SS Clan Ranald was a two decked, turret deck ship, which sank on 31 January 1909 in the Australian state of South Australia off the coast of Yorke Peninsula near the town of Edithburgh. It is the only turret ship to have been lost in Australian waters, and therefore represents a unique part of Australia's maritime history. The bulk of crew were Asian sailors (lascars). Clan Ranald is considered one of the worst shipwrecks in South Australia (SA) where only 24 survived out of the 64 crew members.
