Kongeå
The Kongeå (in German "Königs Au") is a watercourse in Southern Jutland in Jutland, Denmark. It rises southeast of Vejen and Vamdrup and after about it flows through a sluice to tidal mudflats and sandbanks north of Ribe, and eventually into the North Sea. The eastern section is little more than a stream, while the western section is navigable by boat as far as the sluice. The Kongeå, however, passes no port or market town of any significance, and small boats use Ribe Å.

Historically, the watercourse has been the administrative border between regions to the north and south. In the Middle Ages it was called "Skodborg Å" after the royal castle Skodborghus, where a track crossed the watercourse south of Vejen. For centuries a customs border near Kongeå separated the Kingdom of Denmark from the duchy of Schleswig. From 1864 to 1920, except in the extreme west, Kongeåen marked the border between Denmark and Germany.

The Kongeå is mentioned (as "Skotborg river") in the Heimskringla in a description of the 1043 battle in which King Magnus I of Norway and Denmark defeated at Lyrskov Hede ("Hlyrskog Heath") a large army of Slavs who had invaded southern Denmark from the current Mecklenburg region in retaliation for a Viking attack on Jomsborg, which at the time was the Slavic kingdom's primary town on Wolin island.
