New York State Route 109 (NY 109), also known as the Babylon–Farmingdale Turnpike, is a four-lane state highway on Long Island in New York in the United States. It runs from Farmingdale in the Nassau County town of Oyster Bay to the village of Babylon in Suffolk County. It runs mainly west-to-east in a northwest to southeast direction.
NY 109 begins at a fork in the road from NY 24's western segment (Conklin Street) in the Nassau County village of Farmingdale. It proceeds eastward as Fulton Street in Farmingdale, a four-lane commercial arterial through the town, passing multiple apartment buildings. At Main Street, a median starts developing in the center, diving NY 109 as it crosses through a residential section of Farmingdale. Soon crossing back into the town of Oyster Bay, the route parallels the Central Branch of the Long Island Rail Road as it heads through town. After crossing into another large commercial district, this time in the village of East Farmingdale in the town of Babylon, Suffolk County, NY 109 enters a partial cloverleaf interchange with NY 110 (Broad Hollow Road).
