The Battle of Gergovia took place in 52 BC in Gaul at Gergovia, the chief town of the Arverni. The battle was fought between a Roman Republic army, led by proconsul Julius Caesar, and Gallic forces led by Vercingetorix. The Gauls won the battle.

The site is identified with Merdogne, now called Gergovie, a village located on a hill within the town of La Roche-Blanche, near Clermont-Ferrand, in south central France. Some walls and earthworks still survive from the pre-Roman Iron Age.

Vercingetorix had earlier been expelled from Gergovia. In winter 53 BC, whilst Caesar was gathering his forces for a strike against the Gauls, Vercingetorix attacked Gergovia. Caesar states that this left him with a difficult decision, between keeping his forces safe over the winter but showing Roman weakness in defending her allies the Aedui and thus losing their support, or bringing Vercingetorix to open battle but risking running out of supplies - he chose the latter.

Leaving two legions and all his baggage train behind in Agedincum, Caesar led the remaining legions to Gergovia's aid. His sieges of Vellaunodunum, Genabum and Noviodunum on route caused Vercingetorix to lift his siege and march to meet Caesar in open battle at Noviodunum, which Caesar won. Caesar then besieged and captured Avaricum and resupplied there.
