Rapid Bay features in the
creation myths of the
Kaurna and
Ramindjeri peoples most notably as the burial site of the nephew of the Kaurna
creator ancestor known as
Tjilbruke. There is uncertainty as to the Kaurna name for Rapid Bay, which has been cited as Patparno, Patpangga (meaning "south" or "south place"), and Yarta-kulangga, a popular campsite at Rapid Bay, whose name probably means "place of the separate country". However, there is no evidence that any of these names was a place name for Rapid Bay, though the bay is officially dual-named
Patpangga. Prior to the establishment of the South Australian colony,
whalers based on
Kangaroo Island were known to have called at Rapid Bay though it was not so named until 1836. South Australia Colonial Surveyor General
Colonel William Light made his first landfall on mainland South Australia at Rapid Bay on 8 September 1836. The site was named after Light's ship, the 162 ton
brig Rapid. To mark this historic landfall the Colonel's initials, "W.L.", were carved into a large boulder – a replica is visible in the township, while the original is stored in the
South Australian Museum, in Adelaide. John Rapid Hoare (7 November 1836 – perhaps 7 July 1916), also named for the brig
Rapid, was the first European child born on mainland South Australia. Claims that he was born at Rapid Bay have been refuted. Rapid Bay was briefly considered by Light as a potential site for the new colony's capital, == Quarrying ==
