Elizabeth Haddon (1680-1762) was the founder of Haddonfield, New Jersey.

Elizabeth's Quaker father, John Haddon , bought a 500 acre (2 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. Shortly after her arrival, she made a marriage proposal to John Estaugh , a Quaker minister, and they were married in 1702.
