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.
