New York State Route 37 (NY 37) is a state highway in the North Country of New York in the United States, extending for 127.40 miles (205.03 km) on a west–east axis. The western terminus of the route is at an intersection with U.S. Route 11 (US 11) in Pamelia, Jefferson County. Its eastern terminus is at a junction with US 11, NY 11B, and NY 30 in Malone, Franklin County. In between the termini, NY 37 passes through Ogdensburg and Massena. It is a two-lane, nondivided, full access roadway for most of its entire length, except for portions between Massena and western Franklin County, where the route widens to a four-lane divided highway.

NY 37 was assigned in 1930 to the portion of the Theodore Roosevelt International Highway between Redwood and Malone as well as to a previously unnumbered roadway between Watertown and Redwood. The Redwood–Malone portion was originally part of NY 3 when the first set of posted routes in New York were assigned in 1924. NY 37 has since been rerouted in areas, primarily near Ogdensburg and Massena.
