Southern Jutland (Danish: Sønderjylland; German: Südjütland) is the name for the region south of the Kongeå in Jutland, Denmark and north of the Eider (river) in Schleswig-Holstein, Germany. The region north of the Kongeå is called Nørrejylland, 'Northern Jutland'. Both territories had their own ting assemblies in the Middle Ages (in Viborg and Urnehoved). Southern Jutland is mentioned for the first time in the Knýtlinga saga.
