New York State Route 11B (NY 11B) is a state highway in northern New York in the United States. It provides a parallel, more southerly east–west route to U.S. Route 11 between US 11 in Potsdam and US 11, NY 30, and NY 37 in Malone. NY 11B serves both the Potsdam Municipal Airport and the riverside hamlet of Nicholville, where NY 11B meets NY 458. Aside from the two villages at each end of the route and the hamlet of Nicholville near the midpoint, NY 11B passes through rural, lightly populated areas, as does its parent to the north. In Malone, NY 11B overlaps NY 30 for one block in order to reconnect to US 11.
NY 11B was assigned as part of the 1930 renumbering of state highways in New York, but to a completely different routing than it follows today. Initially, it was a connector between then-NY 72 in Nicholville and US 11 in Lawrenceville. The route was extended west to Potsdam by 1931 and rerouted to run from Nicholville to Malone c. 1938. The latter realignment supplanted New York State Route 187, an east–west highway assigned in 1930 that initially extended from Nicholville to North Bangor but was later realigned to serve Malone.
