New York State Route 111 marker

New York State Route 111 (NY 111) is a state highway located in Suffolk County, New York, in the United States. It runs north–south for 9.42 miles (15.16 km) through the towns of Islip and Smithtown, connecting NY 27A in the town seat of Islip to the east end of the NY 25 and NY 25A concurrency in Smithtown's Village of the Branch. Most of the road is a two-lane highway, save for several short four-lane stretches in the vicinity of interchanges along the route. NY 111 was assigned as part of the 1930 renumbering of state highways in New York as an East Islip–Village of the Branch highway, using what is now County Route 17 (CR 17) south of Hauppauge. It was realigned to serve the hamlet of Islip in 1966.

NY 111 begins at an intersection with NY 27A (Main Street) in the town of Islip. The route proceeds north through the hamlet of Islip along the two-lane Islip Avenue, passing through a short residential stretch ahead of an intersection with CR 50 (Union Boulevard). NY 111 soon crosses the nearby Montauk Branch of the Long Island Rail Road just east of the Islip station, from where it continues north past various businesses and residences. As the road heads northward, it intersects with Bittermint Street, a connector to NY 27 (Sunrise Highway) eastbound. After crossing over NY 27, the route intersects with a ramp serving the westbound lanes and Islip Boulevard, which connects NY 27 westbound to NY 111.
