Great River is a railroad station on the Montauk Branch of the Long Island Rail Road, at Connetquot Avenue and Hawthorne Avenue in East Islip, New York.

In 1945, a modernist station designed by architect Antonin Raymond replaced it,[3] but it was burned down in 2000.

The original shelter, however was restored by the East Islip Historical Society, and remains within one of the parking lots along the eastbound platform.

This station was located between Mileposts 45 and 46 inside today's Bayard Cutting Arboretum, and was among a number of privately-owned stations along the SSRRLI, which were not so uncommon during the 19th Century.

[4] The station has two tracks and two four-car long high-level side platforms.
