New York State Route 23 (NY 23) is an east–west state highway in the eastern portion of New York in the United States. It extends for 156.15 miles (251.30 km) from an intersection with NY 26 in the Central New York town of Cincinnatus in Cortland County to the Massachusetts state line in the Berkshire Mountains, where it continues east as that state's Route 23. Along the way, it passes through many communities, including the cities of Norwich and Oneonta. Outside of the communities, the route serves largely rural areas of the state and traverses the Catskill Mountains in the state's Central New York Region. NY 23 crosses the Hudson River at Catskill via the Rip Van Winkle Bridge.

Sections of what is now NY 23 were part of unsigned legislative routes as early as 1908; however, NY 23 itself was not assigned until 1924. At the time, the route extended from Oneonta to Massachusetts and followed a slightly different alignment from Cairo to Claverack via Hudson that took the route along modern County Route 23B (CR 23B) in eastern Greene County. NY 23 was extended west to Norwich in the mid-1920s and to NY 26 in northwestern Chenango County in 1930. The route was gradually moved onto its current alignment between Cairo and Claverack in the 1950s and 1960s, and realigned on its western end in 1984 to serve Cortland County.
