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 municipal 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 2,775m high Jôf di Montasio, lies in Friuli Venezia Region of Italy. The Julian Alps cover an estimated 4,400 km² (of which 1,542 km² lies in Slovenia). They are located between Sava valley and Kanalska Dolina. They are divided into the Eastern and Western Julian Alps.

The Western Julian Alps cover a much smaller area, and are located mainly in Italy. Only the Kanin group lies in Slovenia. The main peaks by height are:
