Stony Brook is a hamlet and census-designated place in the Town of Brookhaven in Suffolk County, New York, on the North Shore of Long Island. Begun in the colonial era as an agricultural enclave, the hamlet experienced growth first as a resort town and then to its current state as one of Long Island's major tourist towns and centers of education. Despite being referred to as a village by residents and tourists alike, Stony Brook has never been legally incorporated by the state. The population was 13,740 at the 2010 census.The CDP is adjacent to the main campus of Stony Brook University, a major research center within the State University of New York, and also the Stony Brook School, a private college preparatory school. It is also home to the Long Island Museum of American Art, History, and Carriages and the Stony Brook Village Center, a privately maintained commercial center that was planned in the style of a traditional New England village.
