River in Belgium, Germany and Luxembourg

The Our (; uʁ, ) is a river in Belgium, Luxembourg and Germany. It is a left hand tributary of the river Sauer/Sûre. Its total length is
The source of the Our is in the High Fens in southeastern Belgium, near Manderfeld. It flows southwards, more or less along the German Belgian border, and after Ouren, along the German Luxembourg border. The historic town of Vianden lies on the Our. The Our empties into the Sauer in Wallendorf.

The river rises in the eastern Ardennes and western Eifel on Belgian soil. Its source near the village of Losheimergraben lies northeast of the Eichelsberg mountain (653 m) at 643 m near the B 265. Just a few hundred metres away is the source of the River Kyll. The Our initially follows the B 265, which is also the Belgian German state border. The river continues alternating between Belgium and Germany. From the tripoint by the Europa Monument between Ouren (B), Sevenig (D) and Lieler (L) it runs almost entirely on the German Luxembourg border until it reaches Wallendorf in Germany where it empties into the Sauer. It generally meanders from north to south. For the section where it runs along the German Luxembourg border the Our is a jointly managed condominium (the "Joint German Luxembourg Sovereign Area"). Unilateral sovereignty only begins at the respective shore. In its upper reaches between Germany and Belgium, the state border lies, as is normal on the thalweg of the river.

The Our is impounded north of Vianden by the Our Dam and forms the lower basin of the Vianden Pumped Storage Plant.
