The Deciates (Δεκιῆται) were a Ligurian tribe in the first few centuries BC. They lived in the Antibes area of what is now France, west of the river Var (Smith, entry on Deciátes; Cosson, pp. 20–23). The border with the Ligurian Oxybii (Ὀξύβιοι) being to the west of Antipolis and east of Forum Julii (Smith, entry on Oxybii). The Deciates had a town in the area, oppidum Deciatum but this was not Antibes itself (Pliny the Elder, Chorographia, 2.69):
- In litoribus aliquot sunt cum aliquis nominibus loca: ceterum rarae urbes quia rari portus, et omnis plaga austro atque africo exposita est. Nicaea tangit Alpes, tangit oppidum Deciatum, tangit Antipolis.
