The Ningaloo Marine Park is an Australian marine park offshore of Western Australia, and west of the Ningaloo Coast. The marine park covers an area of 2,435 km2 (940 sq mi) and is assigned IUCN category IV. It is one of the 13 parks managed under the North-west Marine Parks Network.

Australian marine parks are marine protected areas located within Australian waters and are managed by the Australian government. These waters generally extend from three nautical miles off the coast to the outer limit of Australia’s Exclusive Economic Zone at 200 nautical miles while marine protected areas located closer in-shore are the responsibility of the states or the Northern Territory.
