Sør-Trøndelag in the context of "Nord-Trøndelag"

Trøndelag (Urban East Norwegian: [ˈtrœ̂ndəˌlɑːɡ]; or Trööndelage (Southern Sami) is a county in central Norway, coextensive with the Trøndelag region (also known as Midt-Norge or Midt-Noreg, lit. "Mid-Norway"). It was created in 1687, then named Trondhjem County (Norwegian: Trondhjems Amt); in 1804 the county was split into Nord-Trøndelag and Sør-Trøndelag by the King of Denmark-Norway. After over two centuries of separation, in 2018 they were reunited following a referendum held two years earlier.

The largest city in Trøndelag is the city of Trondheim. The administrative centre is Steinkjer, while Trondheim functions as the office of the county mayor. Both cities serve the office of the county governor; however, Steinkjer houses the main functions.

Norway is commonly divided into five major geographical regions (landsdeler). These regions are purely geographical and cultural, and have no administrative purpose. However, in 2017 the government decided to abolish the current counties of Norway (fylker) and to replace them with fewer, larger administrative regions (regioner). The first of these new areas came into existence on 1 January 2018, when Nord-Trøndelag and Sør-Trøndelag merged to form Trøndelag.

According to most definitions, the counties of Norway are divided into the following regions (these groupings are approximate):
