The Julian Alps are a mountain range of the Southern Limestone Alps that stretch from northeastern Italy to Slovenia, where they rise to 2,864 m at Mount Triglav, the highest peak in Slovenia and of the former Yugoslavia. They are named after Julius Caesar, who founded the municipium of Cividale del Friuli at the foot of the mountains. A large part of the Julian Alps is included in Triglav National Park. The second highest peak of the range, the 2,775 m high Jôf di Montasio, lies in Italy.
The Julian Alps cover an estimated 4,400 km2 (of which 1,542 km2 lies in Italy). They are located between the Sava Valley and Canale Valley. They are divided into the Eastern and Western Julian Alps.
