The Silver Line is a rapid transit line of the Washington Metro system, consisting of 34 stations in Loudoun County, Fairfax County and Arlington County, Virginia, Washington, D.C., and Prince George's County, Maryland. The Silver Line runs from Ashburn in Virginia to Downtown Largo in Maryland. Five stations, from both lines' eastern terminus at Downtown Largo to Benning Road, are shared with the Blue Line alone; thirteen stations, from Stadium–Armory to Rosslyn, with both the Orange Line and Blue Lines; and five stations from Court House to East Falls Church with the Orange Line alone. Only the five stations of Phase 1, which began service on July 26, 2014, and the six stations of Phase 2, which began service on November 15, 2022, are exclusive to the Silver Line.

The 11.7-mile (18.8 km) portion of the Silver Line between its split from the Orange Line and Wiehle–Reston East is entirely in Fairfax County, Virginia and was constructed as Phase 1 of the Dulles Corridor Metrorail Project.^[1] Phase 2 expanded the line another 11.5 miles (18.5 km) to Ashburn in Loudoun County via Dulles International Airport. The $6.8 billion 41.1-mile-long (66.1 km) Silver Line is Metro's largest expansion by route mileage since its inception in 1976.^[2]^[3]
