Woodbridge is a census-designated place (CDP) in Prince William County, Virginia, United States, located 20 miles (32 km) south of Washington, D.C. Bounded by the Occoquan and Potomac rivers, Woodbridge Magisterial District had 54,275 residents at the 2010 census.
Woodbridge was a village composed largely of either farms or industrial complexes. Later, the Woodbridge postal delivery area became the hub that included Dale City and Lake Ridge, which had previously been forged as a planned community in the 1960s and 1970s. The area takes its name from Thomas Mason's 1795 wooden toll bridge built to supplant the existing ferry, carrying the King's Highway traffic across the Occoquan River. Mason's Woodbridge Plantation was located in the area of the present day Belmont Bay golf course community. The Freestone Point Confederate Battery and Rippon Lodge are listed on the National Register of Historic Places.
