Williams Island is an island in the Australian state of South Australia located off the south coast of Jussieu Peninsula on Eyre Peninsula approximately 34 km (21 mi) south-east of Port Lincoln. It was named by Matthew Flinders for Robert Williams who subsequently lost his life along with seven other crew in the capsize of a cutter launched from HM Sloop Investigator to search for water on 21 February 1802. Since 2004, the island has been part of the Memory Cove Wilderness Protection Area.
