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. The CDP population was 200 at the 2010 census.
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. It lies between Napeague State Park on the west and Hither Hills State Park on the east.
