Speonk is an unstaffed railroad station on the Montauk Branch of the Long Island Rail Road. It is located on Phillips Avenue at Depot Road in Speonk, New York, just north of Montauk Highway. The station has two parking lots, one operated by the Long Island Rail Road, and the other operated by the Town of Southampton, both of which are free. It also lies adjacent to one of the largest railroad yards on Long Island's East End. This yard is mostly used to hold passenger consists, as a handful of trains terminate at Speonk rather than continue all the way to Montauk.
