Dunehampton is the name of a formerly proposed village in the Town of Southampton, in Suffolk County, on the South Fork of Long Island, in New York, United States.

It was proposed in 2003 to be incorporated along 5 miles (8.0 km) of Atlantic Ocean beach between Village of Southampton and the hamlet of Wainscott.

In the early 2000s, residents proposed incorporating the community as a village to maintain home rule – and out of dissatisfaction with the Town of Southampton's laws, including those pertaining to erosion and property regulations.

Healy ultimately ruled that Dunehampton's application was not valid because it lacked the necessary number of signatures.

[7][8][9] The proposal also met stiff resistance from the nearby communities of Water Mill, Bridgehampton, and Sagaponack because they feared the village would impose strict parking rules on the beaches cutting them off from the ocean.
