Darke Peak (formerly Carappee) is a small agricultural town located in central Eyre Peninsula, South Australia.

The town takes its name from the explorer John Charles Darke, who was injured in a spear attack by Indigenous people while he was climbing nearby Waddikee Rock on 24 October 1844.

In 1865 surveyor Thomas Evans who was performing a trigonometrical survey of the Gawler Ranges and named the 1,564 ft (477 m) high mount, 'Darke's Peak'.

Darke's grave and monument are located on the western side of the range, still standing as a memorial to the first European who explored this area.

Darke Peak has a hotel which dates back to the early days of the settlement and offers accommodation and meals.
