The Arverni (Gaulish: *Aruernoi) were a Gallic people dwelling in the modern Auvergne region during the Iron Age and the Roman period. They were one of the most powerful tribes of ancient Gaul, contesting primacy over the region with the neighbouring Aedui.
They are mentioned in 207 BC as treating with Carthaginian commandant Hasdrubal Barca. Headed by their chiefs Luernius and Bituitus, the Arverni were at the head of an extensive empire. After Bituitus was defeated by Domitius Ahenobarbus and Fabius Maximus in 121 BC, the Arvernian empire was reduced to suzerainty over some neighbouring tribes.
