The Green Line is a rapid transit line of the Washington Metro system, consisting of 21 stations in Washington, D.C., and Prince George's County, Maryland, United States. The Green Line runs from Branch Avenue, to Greenbelt, connecting the southeast suburbs to the northeast suburbs through downtown Washington, DC.

It was the last line in the original Metro plan to be constructed, with service beginning in 1991, and is one of three north–south lines through the city of Washington. The Green Line shares track with the Yellow Line from L'Enfant Plaza to Mount Vernon Square. The fully completed line was opened for service on January 13, 2001, which concluded construction of the original 101-mile Metrorail system.
