Mastic was a station stop along the Montauk Branch of the Long Island Rail Road. It was originally opened as Forge around 1882, and renamed Mastic around 1893. When Brookhaven Station was eliminated by the LIRR on October 6, 1958, Mastic station was one of two stations recommended for use as a substitute by the patrons of the now closed station. The other was Bellport Station. However, this substitute was short-lived because Mastic station finally closed on July 7, 1960 as the new Mastic-Shirley Station opened 7,010 feet west on the same date. The depot was razed in August 1960, despite efforts to keep it intact.
