New York State Route 391 (NY 391) is a short state highway in Erie County, New York, in the United States. The route is signed as north–south; however, it follows more of a southeast–northwest alignment between NY 277 in the hamlet of North Boston and U.S. Route 62 (US 62) in the village of Hamburg. NY 391 meets the Southern Expressway (US 219) just north of North Boston. Both ends of NY 391 are located in residential areas; however, the middle section of the route passes through more rural areas of the towns of Boston and Hamburg.

The routing of NY 391 has been part of several routes over the years, beginning with NY 62 in 1930. NY 62 was mostly renumbered to NY 75 c. 1932, and all of NY 75 south of Hamburg became concurrent to US 219 when it was extended into New York c. 1935. NY 75 was cut back to Hamburg by 1940, leaving just US 219 on modern NY 391. US 219 was realigned north of North Boston in the early 1970s to follow other routes north to meet the first completed piece of the Southern Expressway near Orchard Park. NY 391 was assigned to US 219's former routing into Hamburg at this time. The route originally ended two blocks to the west at the junction of NY 75 and US 62; however, this extension was eliminated c. 2004.
