Adelaide Dolphin Sanctuary (ADS) is a marine protected area in the Australian state of South Australia located on the east coast of Gulf St Vincent in and adjoining the north-western part of the Adelaide, covering the estuary of the Port River around Port Adelaide and northwards past St Kilda. It was established in 2005 for the protection of a resident population of Indo-Pacific bottlenose dolphins (Tursiops aduncus). The dolphins are keenly watched by dolphin enthusiasts, as well as being a tourist attraction, touted as the only city in the world with wild dolphins living in it.
