Gantry Park, viewed over the Dukes Bay.

Gantry Park is a large public park featured in Grand Theft Auto IV and Grand Theft Auto: Chinatown Wars. The park can be accessed by Dukes Drive, bordered to the west by the Dukes Cemetery, east by the Dukes Bay Bridge, and the banks of Dukes Bay to the north in Steinway, Dukes, Liberty City.

The open outdoor space contains a car park, baseball field, Trees, picnic area, wide boardwalk and boat wharves on the waterside. It is the largest park in Steinway, about twice the size of the nearby Steinway Park. It is based on the Gantry Plaza State Park, with the large gantry cranes reading "East Island" on the side facing the water, just like the real-life counterpart, which says "Long Island" in the same place.
