Lloyd Harbor is a village in the Town of Huntington in Suffolk County, on the North Shore of Long Island, in New York, United States.

[2] In 1654, the Matinecock Native Americans sold 3,000 acres (12 km2) of what is now called Lloyd Neck to English settlers from Oyster Bay.

Henry Lloyd farmed the land and erected a house, which still survives in Caumsett State Park.

[3][4][5][6][7][8] The 1900s ushered the era of the Long Island Gold Coast, and various wealthy families began to buy land and build seaside mansions and estates.

These included William Matheson, Marshall Field III, Ronald Conklin, Harold Dimppel, Sr., Ferdinand Eberstadt and George McKesson.

Robin Gibb, Charles Lindbergh, Jerry Seinfeld and Billy Joel have each lived on the Neck for a time.

In 1969 the Long Island Lighting Company proposed locating a nuclear power plant in the community.

Local opposition quickly defeated the plan, with Ferdinand Eberstadt donating his 80-acre (320,000 m2) estate to the U.S.
