Aedui (ĕ´dyōōī) or Haedui (hĕ´dyōōī), Gallic people, occupying in the 1st cent. BC a part of what later became Burgundy. Defeated by Ariovistus and at odds with their Gallic neighbors, they were allies of the Romans. The Aedui at first aided Julius Caesar in the Gallic Wars and later were not wholehearted in their support of Vercingetorix's revolt against Caesar. Their early capital was Bibracte.
