New York State Route 30 (NY 30) is a state highway in the central part of New York in the United States. It extends for 300.71 miles (483.95 km) from an interchange with NY 17 in the Southern Tier to the Canada–US border in the state's North Country, where it continues into Quebec as Route 138. On a regional level, the route serves to connect the Catskill Park to the Adirondack Park. In the latter, NY 30 is known as the Adirondack Trail. Aside from the state parks, the route serves the city of Amsterdam (where it meets the New York State Thruway) and several villages.

NY 30 was assigned in the 1930 renumbering of state highways in New York to most of its modern routing south of Wells, replacing a series of designations that had been assigned to the highway in the 1920s. The portion of what is now NY 30 north of Speculator was initially part of NY 10. When that route was truncated to Arietta c. 1960, NY 30 was extended northward over NY 10's former alignment by way of an overlap with NY 8.
