Hawker is a town and a locality in the Flinders Ranges area of South Australia, 365 kilometres (227 mi) north of Adelaide.

Portions of Hawker were added to the adjoining localities of Flinders Ranges and Shaggy Ridge on 26 November 2013.

While most of Hawker remained simply pegged-out blocks of bluebush, the 'top end' of the town, where business activity was concentrated, must have been as animated as an ant colony.

Constantly teams of horses, bullocks, donkeys, and even camels converged upon, or radiated from, the town, raising the dust in that dry year of 1880.

"[6] Hawker has a number of heritage-listed sites, including: The main economic activities in the area are tourism and pastoral runs of sheep and increasingly cattle.
