township, Burlington county, western New Jersey, U.S. It lies midway between Camden and Trenton (both in New Jersey) on Rancocas Creek, just upstream from the creek's mouth in the Delaware River. English Quakers settled there about 1677. The community, which originally included what is now Edgewater Park township, Delanco township, Rancocas village, and Beverly, was called Wellingborough (from Wellingborough, England), then Willingboro when it became a town in 1682. It was incorporated as a township in 1798. In 1959 the name was changed to Levittown for Levitt & Sons, Inc., a building firm that had participated in community development, but the name Willingboro was restored in 1963. The Little Red Schoolhouse (1866), now a historical museum, has a display of artifacts. Pop. (1990) 36,291; (2000) 33,008.
