Westampton Township was organized from the township of Northampton by an Act of Assembly dated March 6, 1850. It received its name as the "western" portion of Northampton. In 1854 a part was added from Pemberton Township and in 1880 Eastampton Township was formed from Westampton. In 1956 the township was completed with Willingboro Township giving the balance of Rancocas Village to Westampton Township.

The area of the township today is 12 square miles with the Rancocas Creek forming a natural southern border. The township is bounded on the west by Willingboro, on the north by Burlington Township and Springfield, and on the east by Eastampton and Mt. Holly. An early description of the area reports a slightly rolling surface with soil that is good, though light and sandy and in some places underlaid with good brick clay. Several brickyards turned out thousands of bricks and drainage tiles in the 1700's.

Westampton is rich in history. The first inhabitants were the Lenni-Lenape or Delaware Indians. The first Quaker settlers arrived in Burlington County in 1677 and some settled on the meadow bank of the Rancocas Creek. Rancocas Village, 101 homes in a State and National Historic District, developed around the Rancocas Friends Meeting House which was erected in 1772. The Village was divided between Westampton and Willingboro until 1956. The Rancocas Post Office was established in 1838 and is still in operation.

The township government consists of a five member elected committee, fully staffed municipal offices, a 22 member Police Department, and a combined paid and volunteer fire company and emergency squad. Numerous boards and commissions are made up of concerned citizens from all walks of life. An active recreation program provides a myriad of activities for our residents. Our residents can enjoy numerous tennis courts, a roller hockey court, four playgrounds and two baseball/softball fields
