New York State Route 25A (NY 25A) is a state highway on Long Island in New York, United States. It serves as the main east–west route for most of the North Shore of Long Island, running for 73 miles (117 km) from Interstate 495 (I-495) at the Queens–Midtown Tunnel in the New York City borough of Queens to NY 25 in Calverton, Suffolk County. The highway is a northern alternate route of NY 25, which follows a more inland routing along Jericho Turnpike.
The route is known for its scenic path through decidedly lesser-developed areas such as Brookville, Fort Salonga, Centerport, and Roslyn. It is known by various names along its routing, the most prominent of which include Northern Boulevard, North Hempstead Turnpike, Main Street, Fort Salonga Road, and North Country Road. It merges with NY 25 for approximately 1.5 miles (2.4 km) in Smithtown.
