Nationals Park is a baseball park located along the Anacostia River in the Navy Yard neighborhood of Washington, D.C. It is the home ballpark for the Washington Nationals, the city's Major League Baseball franchise. When the Nationals franchise relocated to Washington, D.C., they temporarily played at RFK Stadium until Nationals Park was completed.
It is the first LEED-certified green major professional sports stadium in the United States. The facility hosted the 2008 season's first game (in North America), when the Nationals hosted the Atlanta Braves on March 30, 2008. The first game played there was a collegiate baseball game.
