Wexford is an unincorporated community in Allegheny County, Pennsylvania, United States. The area known as Wexford is split among multiple municipalities, including Franklin Park, McCandless Township, Pine Township, and Marshall Township. It is named after County Wexford in Ireland. Unlike most of Allegheny County, Wexford was removed from area code 412 when it was subdivided in 1998, being placed in area code 724 instead. Part of this was because of Wexford's close proximity to Cranberry Township, one of the fastest-growing areas in the United States.
