New York State Route 427 (NY 427) is an east–west state highway in Chemung County, New York. It extends for 11.5 miles (18.5 km) from its western terminus at an intersection with NY 14 in the town of Southport, south of the city of Elmira, to its eastern terminus at an interchange with I-86/NY 17 in the town of Chemung. Between those two towns, the highway passes through the town of Ashland and serves the village of Wellsburg. Much of NY 427 follows the Chemung River.

The route number 427 was assigned in the early 1940s, and replaced the ennumeration New York State Route 17D. Route 17D was established as part of the 1930 renumbering of state highways in New York. It originally began in downtown Elmira and ended at the Pennsylvania state line in Chemung. NY 427 was realigned on its east end in 1967 to meet the newly constructed exit 59 on NY 17 and on its west end in 1978 to follow what had been New York State Route 379 through the town of Southport. Other minor realignments occurred during the route's history.
