 km) from Beach Road and Lawton Avenue in Rock Hall east to MD 291 in Chestertown. MD 20 connects Chestertown with several villages in western Kent County, including Fairlee. The highway was designated one of the original state roads to be improved by the Maryland State Roads Commission in 1909 and was built between the mid-1910s and early 1920s. MD 20 was widened in the late 1940s and received bypasses of Fairlee and in Rock Hall in the mid-1950s and late 1950s, respectively. The highway was removed from the center of Chestertown in the mid-1980s.
