New York State Route 364 (NY 364) is a state highway located in the Finger Lakes region of New York in the United States. It extends for 24.59 miles (39.57 km) from an intersection with NY 14A in Penn Yan to a junction with the concurrent routes of U.S. Route 20 (US 20) and NY 5 just east of the Canandaigua city limits. NY 364 follows a predominantly east–west alignment from Penn Yan to Middlesex and a north–south routing from Middlesex to Canandaigua, resulting in an L-shaped alignment. As a result, the route is posted as north–south north of Middlesex and east–west east of the hamlet. In the Canandaigua area, the road serves as a connector between US 20 and NY 5, Finger Lakes Community College, and the eastern shore of Canandaigua Lake.

The origins of NY 364 date back to the 1920s when the Middlesex–Potter segment was briefly part of NY 52, the predecessor to today's NY 245. NY 364 was assigned as part of the 1930 renumbering of state highways in New York, but initially went no farther west than Middlesex. North of Middlesex, what is now NY 364 was unnumbered south of North Vine Valley Road and part of New York State Route 21A from there to Canandaigua. NY 364 was extended north to meet NY 21A by the following year. NY 21A was eliminated and partially replaced with an extended NY 364 in the early 1940s.
