Cape Jervis is located at the south–west end of the Fleurieu Peninsula on the South Australian mainland. The cape is opposite Penneshaw, which is on the north-eastern end of Kangaroo Island, and the two are separated by Backstairs Passage. Matthew Flinders named the cape on 23 March 1802 after John Jervis, the first Earl of St Vincent, who had a distinguished career in the Royal Navy.
