List of ancient cities in Illyria

This is a list of ancient cities in Illyria, towns, villages, and fortresses by Illyrians, Veneti, Liburni, Romans, Celts, Thracians, Dacians or Greeks located in or near Illyrian lands. A number of cities in Illyria and later Illyricum were built on the sites or close to the sites of pre-existing Illyrian settlements, though that was not always the case. Some settlements may have a double entry, e.g., Greek Pola and Roman Pietas Julia, and some toponyms are reconstructed.

A small part of the Roman province of Macedonia included Illyria Graeca, or Epirus Nova.

A very small part of the province of Italia included Istria.
