Bridgehampton is a hamlet and census-designated place in the South Fork of Suffolk County, New York, USA. The population was 1,756 at the 2010 census.Bridgehampton is in the town of Southampton, on Long Island. Shortly after the founding of Southampton in 1640, settlers began to move east to the area known by the Shinnecock Indians as Sagaponack and Mecox. At the head of Sagg Pond the hardy settlers established a community called Bullhead, later renamed Bridgehampton?after the bridge built across the pond. Sagg Bridge was built in 1686 by Ezekiel Sandford. The bridge was the link between Mecox and Sagaponack and gave this locality its name of Bridgehampton. The notorious criminal and memoirist Stephen Burroughs lived there during the 18th century and helped found the town's first library in 1793; the volumes he purchased could be found in the Bridgehampton Public Library as late as 2002.
