"United States national cemetery" is a designation for 147 nationally important cemeteries in the United States. A national cemetery is generally a military cemetery containing the graves of U.S. military personnel, veterans and their spouses, but not exclusively so. There are also state veteran cemeteries.
The best known national cemetery is Arlington National Cemetery in Arlington County, Virginia, outside Washington, D.C.
Some national cemeteries, especially Arlington, contain the graves of important civilian leaders and other important national figures. Some national cemeteries also contain sections for Confederate soldiers.
The National Cemetery Administration of the United States Department of Veterans Affairs maintains 131 of the 147 national cemeteries as well as the Nationwide Gravesite Locator, which can be used to find burial locations of American military veterans. The Department of the Army maintains two national cemeteries, Arlington National Cemetery and United States Soldiers' and Airmen's Home National Cemetery. The National Park Service (NPS) maintains 14 cemeteries associated with historic sites and battlefields.
The American Battle Monuments Commission, an independent agency, maintains 24 American military cemeteries and other memorials outside of the United States.
The first national cemeteries were set up after the United States Civil War by Edmund Burke Whitman. Congress passed a law to establish and protect national cemeteries in 1867.
