Hillside, earlier Rockaway Junction, was a junction and station on the Long Island Rail Road's Main Line and Montauk Branch in Hillside, Queens, New York City, United States. It was located at the place where the Montauk Branch now crosses over the two eastbound passenger tracks and the two freight tracks of the Main Line, just west of the Hillside Facility. The junction was formed in 1871, when the LIRR's Rockaway Branch was built south from the Main Line.
