Brookhaven, New York, can refer to both the historic Brookhaven hamlet on Long Island’s South Shore and the much larger Town of Brookhaven, which covers an extensive portion of central Suffolk County. The hamlet is a small residential and waterfront community near Bellport Bay, the Carmans River, and protected coastal wetlands. It is known for its quiet streets, historic homes, natural surroundings, and proximity to Bellport, Wertheim National Wildlife Refuge, and the Great South Bay.

It includes major communities such as Stony Brook, Setauket, Port Jefferson, Patchogue, Bellport, Medford, Coram, Mastic, Shirley, and dozens of other hamlets and villages. Together, these communities make Brookhaven one of Long Island’s most geographically varied and economically important towns.
