This is a list of Saskatchewan's highways: Only Highways 1, 2, 5, 6, 7, 11, 12, 16, and 39 contain sections of divided highway. Speed limits range from 90 to 110 km/h. Saskatchewan is the only province bordering the United States with no direct connection to the Interstate Highway System.

Named routes

Primary (1–99)

These are primary highways maintained by the provincial government. Almost all of these highways are paved for most of their length. Highways 1, 11, and 16 are the most important highways and are divided highways for much of their lengths, with some sections at expressway or freeway standards.

Northern (100–199)

Major northern highways, usually corresponding to a "parent" 1-99 highway.

Secondary

200–299

These are usually highways connecting from a "parent" 1-99 highway to a recreational area.

300–399

These are usually highways connecting from a "parent" 1-99 highway to minor communities near the "parent" route.

Municipal roads

600–699

The 600-series highways are minor highways that run north and south; generally, the last two digits increase from east to west. Highway 600 is near the eastern border with Manitoba and Highway 699 is near the western border with Alberta. Many of these highways are gravel for some of their length.

700–799

The 700-series highways are minor highways that run east and west; generally, the last two digits increase from south to north. Many of these highways are gravel for some of their length.

Northern secondary (900–999)

These are roads that generally provide access to isolated, northern communities. Most of these highways are unpaved for their entire length.
