West Falls Church is a census-designated place (CDP) in Fairfax County, Virginia, United States.

[3] The bulk of it is made of subdivisions built in the 1940s and early 1950s, including Jefferson Village, Westlawn, Hillwood, Sleepy Hollow, Woodley, Raymondale and Broyhill Park.

Following the American Civil War, local blacks established prosperous communities in an area then called South Falls Church, along Tinner's Hill and elsewhere.

It is speculated that the reason for the shrinking of the town limits was a fear of black power to swing local elections.

[4] This was never reversed, and caused the boundary of the future City of Falls Church to follow South Washington Street.

[1] When compared to other states, Virginia has a relatively high number of residents that were born in Bolivia, and West Falls Church has a population of 3,226 Bolivian Americans, which means West Falls Church is the 5th largest community of Bolivians in the United States.

General Dynamics, HITT Contracting, and Northrop Grumman have their corporate headquarters in West Falls Church.
