Riverhead is a station along the Main Line (Greenport Branch) of the Long Island Rail Road.

The station house is owned by the Town of Riverhead and the MTA uses a high level platform and other amenities instead.

The station is also near the west end of the Riverhead Restoration Site of the Railroad Museum of Long Island.

A collection of historic Long Island Rail Road cars and maintenance equipment can be found near the station.
