Vivonne Bay (French: Baie Vivonne) is a bay in the Australian state of South Australia located on the south coast of Kangaroo Island about 61 kilometres (38 mi) from Kingscote, the island’s main town, and which was named by the members of Baudin expedition to Australia who visited the bay in January 1803. In a survey of 10,000 beaches by Professor Andrew Short, director of Sydney University’s marine studies centre, the beach at Vivonne Bay was adjudged as one of the best in Australia.
