Iron Knob is a town in the Australian state of South Australia on the Eyre Peninsula immediately south of the Eyre Highway. At the 2006 census, Iron Knob and the surrounding area had a population of 199.[9] The town obtained its name from its proximity to large deposits of iron ore, most notably Iron Monarch which outcropped prominently from the relatively flat, surrounding landscape.
