Four Mile Fork is an unincorporated community in Spotsylvania County, Virginia, United States, south of the city limits of Fredericksburg.

[1] The community began developing as a suburb of Fredericksburg in the mid-20th century, with tract housing spreading out from the city along U.S. Route 1 Business (or Lafayette Boulevard).

The completion of a highway interchange with U.S. Route 1 just south of Four Mile Fork spurred new development, including lodging, restaurants, and service stations.

The completion in 1980 of a regional shopping mall, Spotsylvania Mall (now Spotsylvania Towne Center) on Virginia Route 3 west of Fredericksburg, shifted the focus of commercial development from the Route 1 corridor to the west of the city, resulting in some decline in business activity and the closure or relocation of several prominent businesses.

Since the 1990s, however, new development to the south along Routes 1 and 208 and the redevelopment of older commercial properties around Four Mile Fork has renewed business interest in the community.
