The Mid North is a region of South Australia, north of the Adelaide Plains, but not as far north as the Far North, or the outback. It is generally accepted to extend from Spencer Gulf east to the Barrier Highway, including the coastal plain, the southern part of the Flinders Ranges, and the northern part of the Mount Lofty Ranges. The area was settled as early as 1840 (South Australia settlement began in 1836) and provided early farming and mining outputs for the fledgling colony. Farming is still significant in the area, particularly wheat, sheep and grapevines. There are not currently any significant mining activities in the Mid North but interest has been shown in iron ore mining by Australian Tailings Group  in the area of Olary Creek.
The main indigenous group of the Mid North are the Ngadjuri people. There were disputes and conflicts between the white settlers and the Aborigines, particularly in the 1850s and 1860s, but Ngadjuri people remain in the area and hold native title rights over the area. The extreme south west of the Mid North region is a part of the traditional lands of the Kaurna people.
For the purposes of weather districts, the Mid North region is divided horizontally into "Flinders" for the northern portion and "Mid North" for the southern portion by the Australian Bureau of Meteorology. Towns for which forecasts are published by the bureau demonstrate major townships within the bounds of the region. In the northern portion forecasts are published for: Hawker, Port Augusta and Ororroo. Towns for which forecasts are published in the southern region are: Port Pirie, Jamestown, Crystal Brook, Clare, Roseworthy and Snowtown.
