World War I Medal of Honor recipients buried at Arlington National Cemetery

Arlington National Cemetery is a United States military cemetery located in Arlington County, Virginia near The Pentagon and directly across the Potomac River from the Lincoln Memorial. The cemetery has graves for thousands of casualties and deceased veterans of the nation's conflicts, beginning with the American Civil War but includes reinterred dead from earlier wars as well. It was established during the Civil War on the grounds of Arlington House, which had been the estate of the family of Confederate general Robert E. Lee's wife Mary Anna (Custis) Lee (a great-granddaughter of Martha Washington).

The Medal of Honor was created during the American Civil War and is the highest military decoration presented by the United States government to a member of its armed forces. The recipient must have distinguished themselves at the risk of their own life above and beyond the call of duty in action against an enemy of the United States. Due to the nature of this medal, it is commonly presented posthumously.
