New York State Route 42 (NY 42) is a north–south, discontinuous state highway in the Catskill Mountains region of New York in the United States. The southernmost of the highway's two segments begins at an intersection with U.S. Route 6 (US 6) and US 209 in Port Jervis and ends at a junction with NY 55 near the Rondout Reservoir in Neversink. NY 42's northern segment runs from NY 28 in Shandaken to NY 23A in Lexington. The 41-mile (66 km) southern segment is located in Orange County and Sullivan County, while the 11-mile (18 km) northern segment is in Ulster County and Greene County.

NY 42 is one of three state routes in New York that is split into two segments; the others are NY 24 and NY 878, both located on Long Island. Like NY 24, NY 42 was a continuous route when it was assigned as part of the 1930 renumbering of state highways in New York. The portion of the route between Neversink and Shandaken was eliminated in the mid-1930s.
