Fort Belvoir Community Hospital is a Department of Defense medical facility located on Fort Belvoir, Virginia, outside of Washington D.C. In conjunction with Walter Reed National Military Medical Center, Belvoir provides the Military Health System medical capabilities of the National Capital Region Medical Directorate (NCR MD), a joint unit providing comprehensive care to members of the United States Armed Forces located in the capital area, and their families. The facility is located on a U.S. Army installation, but operates as one of the first joint service medical facilities in the U.S. military, staffed with uniformed medical personnel from the Army, Navy, and Air Force. The hospital is one of the largest medical facilities in Northern Virginia, and provides all levels of inpatient and outpatient medical care. The facility maintains a 24 hour emergency department but, like most U.S. military hospitals, transfers patients in need of a trauma center to equipped civilian medical facilities. As part of federal emergency planning in the National Capitol Region, the hospital is also tasked with maintaining unique capabilities to support continuity of government operations in the event of crisis.The $1.03 billion, 1.3 million-square-foot facility opened in August 2011, replacing Fort Belvoir's existing medical facility, DeWitt Army Community Hospital, and integrating significant portions of the former Walter Reed Army Medical Center in Washington, D.C., in accordance with 2005 Base Realignment and Closure Act. In addition to its primary facility at Fort Belvoir, the hospital also operates the DiLorenzo TRICARE Health Clinic (DTHC) at the Pentagon and satellite health centers in Fairfax and Dumfries, Virginia.

The northern half was added between 1866 and 1869. Both halves are wood frame, one story, gable roofed structures. The style reflects the Quaker belief in simplicity and lack of adornment. The rectangular building faces east, with two entrances on the long side of the rectangle. One entrance was for women, and one for men. On the interior, there is a center wall with window-like opening. The openings can be shuttered to accommodate separate meetings for men and women. The seating is historic, simple, wooden benches.
