New York State Route 110 (NY 110) is a major north–south state highway along the western border of Suffolk County, New York. It runs between the village of Amityville in the town of Babylon and Halesite in the town of Huntington. NY 110 comes close to the Nassau County line several times in the town of Babylon, which is only surpassed by NY 108 in distance to the county line for a state highway.
