The Defense Intelligence Agency Headquarters (DIA HQ) is the main operating center of the Defense Intelligence Agency. It is located on the premises of Joint Base Anacostia–Bolling in Washington, DC.

The Anacostia River is a river in the Mid Atlantic region of the United States. It flows from Prince George's County in Maryland into Washington, D.C., where it joins with the Washington Channel to empty into the Potomac River at Buzzard Point. It is approximately 8.7 miles (14.0 km) long. The name "Anacostia" derives from the area's early history as Nacotchtank, a settlement of Necostan or Anacostan Native Americans on the banks of the Anacostia River. Heavy pollution in the Anacostia and weak investment and development along its banks have led to it becoming what many have called "D.C.'s forgotten river." In recent years, however, private organizations, local businesses, and the D.C., Maryland and federal governments have made joint efforts to reduce its pollution levels in order to protect the ecologically valuable Anacostia watershed.

Joint Base Anacostia–Bolling is a 905-acre (366 ha) military installation, located in Southeast, Washington, D.C., established on 1 October 2010 in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of Naval Support Facility Anacostia (NSF) and Bolling Air Force Base (BAFB), which were adjoining, but separate military installations, into a single joint base, one of twelve formed in the country as a result of the law. The base hosts the Defense Intelligence Agency Headquarters amongst its other responsibilities. The only aeronautical facility at the base is a 100-by-100-foot (30 by 30 m) helipad (ICAO: KBOF).

Bolling Air Force Base or Bolling AFB was a United States Air Force base in Washington, D.C. In 2010, it was merged with Naval Support Facility Anacostia to form Joint Base Anacostia–Bolling. From its beginning, the installation has hosted elements of the Army Air Corps (predecessor to today's Air Force) and Navy aviation and support elements.
