Wincoma is a hamlet in on the westernmost headland of East Neck in the Town of Huntington, in Suffolk County, on the North Shore of Long Island, in New York, United States.
The hamlet survives within the Village of Huntington Bay in the Town of Huntington.[1] Wincoma was an estate-heavy enclave and many maps denote it to this day because of its importance in literature and media of the Gilded Age.[citation needed] It is now mainly smaller homes rather than estates. Access to Wincoma Beach is restricted and available only to residents and their guests.[citation needed]
