New York State Route 31A (NY 31A) is an east–west state highway located in the western part of New York in the United States. It serves as a southerly alternate route of NY 31 from the western part of Orleans County to the far western part of Monroe County. It diverges from NY 31 south of the village of Medina and parallels NY 31 eastward until it reconnects to its parent route southwest of the village of Brockport. While NY 31 passes through the villages of Medina, Albion, and Holley, NY 31A bypasses all three, serving sparsely populated areas to their south instead. The route intersects NY 98 south of Albion and NY 237 in Clarendon.

The origins of NY 31A date back to the 1930 renumbering of state highways in New York when the section of modern NY 31 between Middleport and Medina was designated as New York State Route 3A. It was renumbered to New York State Route 3B c. 1932 and extended northeastward to Knowlesville via Millville by 1932 before becoming NY 31A c. 1935. The section of modern NY 31 and NY 31A from NY 19 in Brockport to Clarendon was designated as New York State Route 3B in 1930, but was renumbered to New York State Route 3C c. 1932 and the west end was cut back to the Monroe–Orleans county line before becoming New York State Route 31D c. 1935. NY 31A was cut back to its current western terminus in 1949 and extended eastward to NY 19 and NY 31 in Brockport c. 1963, replacing NY 31D. The route was truncated to its current eastern terminus in the early 1980s after NY 31 was altered to bypass Brockport to the southwest.
