New York State Route 231 (NY 231) is a 9.05-mile (14.56 km) long state highway located in Suffolk County, on Long Island, in New York, in the United States. The route extends north–south from a partial interchange with NY 27A in the Incorporated Village of Babylon to an interchange with the Northern State Parkway in Dix Hills.

The southernmost 2 miles (3.2 km) of NY 231 is an expressway known simply and only as Route 231. This section of the road was originally built to be part of the Babylon–Northport Expressway, a failed highway project that was never completed.[4] The remainder of NY 231 is part of Deer Park Avenue.[5]
