Southeast DC is the southeastern quadrant of the city, located south of East Capitol Street and east of South Capital Street. It has a rich cultural history, including the historic Anacostia neighborhood, the Navy Yard, the Anacostia River waterfront, the remains of several Civil War-era forts, RFK Stadium and the Congressional Cemetery. It also is plagued by a reputation of having a relatively high crime rate. The population of Southeast is almost entirely African-American.

Politically, Southeast includes most of Ward 8, as well as much of Wards 6 and 7 and part of Ward 2. Ward 8 is home to former mayor Marion Barry.

It is accessible via the Blue, Orange and Green Lines of the Washington Metro.
