The Fleurieu Peninsula (FLOO-ree-oh) is a peninsula located south of Adelaide in South Australia, Australia. It was named after Charles Pierre Claret de Fleurieu, the French explorer and hydrographer, by the French explorer Nicolas Baudin as he explored the south coast of Australia in 1802. The name came in official use in 1911 in response to a recommendation to the South Australian Government from the Royal Geographical Society of South Australia following a representation from Count Alphonse de Fleurieu, a great-nephew of Charles de Fleurieu, that places in South Australia discovered by but unnamed by Matthew Flinders be given the names proposed by Baudin's expedition.
Towns of interest in the area include Victor Harbor, Willunga, Mount Compass, Normanville, Goolwa, Yankalilla and Rapid Bay. Districts include Inman Valley and Hindmarsh Valley. There is surfing on both the west and south facing coasts - known locally to Adelaide surfers as the Mid South Coast and the Far South Coast. Surf spots of note include Waitpinga and Middleton on the Far South Coast. A ferry travels between Cape Jervis, at the tip of the peninsula, and Kangaroo Island. The south part of the wine region of McLaren Vale located within the Peninsula.
