Chantilly is a census-designated place (CDP) in western Fairfax County, Virginia. The population was 24,301 as of the 2020 census. Chantilly is named after an early-19th-century mansion and farm, which in turn took the name of an 18th-century plantation that was located in Westmoreland County, Virginia. The name "Chantilly" originated in France with the Château de Chantilly, about 28 miles north of Paris.

The Stone House. The only building of the former Chantilly Plantation (not to be confused with the Sully Plantation) that still exists today. It is located on the north side of Route 50, across from the Greenbriar Shopping Center. Historical evidence strongly suggests the Stone House was an overseer's quarters before the Civil War, and became a tavern later.
