New York State Route 323 (NY 323) was a state highway in Erie County, New York, in the United States. The route was 5.24 miles (8.43 km) long and stretched from the town of Brant to the hamlet of Evans Center within the town of Evans. NY 323 began at an intersection with NY 249 and County Route 9 (CR 9) in Brant and headed north to a junction with NY 5 in Evans Center. In between, it passed over the New York State Thruway (Interstate 90 or I-90) and intersected U.S. Route 20 (US 20).

The route was assigned as part of the 1930 renumbering of state highways in New York. It went unchanged until 1980 when ownership and maintenance of the route was transferred from the state of New York to Erie County as part of a highway maintenance swap between the two levels of government. The designation was officially removed on August 14, 1980. The former routing of NY 323 is now the northern half of CR 9.

NY 323 began at an intersection with NY 249 and CR 9 north of the Cattaraugus Indian Reservation in Brant. The route headed northward as Brant–Angola Road through a rural area dominated by open fields and forests. It proceeded to the Brant–Evans town line, where it met Cain Road (CR 491) a short distance south of the New York State Thruway (I-90). The highway progressed onward, passing over the Thruway on its way to a junction with Dunfee Road, a connector leading to US 20. NY 323 met US 20 itself a short distance to the northwest.
