The Bellunes Alps (German: Belluneser Alpen, Italian: Prealpi Bellunesi) is the now obsolete name of a mountain range on the southern edge of the Eastern Alps. They lie in the Italian regions of Venetia and Trentino-South Tyrol. They cover the provinces of Treviso, Pordenone and part of Vicenza. The name is derived from the town of Belluno. Their highest peak is Col Nudo at 2,472 m s.l.m.. They are part of the Southern Limestone Alps, and are mainly made of the chalk limestone of the Southern Alps with summit region made of main dolomite.
