New York State Route 9N (NY 9N) is a north–south state highway in northeastern New York in the United States. It extends from an intersection with U.S. Route 9 (US 9), NY 29, and NY 50 in the city of Saratoga Springs to a junction with US 9 and NY 22 in the Clinton County hamlet of Keeseville. At 143.49 miles (230.92 km) in total length, NY 9N is the longest letter-suffixed route in the state. It is concurrent with its parent route for 1 mile (1.6 km) in the village of Lake George and for three blocks in the hamlet of Elizabethtown.

Much of NY 9N runs alongside either a river or a lake. It follows the Hudson River through northern Saratoga County and southern Warren County, the entirety of Lake George's western shoreline, the west edge of Lake Champlain between Ticonderoga and Westport, and the Ausable River from Keene to Keeseville. The other portions of NY 9N pass through predominantly rural and mountainous regions of the Adirondack Mountains.
