The Washington Metro (commonly called Metro and branded Metrorail) is a rapid transit system serving Washington, D.C. and neighboring communities in Maryland and Virginia, both inside and outside the Capital Beltway.

Like most rapid transit systems in the United States, ridership has not recovered from COVID-19 era collapses, falling from an average weekday ridership of 764,300 in the first quarter of 2015 to 519,700 in the fourth quarter of 2024. Nevertheless, the Washington Metro remains the second-busiest rapid transit system in the United States behind the New York City Subway. , the system has 98 active stations on six lines with of tracks.

The Washington Metro system was conceived as an alternative to constructing a large freeway system throughout the Washington, D.C. area. It was partially financed with funds originally dedicated to highway construction. Construction began in 1969, and in 1976 the first section of the Metro system opened along the Red Line between the and stations in Washington, D.C. Throughout the 1970s and 1980s, more stations were opened in the city and the suburban communities of Arlington County, the City of Alexandria, and Fairfax County in Virginia as well as Montgomery and Prince George's Counties in Maryland. By 1991, five rail lines were open: the Red, Orange, Yellow, Green, and Blue Lines. The system, as originally planned, was completed in 2001 with the extension of the Green Line to . In 2004, three stations were opened: an extension of the Blue Line to the and stations and the first infill station, . The Silver Line opened in two phases, adding five stations in 2014 and six in 2022. On the Yellow and Blue Lines, an additional infill station at opened on May 19, 2023.

Nine Metrorail stations are officially designated transfer stations, although other intermediate stations also allow passengers to transfer between lines. Four of these stations have separate, perpendicular upper and lower levels, which opened at different times. Two other transfer stations, and , have parallel stacked platforms. Ten stations are termini (stations at the end of lines); several other non-terminus stations are used to short turn trains in regular service.

The busiest station in the system in 2023 was Metro Center, with more than 3.9 million passenger entries over the course of the year. Rosslyn was the busiest station in Virginia, while Silver Spring was the busiest in Maryland. The system's 10 busiest stations are all located in Washington.
