List of ancient tribes in Illyria

This is a list of ancient tribes in the ancient territory of Illyria (Ancient Greek: Ἰλλυρία). The name Illyrians seems to be the name of a single Illyrian tribe that was the first to come into contact with the ancient Greeks, causing the name Illyrians to be applied to all people of similar language and customs. The locations of Illyrian tribes/peoples prior to the Roman conquest are approximate, as sometimes many wholly different locations are given by ancient writers and modern authors (as in the case of the Encheleans).
