New York State Route 15A (NY 15A) is a north–south state highway located in the western portion of New York in the United States. It serves as an easterly alternate route of NY 15, beginning in the Livingston County town of Springwater and ending 35.19 miles (56.63 km) to the north in the Monroe County city of Rochester. NY 15A meets U.S. Route 20A (US 20A) in the hamlet of Hemlock, US 20 and NY 5 in the village of Lima, and Interstate 390 (I-390) twice in Henrietta and Brighton. Its southern and middle sections traverse mostly rural areas, while the northernmost piece in Henrietta, Brighton, and Rochester passes through significantly more developed areas.

From 1927 to the late 1930s, modern NY 15 was part of NY 2. As a result, all of what is now NY 15A was originally designated as New York State Route 2A as part of the 1930 renumbering of state highways in New York. Two parts of the route were sub-standard at the time; however, those sections were rebuilt in the early and mid-1930s. NY 2 was supplanted by an extended US 15 in April 1939, at which time NY 2A was renumbered to NY 15A to match its parent's new designation.
