The Salyes or Salluvii (Greek: Σάλυες) were an ancient Celto-Ligurian people dwelling between the Durance river and the Greek colony of Massalia during the Iron Age. Although earlier writers called them 'Ligurian', Strabo used the denomination 'Celto-ligurian' in the early 1st century AD. A Celtic influence is noticeable in their religion, which centred on the cult of the tête coupée ('severed head'), as well as in the names of their towns and leaders. During the 2nd century BC, the Salyes were most likely at the head of a political and military confederation that united both Gallic and Ligurian tribes.
During most of their early history, the Salyes were in conflict with the neighbouring Greek inhabitants of Massalia, and later on with their ally the Roman Republic, until the consul Gaius Sextius Calvinus sacked their hill-fort Entremont ca. 122 BC. Revolts against the Roman conquerors were crushed in 90 and 83 BC.
