Maupertuis Bay is located on the south-west of
Kangaroo Island in South Australia. The bay forms the mouth of Rocky River which rises from within
Flinders Chase National Park.
Maupertuis Bay was named after mathematician and philosopher Pierre Louis Maupertuis by the French explorer Nicolas Baudin.
On 24 April 1899, the Scottish barque
Loch Sloy was shipwrecked off the coast from Maupertuis Bay resulting in the death of all but three crew and passengers.
