The Redones or Riedones (Gaulish: Rēdones, later Riedones, 'chariot- or horse-drivers') were a Gallic tribe dwelling in the eastern part of the Brittany peninsula during the Iron age and subsequent Roman conquest of Gaul. Their capital was at Condate, the site of modern day Rennes. In 57 BC they were subjugated by the Romans under forces led by Publius Licinius Crassus, the son of the triumvir Marcus Licinius Crassus, but they provided men to the Gallic coalition led by Vercingetorix at the Battle of Alesia in 52.
