Northville is a charming hamlet and census-designated place located on the North Fork of Long Island, within the Town of Riverhead in Suffolk County, New York. Situated along the Long Island Sound, it offers a more rural and less densely populated environment compared to many other parts of Long Island. Notably, Northville was an incorporated village for a brief period between 1921 and 1930. Today, it retains a quieter, coastal atmosphere with a connection to the area's agricultural and maritime history.
