The Far North is a region that covers about 70 per cent of the Australian state of South Australia. It extends across the entire width of the state – about 1200 kilometres – for approximately the northernmost 750 kilometres. The state government defines the Far North region similarly, although it separately delineates the Maralinga Tjarutja Lands, the Yalata Aboriginal community and other unincorporated crown lands in the state's far west, which are officially considered part of the Eyre and Western region. Colloquially, South Australians regard anywhere north of Port Augusta as the Far North.

The Eyre Peninsula is a triangular peninsula in South Australia. It is bounded by the Spencer Gulf on the east, the Great Australian Bight on the west, and the Gawler Ranges to the north.
