Udine  listen (help·info) (Friulian: Udin, Slovene: Videm, German: Weiden, Latin: Utinum) is a city and comune in northeastern Italy, in the middle of Friuli-Venezia Giulia region, between the Adriatic sea and the Alps (Alpi Carniche), less than 40 km from the Slovenian border. Its population was 100,032 in 2012, and that of its urban area was 176,000.

Udine is the historical capital of Friuli. The area has been inhabited since the Neolithic age, and was later, most likely, settled by Illyrians.

Based on an old Hungarian legend, Attila (?–453), the great hun emperor built a hill there, when besieging Aquileia, because he needed a winter quarters billet: he instructed his soldiers to bring soil in their helmet and shield, because, the landscape was too flat, without any hill. He established the town there, and built a square-shape tower.

After the fall of the Western Roman Empire, the area increased in importance after the decline of Aquileia and afterwards of Cividale also. In 983 AD Udine is mentioned for the first time, with the donation of the Utinum castle by emperor Otto II to the Patriarchs of Aquileia, then the main feudal lords of the region. In 1223, with the foundation of the market, the city became finally the most important in the area for economy and trades, and also became the Patriarch's seat.
