Chantilly is acensus-designated place (CDP) in westernFairfax County, Virginia, United States.[4][5] The population was 24,301 as of the 2020 census.[1]Located in theNorthern Virginia portion of theWashington metropolitan area, Chantilly sits approximately 25 miles (40 km) west ofWashington, D.C., viaInterstate 66 andU.S. Route 50. It is located betweenCentreville to the south,Herndon andReston to the north and northeast, respectively, andFairfax 7 miles (11 km) to the southeast. U.S. Route 50 andVirginia State Route 28 intersect in Chantilly, and these highways provide access to theDulles/Reston/Tysons Corner technology corridor and other major employment centers in Northern Virginia and Washington, D.C.

The name Chantilly originates from the Chantilly Plantation, established in the early19th century by Charles Calvert Stuart and his wife, Cornelia Lee Turberville Stuart. Cornelia inherited part of the Leeton estate from her father, George Richard Lee Turberville, and the couple built their mansion around 1817, naming it after the Westmoreland County estate previously owned by her grandfather,Richard Henry Lee, a signer ofthe Declaration of Independence.[6]
The name “Chantilly” itself came fromChâteau de Chantilly inFrance. Richard Henry Lee had named his estate “Chantilly” in 1763, which is believed to be the origin of the name later used by the Stuarts. The mansion was constructed using localred sandstone quarried from the property. Over time, the name "Chantilly" came to refer not only to theplantation but also to the surrounding area as the region developed.[7]
The broader Chantilly area often includes neighboringSouth Riding. The official Chantilly CDP is withinFairfax County, while theSouth Riding CDP is in neighboringLoudoun County, both sharing the "Chantilly" mail address andZIP codes 20151/20152. Residents of both areas are situated alongU.S. Route 50 andVirginia State Route 28.[8]

Chantilly was home to a number of colonial plantations in the 1700s, including the Sully Plantation (now theSully Historic Site) built byRichard Bland Lee I. Other plantations included George Richard Lee Turberville's "Leeton Grove"[9] (originally a 5,000+ acre plantation, the main house of which still stands at 4619 Walney Rd.), the John Hutchison Farm, and the Chantilly Plantation. During theCivil War,federal troops destroyed by fire the Chantilly Plantation manor house. One building remains, a stone house across Route 50 from the Greenbriar Shopping Center. While it is not clear what this stone house was used for, most historical evidence suggests it was probably a plantation overseer's quarters during the antebellum period, and a tavern or boarding house following the war. After the war, Cornelia Stuart, who had become deeply in debt, sold her 1,064-acre (431 ha) Chantilly estate. The advertisement for the sale referenced several "tenements", one of which was the Stone House.
The village grew during the 19th century, particularly following the construction of theLittle River Turnpike toWinchester.
The evolution of the Chantilly area into an outer suburb of Washington, D.C., gained momentum after 1980, as developers built residential subdivisions and commercial areas, filling in the farmland south of Dulles Airport.

During theAmerican Civil War on September 1, 1862, theBattle of Chantilly (or Ox Hill) was fought nearby. Following his victory at theSecond Battle of Bull Run (or Second Manassas),Confederate GeneralRobert E. Lee directed Major GeneralThomas J. "Stonewall" Jackson to crossBull Run on August 31 and sweep around the position of Major GeneralJohn Pope's Union Army of Virginia atCentreville. Reaching the Little River Turnpike (now U.S. Route 50) northwest of Centreville, Jackson turned southeastward toward Fairfax Court House (now the city ofFairfax) to strike in rear of Pope's army.
During September 1, Pope, apprised of Jackson's movement, began to withdraw toward Fairfax Court House. Late in the day, Jackson clashed with Union forces under Brigadier GeneralIsaac Stevens and Major GeneralPhilip Kearny near Ox Hill, west of Fairfax. During the ensuing battle, which was fought amid a raging storm, both Union generals Stevens and Kearny were killed. The fighting ended at dusk, and Pope's army continued its withdrawal to Fairfax and subsequently to the Washington defenses.
Although commercial and residential development now covers most of the Chantilly (Ox Hill) battlefield, the smallOx Hill Battlefield Park preserves a 5-acre (20,000 m2) portion of the battle site.
