Ball's Bluff Battlefield Regional Park and National Cemetery is a battlefield area and a United States National Cemetery, located 2 miles (3.2 km) northeast of Leesburg, Virginia. The cemetery is the third smallest national cemetery in the United States. Fifty-four Union Army dead from the Battle of Ball's Bluff are interred in 25 graves in the half-acre plot; the identity of all of the interred except for one, James Allen of the 15th Massachusetts, are unknown. Monuments to fallen Confederate Sergeant Clinton Hatcher and Union brigade commander Edward Dickinson Baker are located next to the cemetery, though neither is buried there. While the stone wall-enclosed cemetery itself is managed through the Culpeper National Cemetery and owned by the Department of Veterans Affairs, the balance of the 223-acre (0.90 km2) park is managed through the Northern Virginia Regional Park Authority.

The United States National Cemetery System is a system of 164 cemeteries in the United States and its territories. The authority to create military burial places came during the American Civil War, in an act passed by the U.S. Congress on July 17, 1862. By the end of 1862, 12 national cemeteries had been established. Two of the nation's most iconic military cemeteries, Arlington National Cemetery and Gettysburg National Cemetery were established in 1864 and 1863, respectively.
