Cambridge Gulf is a gulf on the north coast of the Kimberley region of Western Australia.Many rivers flow into the gulf, including the Ord River, Pentecost River, Durack River, King River and the Forrest River, making the environment an estuarine one. The gulf experiences two large tidal flows each day between 7 and 9 metres (23 and 30 ft). The entrance of the Gulf is defined by Cape Domett on the eastern shore, Lacrosse Island in the middle, and the Cape Dussejour on the western shore, with King Shoals and Medusa Banks out in Joseph Bonaparte Gulf beyond Lacrosse Island.
