Clear Brook is an unincorporated farming community in northern Frederick County, Virginia.

The community lies approximately six miles (9.6 kilometers) north of the county seat of Winchester along Martinsburg Pike (U.S. Route 11).

It is the site of the Kenilworth home, once owned by Harry K. Thaw, the old Hopewell Meeting House, Stonewall Elementary School, the Clearbrook Park, and the Frederick County Fairgrounds.

Clear Brook drew national attention when resident and Quaker peace activist Tom Fox was kidnapped in Baghdad on November 25, 2005.

Clear Brook was selected as the site for the Hogging Up BBQ & Music Festival,[2] a Kansas City Barbeque Society sanctioned event deemed a "State Championship" by the Governor of Virginia for 2013.
