Ox Hill Battlefield Park is a site in Fairfax, Virginia, where the Battle of Ox Hill (Union name Battle of Chantilly) was fought during the American Civil War. It was the only major battle of the war fought in Fairfax County. The battlefield is now a public park adjacent to suburban developments and the Fairfax Towne Center shopping center, and is maintained by the Fairfax County Park Authority. The most prominent feature is a pair of monuments to the two Union generals killed during the battle, Isaac Stevens and Philip Kearny. Stevens was fatally shot within the area of the present-day park while Kearny was killed just to the west. There are also two Virginia historical markers placed near the park entrance commemorating the battle and aftermath. The park is located at 4134 West Ox Road, in Fair Lakes near Route 50, on the corner of West Ox Road (State Route 608) and Monument Drive (which was presumably named for the Kearny and Stevens memorial).

Union General John Pope learned of this action, and sent about 6,000 men to intercept. The two sides came into contact during the afternoon of September 1, 1862. The Confederate forces were on Ox Hill, alongside the Little River Turnpike, and the Union forces came from the south. A severe thunderstorm raged as each side attacked and counterattacked, and Union generals Stevens and Kearny were killed during the fighting. During a charge by the 79th New York Highlanders, later called the Cameron Highlanders, against Confederates massed in the woods, Stevens picked up the regiment's fallen colors and shouted, "Highlanders, my Highlanders, follow your general!" Within seconds, a Confederate bullet struck his head and he died instantly. After receiving a
