Southern Norway

Southern Norway (Norwegian: Sørlandet; lit.'The Southland') is the geographical region (landsdel) along the Skagerrak coast of southern Norway. The region is an informal description since it does not have any governmental function. It roughly corresponds to the old petty kingdom of Agder being coextensive with the present-day county, as well as the two former counties of Vest-Agder and Aust-Agder (which existed until 2020). The total area is 16,435 square kilometres (6,346 sq mi) and there are about 319,850 residents living here as of 2025. The name Sørlandet is relatively new, having first been used in Norway around 1900.

The region includes coastal areas along the Skagerrak and extends inland to the Setesdalsheiene mountains. There are many large valleys running from the mountains to the south and east to the sea, including the notable Setesdal valley. The highest point in the region is Sæbyggjenuten at 1,507 m (4,944 ft).
