Southern Norway (; 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 .  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 .

Etymology
Sørlandet refers to the region along the Skaggerak in southeastern Norway.  This name should not be confused with the Norwegian term Sør-Norge which literally means South Norway (as opposed to North Norway).   This region was historically called Agder and it was a petty kingdom centuries ago.  The name Agder was known in Old Norse as "Agðir", and is assumed to be connected to the word ǫgd (sharp).

History
Southern Norway is the "youngest" of the many old regions within Norway; it was established shortly after the region of Northern Norway. The name Sørlandet was first used by the author Vilhelm Krag.  Krag proposed that Sørlandet should have been bigger than it is today, he suggested from Egersund to Grenland.  The present day use of Sørlandet usually refers to an area smaller than that, but there is no official border. All the way back in 1865, it was talked about "the southern Norway boats".

The name and modern concept of this part of the country being considered as a separate region was introduced as late as 1902 by the local author Vilhelm Krag. Prior to this, the area was considered part of Western Norway. Southern Norway coincides roughly with the historic petty kingdom of Agder, which lends its name to the two constituent counties: Vest-Agder and Aust-Agder, as well as the University of Agder.

If defined as an informal region, Southern Norway is perhaps more properly defined as the Skagerrak coastal belt, thus excluding the inland valleys to the north.  Occasionally, adjacent parts of the county of Rogaland and Telemark might be considered part of this region, as well.

Traditionally, the easternmost border of Agder was Rygjarbit, which was thought to be Gjernestangen in the present-day municipality of Risør, but it could also be the strait between Askerøya and Lyngør in Tvedestrand.

Economy
Key industries in Southern Norway are forestry, agriculture, and tourism.  Tourism is very important in the summer due to the mild climate as well as the winter with its good skiing conditions.  There are popular ski resorts like Hovden in the Setesdal valley as well as Bortelid in Åseral municipality.  The farms in this region are generally small due to the topography.  Dairy farming is the largest agricultural use, predominantly in Vest-Agder.  The interior areas of the region tend to have more sheep farming than dairy.  The most productive forests are in the interior of the region as well.  The fishing industry is not very large in this region, but it does exist.  Hydroelectric power generation is also a larger part of the economy in this region with many power stations on most of the larger river systems throughout the region.
