Robert F. Kennedy Memorial Stadium, commonly known as RFK Stadium and originally known as District of Columbia Stadium, is a defunct multi-purpose stadium in Washington, D.C. It is located about two miles (3 km) due east of the U.S. Capitol building, near the west bank of the Anacostia River and next to the D.C. Armory. Opened in 1961, it was owned by the federal government until 1986.

A multi-purpose stadium is a type of stadium designed to be easily used for multiple types of events. While any stadium could potentially host more than one type of sport or event, this concept usually refers to a specific design philosophy that stresses multifunctionality over specificity. It is used most commonly in Canada and the United States, where the two most popular outdoor team sports—Canadian football or American football and baseball—require radically different facilities. Football uses a rectangular field, while baseball is played on a diamond with a large outfield. Since Canadian football fields are larger than American ones, the design specifications for Canadian facilities are somewhat less demanding. The particular design to accommodate both is usually an oval, although some later designs use an octorad. While building stadiums in this way means that sports teams and governments can share costs, it also presents some challenges.
