West Hampton Dunes is an incorporated village in the Town of Southampton on Westhampton Island, in Suffolk County, New York, United States.

Specifically, the village wanted to have a say in U.S. Army Corps of Engineers handling of the barrier beach—particularly in response to a series of groynes at Shinnecock Inlet that have created major beach erosion "downstream" in the longshore drift.

Almost immediately after incorporation, Gary Vegliante, the village's first and to date only mayor, sued the U.S. Army Corps of Engineers for $200 million.

In 1996, the village, under the authority of a court order, formed a law enforcement agency to better serve the needs of the community.

The West Hampton Dunes Police Constabulary consists of approximately 12 members, including a department commissioner and two sergeants.

The members of the department also receive the required DCJS courses for peace officers to perform traffic enforcement duties including Radar/LIDAR, Standard Field Sobriety, and Basic Crash Management.
