The Vrbas is a major river with a length of 250 kilometres, in western Bosnia and Herzegovina. It is a right tributary of the Sava river. The city of Banja Luka is located on the river banks.
The word vrba means “willow” in Bosnian, Serbian and Croatian, and a number of weeping willow trees adorn the river banks in Banja Luka.
It lent its name to one of the provinces (banovinas) of the Kingdom of Yugoslavia, the Vrbas Banovina.
