New York State Route 118 (NY 118) is a north–south state highway that extends for 10.71 miles (17.24 km) in Downstate New York in the United States. Much of the highway is located within Westchester County; however, a small portion of the route near the northern terminus is situated in Putnam County. The southern terminus of the route is at an intersection with NY 100 in the town of Yorktown. Its northern terminus is at a junction with U.S. Route 6 (US 6) in the town of Carmel. NY 118 passes through the hamlets of Yorktown Heights and Amawalk, where it overlaps with US 202 and NY 35. The route was assigned as part of the 1930 renumbering of state highways in New York; however, it was initially routed on the portion of modern NY 100 and US 202 between the New Croton Reservoir and Croton Fal
