Haddonfield is a borough located in Camden County, New Jersey, United States. As of the 2010 United States Census, the borough had a total population of 11,593, reflecting a decline of 66 (-0.6%) from the 11,659 counted in the 2000 Census, which had in turn increased by 31 (+0.3%) from the 11,628 counted in the 1990 Census.
Haddonfield was incorporated by an act of the New Jersey Legislature on April 6, 1875, within portions of Haddon Township following a referendum on the same day. The borough became an independent municipality in 1894. The borough was named for Elizabeth Haddon, an early settler of the area.
The Haddonfield area was occupied by Lenni Lenape Native Americans. The Lenape disappeared from the local area when settlers arrived. Arrowheads and pottery shards have been found by residents by the banks of the Cooper River, hinting that there was a Native American settlement in Haddonfield at one point in time.
On October 23, 1682, Francis Collins, an English Quaker and a bricklayer by trade, became the first settler within the boundaries of what today is Haddonfield. Collins soon built a house, "Mountwell," on a tract of 400 acres. Haddonfield was further developed by Elizabeth Haddon (1680–1762), whose Quaker father, John Haddon, bought a 500 acres (2.0 km2) tract of land in the English colony of West Jersey to escape religious persecution. Elizabeth set sail alone from Southwark, England to the New World in 1701.
