Since time immemorial, Wudinna has been part of the country visited from the east coast of Eyre Peninsula, seasonally and for ceremonial and special purposes, by the Barngarla people. The Barngarla name is "Woodina", meaning "granite hill". The area was first settled by Europeans in 1861, after Robert George Standley lodged a claim for 10 square kilometres of land surrounding what was then referred to as Weedna Hill.
