Napeague (/ˈnæpiːɡ/, NAP-eeg) is a census-designated place (CDP) that roughly corresponds to the hamlet with the same name in the Town of East Hampton in Suffolk County, New York, United States.

[2] Napeague is located on a very narrow, low-lying strip between the Atlantic Ocean to the south and Gardiners Bay to the north that was flooded in the Great Hurricane of 1938.

[3] The hamlet's three major landmarks are the Mackay Radio Tower, the Art Barge, and the Smith Meal Fish Factory.

At the height of World War II the tower was used for responding to upwards of ten SOS calls a day from ships at sea.

on January 28, 1961, an American Airlines Boeing 707 Flight 1502 (Flagship Oklahoma) with an engine on fire nosedived over the towers before crashing about 300 yards (270 m) off the Napeague coast, killing all six aboard.

D'Amico, looking for a permanent home, worked with local baymen to beach a retired World War II barge at its current location just northeast of the Mackay Towers.

A complement to The Art Barge is the Mabel and Victor D'Amico Studio and Archive, the former home of Victor and his wife, the artist teacher Mabel Birckhead D'Amico, found across Napeague Harbor on the Lazy Point peninsula.

[9] Next to the Smith meal plant is a private marine finfish hatchery, Multi Aquaculture Systems, founded in 1976 by Dr. Robert J. Valenti, and a small restaurant.

[10] The closed Smith Meal Fish Factory was sold to The Nature Conservancy, who transferred it to the State Parks Commission.

[11] The park has been undeveloped since its transfer in 1986 and is home to a nesting colony of piping plover which will dictate its future use.

In the intervening several thousand years, ocean currents, or littoral drift, filled in this space with sand, giving rise to Napeague.

It acquired this nickname, according to local lore, because of the menhaden plant located there in years gone by, which "stunk to high heaven".
