New York State Route 24 (NY 24) is an east–west state highway on Long Island in New York in the United States. The route is split into two segments, with the longest and westernmost of the two extending from an intersection with Interstate 295 (I-295, named the Clearview Expressway) and NY 25 (Hillside Avenue) in the Queens Village section of the New York City borough of Queens to a junction with NY 110 in East Farmingdale in the Suffolk County town of Babylon. The shorter eastern section, located in eastern Suffolk County, runs from an interchange with I-495 in Calverton to an intersection with County Route 80 (CR 80) in Hampton Bays.
NY 24 is one of three routes in New York that is split into two segments; the others are NY 42 in the Catskills and NY 878 in Queens and Nassau County. Like NY 42, NY 24 was a continuous route when it was assigned as part of the 1930 renumbering of state highways in New York. The route was split into two pieces in the mid-1930s. For a brief period during the late 1950s and early 1960s, NY 24 was routed on the Long Island Expressway from Manhattan to East Hills while its original surface routing was designated New York State Route 24A.
