New York State Route 210 (NY 210) is a state highway in Orange County, New York, in the United States. It runs north from the New Jersey state line—where it continues south as Passaic County Route 511 (CR 511)—along the west shore of Greenwood Lake to the eponymous village of Greenwood Lake, where it ends at a junction with NY 17A. It was once much longer, as it originally extended east along NY 17A and CR 106 in Orange and Rockland counties to Stony Point when it was assigned as part of the 1930 renumbering of state highways in New York. The route was truncated to its current length in 1982. Prior to becoming NY 210 in 1930, the road alongside Greenwood Lake was part of NY 55, a route connecting New Jersey to Goshen, in the 1920s.

NY 210 commences at the New York–New Jersey state line in the town of Warwick, where it connects to CR 511 in Passaic County, New Jersey. Like CR 511 in New Jersey, NY 210 is the primary lakeside roadway along Greenwood Lake, an interstate lake located roughly equally in New Jersey and New York. NY 210 heads north from the state line along the western edge of the base of a deep valley surrounding the lake to a community known as Indian Park, entirely situated on the steep incline leading away from the lake. The route continues on to the eponymous village of Greenwood Lake, located at the northern tip of the lake.
