Ball's Bluff National Cemetery is located on Route 7 two miles northeast of Leesburg, Virginia. It is surrounded by Ball's Bluff Regional Park owned and operated by the Northern Virginia Regional Park Authority. The cemetery contains remains of 54 Union soldiers killed during the Battle of Ball's Bluff 21 October 1861. The half acre site, surrounded by a low stone wall, contains 25 graves into which remains of 53 unknown soldiers and one known soldier (Grave 13: James Allen of Co. H, 15th Massachusetts Infantry) were buried. It is closed to new interments and is managed by the Culpeper National Cemetery. Ball's Bluff National Cemetery was designated a National Historic Landmark in 1984 by the National Park Service.

Land for the half-acre cemetery was acquired through donation in 1865, and the government received a quitclaim deed from the original owner's heirs in 1904. At the time of the Battle at Ball's Bluff in 1861, ownership of this land was in dispute. This dispute was not settled until 1870 when local courts awarded Margaret Jackson clear title. Margaret Jackson, for whom little information can be found, is listed in the 1850 Census with ten children and in the 1860 Census with seven children with the post office as Goresville. One year later in 1871, Jackson sold 41 acres to Thomas Swann (1809-1883), at various times mayor of Baltimore, governor of Maryland, US Representative and owner of the Morven Park estate in Leesburg, VA. In 1875 Swann sold the land reserving to the United States Government a small plot for the cemetery and land for an access road.
