Monte Antelao (Cadorino dialect: Nantelòu) is the highest mountain in the eastern Dolomites (a section of the Alps) in northeastern Italy, southeast of the town of Cortina d'Ampezzo, in the region of Cadore.

As the highest pinnacle of the eastern Dolomites, the Antelao is not part of a closed massif or a high plateau, but a single, mighty rock pyramid.

When the weather is good, Monte Antelao is clearly visible from Trieste on the Adriatic Sea.

[2] It involves a good deal of exposure, and a few short technical sections, such as a chimney, protected by cables.

There is a refuge, the Rifugio Galassi, which is located below the Forcella Piccola in the upper Val d'Oten.
