The Montaukett, ("Metoac") or Montauk people are an Algonquian-speaking Native American culture from the eastern end of Long Island, New York.

Historically, they are related in language and ethnicity to the Pequot and Narragansett peoples who live across Long Island Sound in what is now Connecticut and Rhode Island, and they are initially speakers of the "N" dialect of Algonquin language until about 1600 when they move to the "Y" dialect.

Relics and ruins of their settlements are visible at Theodore Roosevelt County Park, on the edge of the village of Montauk, New York.

While descendants of this tribe still live among the neighboring tribes in the region, the Montaukett are not a New York State recognized tribe yet (though efforts towards recognition are being made).
