Dale City is a census-designated place (CDP) in Prince William County, Virginia, United States, located 25 miles (40 km) south west of Washington, D.C.

Hylton began his career as a "huckster", a young man who sold farm goods and produce at the farmers' market in Washington, DC.

[6] His company, Hylton Enterprises, began Dale City in 1960 approximately 1 mile east of Interstate 95 and continued to build west towards Hoadly Road (State Route 642).

More recently, the Hylton Foundation underwrote a major new addition to Potomac Hospital in nearby Woodbridge.

Because Dale City was built before most of eastern Prince William County was developed, it has its own water and sewer systems, separate from the ones in Occoquan, Woodbridge, Dumfries, Triangle, and Lake Ridge.

[7][8] Russell House and Store is a historic early 19th century building, located on Minnieville Road.

The streets along Dale Boulevard (generally) proceed alphabetically when followed from east to west starting from Gideon Dr. and ending at Hoadly Rd.

: Ashdale, Barksdale, Birchdale, Cherrydale, Cloverdale, Darbydale, Emberdale, Evansdale, Forestdale, Glendale, Hillendale, Kerrydale, Kirkdale, Lindendale (which includes Surrydale Ct.), Mapledale, Nottingdale, Orangedale, Princedale, Queensdale, Ridgedale, Silverdale, and Trentdale.

[10] According to the United States Census Bureau, the CDP has a total area of 15.0 square miles (39.0 km2), all of it land.

The Consulate-General of El Salvador in Woodbridge is located at 14572 Potomac Mills Road in the Dale City CDP.
