New York State Route 120 (NY 120) is a state highway in southern Westchester County, New York, in the United States. It begins in the city of Rye at an intersection with U.S. Route 1 (US 1) and runs for about 18 miles (29 km) north to the hamlet of Millwood, where it ends at a junction with NY 100. The route intersects with Interstate 684 (I-684) and the Saw Mill River Parkway, and serves the Westchester County Airport in North Castle. Portions of the route have been signed ceremonially in remembrance of American serviceman killed in the 2000s and 2010s during the wars in Iraq and Afghanistan.
NY 120 was assigned as part of the 1930 renumbering of state highways in New York, but only to the portion of its routing north of Westchester Avenue. It was extended south to Rye c. 1938, then rerouted to follow Westchester Avenue east to Port Chester by the following year. Most of NY 120's former routing to Rye became part of New York State Route 119A at that time. NY 120 was rerouted to serve Rye again in October 1960, replacing NY 119A.
