unincorporated village in Brookhaven town (township), Suffolk county, southeastern New York, U.S. Located on the northern shore of Long Island, on Stony Brook Harbor, it was settled by Boston colonists in 1655. In the 19th century the shipbuilding industry flourished there. Stony Brook is now a tourist and educational centre for the area and is an example of a rehabilitated community, whose downtown was largely rebuilt in the Federal architectural style in the early 1940s. It has art and history museums, and its Carriage House museum houses an international collection of more than 250 horse-drawn vehicles. A grist mill, built there in 1699 (rebuilt c. 1751), operated commercially until 1952; subsequently restored, it continues to function as a working museum. The Stony Brook campus (1956) of the State University of New York (New York, State University of (SUNY)) system was moved there in 1962 from Oyster Bay. Pop. (1990) 13,726; (2000) 13,727.
