The Aedui or Haedui (Gaulish: *Aiduoi, 'the Ardent'; Ancient Greek: Aἴδουοι) were a Gallic tribe dwelling in the modern Burgundy region during the Iron Age and the Roman period.

The Aedui had an ambiguous relationship with the Roman Republic and with other Gallic tribes. In 121 BC, they appealed to Rome against the Arverni and Allobroges. During the Gallic Wars (58–50 BC), they gave valuable though not whole-hearted support to Caesar, before eventually giving lukewarm support to Vercingetorix in 52. Although they were involved in the revolts of Iulius Sacrovir in 21 AD and Vindex in 68 AD, their aristocracy became highly Romanized under the Empire.[1]
