Cape Wiles is a headland located on the west side of the southern tip of Eyre Peninsula in South Australia about 27 kilometres (17 miles) south west of the city of Port Lincoln.

The cape is described by one source as being the south east extremity of “a broad promontory” of which Cape Carnot is the south west extremity at a distance of 3 nautical miles (5.6 kilometres; 3.5 miles) to the west.

He left the ship in Jamaica and became gardener at a public nursery, then Island Botanist.

Since 2012, the waters adjoining its shoreline are within a habitat protection zone in the Thorny Passage Marine Park.
