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).
After the Great Illyrian Revolt, the Romans deported, split, and resettled Illyrian tribes within Illyria itself and to Dacia, sometimes causing whole tribes to vanish and new ones to be formed from their remains, such as the Deraemestae and the Docleatae, some of them mixed with Celtic tribes (see Celticization). Many tribal names are known from Roman civitates and the number of their decuriae, formed of the dispersed tribes in Illyria.
Albani or Albanoi (Greek: Ἀλβανοί) were an Illyrian tribe whose first historical account appears in a work of Ptolemy. They were the citizens of Albanopolis (Ἀλβανόπολις), located in the center of modern Albania, in the Zgërdhesh hill fort, near the city of Krujë. The national ethnonym of the Albanians is derived from this tribe.
Ardiaei or Ouardiaei (Greek Ἀρδιαῖοι or Οὐαρδαῖοι; Latin Vardiaei), was an Illyrian tribe, residing inland, that eventually settled on the Adriatic coast. The Ardiaei had 20 decuriae. The Ardiaean dynasty ruled over the Illyrian Kingdom.
