The Battle of Vercellae, also known as the Battle of the Raudine Plain, was the decisive engagement that concluded the Cimbrian War. It took place on 30 July 101 BC on a plain near Vercellae in Gallia Cisalpina, located in modern-day Northern Italy.
The battle pitted a large Celtic-Germanic confederation led by the Cimbric king Boiorix against a Roman army. The Roman forces were under the joint command of the consul Gaius Marius and the proconsul Quintus Lutatius Catulus. The Roman victory effectively neutralized the threat posed by the migrating tribes and brought the long-standing conflict to an end.
