George Washington Memorial Parkway in the context of "National Mall and Memorial Parks"

Potomac Yard station is a Washington Metro station in Alexandria, Virginia, United States. It is operated by the Washington Metropolitan Area Transit Authority (WMATA), serving both the Blue and Yellow Lines, and opened on May 19, 2023. It is located at Alexandria's 7.5-million-square-foot (700,000 m) Potomac Yard mixed-use development bounded by Richmond Highway (U.S. Route 1) and the George Washington Memorial Parkway. It is the second infill station to be added to the Washington Metro system, after NoMa–Gallaudet U in 2004. It was constructed on the site of Potomac Yard, a former railroad freight yard.

Potomac Yard is a neighborhood in Northern Virginia that straddles southeastern Arlington County and northeastern Alexandria, Virginia, located principally in the area between U.S. Route 1 and the Washington Metro Blue Line /Yellow Line tracks, or the George Washington Memorial Parkway, depending on the definition used. The area was home to (and takes its name from) what was once one of the busiest rail yards on the Eastern Seaboard of the United States. The "Potomac Yard" name is also used to refer to several developments in the area, especially the Potomac Yard Center power center and a Washington Metro station.

In 2018, Amazon.com, Inc. announced plans to locate part of its "HQ2" second headquarters project in Northern Virginia, specifically in the newly re-branded cross-jurisdictional neighborhood of National Landing, which local and state officials said would include Potomac Yard as well as nearby parts of southern Arlington, including the Crystal City neighborhood that will be the hub of the HQ2 development. Amazon initially planned to split HQ2 between National Landing and Long Island City, New York, but opposition from New York officials led Amazon to cancel that portion of the project, leaving National Landing as the only HQ2 site.
