Teurnia (later Tiburnia) was a Roman city (municipium). Today its ruins lie in the western Austrian state of Carinthia. In late antiquity it was also a bishop's see (today being a Catholic titular see), and towards the end of Roman times it was mentioned as the capital of the province of Noricum mediterraneum.
