New York State Route 10 (NY 10) is a north–south state highway in the Central New York and North Country regions of New York in the United States. It extends for 155 miles (249 km) from the Quickway (NY 17) (Future Interstate 86) in Deposit, Delaware County to NY 8 at Higgins Bay, a hamlet in the Hamilton County town of Arietta. NY 10 begins concurrent with NY 8. While NY 8 follows a more westerly alignment between Deposit and Higgins Bay via Utica, NY 10 veers to the east, serving Delhi, Cobleskill, and Canajoharie. Along the way, the road intersects Interstate 88 (I-88) near Cobleskill and U.S. Route 20 (US 20) in Sharon Springs.
NY 10 was assigned in 1924; however, it initially followed a completely different alignment than it does today. At the time, it began at the New Jersey state line in Rockland County and followed modern US 9W north to Albany. From here, it continued to Saranac Lake via Schenectady, Saratoga Springs, Lake George, Chestertown, North Creek, Long Lake, and Tupper Lake. It was extended northeast to Plattsburgh by 1926 but truncated to Schenectady in 1927. In the 1930 renumbering of state highways in New York, all of NY 10 south of Long Lake and north of Lake Clear Junction was moved onto a new, more westerly alignment through the state. The route was cut back to its current northern terminus in Arietta c. 1960.
