Bull Run CDP (Fairfax County), VA

This Bull Run is the broad western Fairfax County census place, distinct from the much denser Bull Run community across the county line in Prince William. It was first delineated for the 2020 census and gathers subdivisions and open land around Virginia Run, Pleasant Valley Road, Compton Road, and the Centreville side of Bull Run. Most addresses say Centreville, and Virginia Run is often the more familiar neighborhood name. The settlement pattern is loose by Fairfax standards: curving subdivision streets and large detached homes give way quickly to woods, stream valleys, utility land, a quarry, and parcels that remain undeveloped or conservation-zoned.

The two runs give the place its name and much of its landscape. Bull Run follows the Fairfax–Prince William boundary, while Cub Run drains the developed Centreville area before entering a wider, forested floodplain. Stream-valley parks protect long green corridors through the neighborhoods, and the lower reaches of Cub Run retain strong habitat where they approach Bull Run. The largest shared landmark is the 1,500-acre Bull Run Regional Park. Its campground, picnic grounds, playgrounds, disc golf, seasonal waterpark, and festival grounds draw visitors from around Northern Virginia, while the trails lead into quieter woods. The park is also the northern trailhead of the 19.7-mile Bull Run–Occoquan Trail.

Daily life is suburban and car-dependent, without a single Bull Run town center. Pleasant Valley and Compton roads feed toward Route 29, Route 28, and Interstate 66, and most shopping and services are in Centreville or Chantilly. Sidewalks and paths are common inside newer subdivisions, then become patchier along older rural roads. A shared-use path on Compton Road helps link the neighborhoods with Bull Run Regional Park and the Cub Run trail network. Schools, pools, homeowners' associations, and youth sports provide much of the local social structure. The result feels like an outer edge of metropolitan Fairfax County: established residential communities sit close to major commuter routes, yet a surprisingly large amount of stream valley, parkland, and open ground still breaks up the development.
