Cardinal regions

The province is regularly divided into three regions of Northern, Central, and Southern Saskatchewan, the latter two of which include the subregions of East-Central, Southeast, Southwestern, and West-Central Saskatchewan.^[5][6][7] Along with these regions, the terms Northwestern and Northeastern Saskatchewan may be used to refer to the furthest north reaches of Central Saskatchewan; or, less often, they may be used to divide Northern Saskatchewan into two.

• Northern Saskatchewan, the northern half of the province, mostly uninhabited, with its southern boundary often defined near Prince Albert and the start of the boreal forest.
• Central Saskatchewan, the part of the province located between Northern and Southern Saskatchewan, including Saskatoon and the most densely populated parts of the province, with its northern boundary often defined at the boreal forest tree line and its southern boundary at Lake Diefenbaker and the Qu'Appelle Valley.
  • East-Central Saskatchewan, centred around Hudson Bay and Yorkton.
  • West-Central Saskatchewan, centred around Kindersley and the Battlefords.
• Southern Saskatchewan, the southernmost portion of the province, including Moose Jaw, Regina, and Swift Current, with its northern boundary often identified at Lake Diefenbaker and the Qu'Appelle Valley.
