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 as well as the two former counties of Vest-Agder and Aust-Agder. From New Year 2020, the two counties have been merged into one county, Agder. The total combined area of Vest-Agder and Aust-Agder counties is 16,493 square kilometres (6,368 sq mi). The name 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. The highest point in the region is Sæbyggjenuten at 1,507 m (4,944 ft).
