Pizzo Berro, Mountain summit in the Sibillini Mountains, Italy.

Pizzo Berro is a 2,259-metre mountain in the central Sibillini group, on the border of Montefortino, Ussita and Castelsantangelo sul Nera. A long north-south crest rises from Forcella Angagnola to the summit, where large slabs of massive limestone break through high-altitude pastures. The peak lies on the east-west ridge linking the Priora massif to Monte Bove.

The mountain has served as a natural boundary between the Marche and Umbria regions since medieval times. This geographic division shaped the territory for centuries and continues to be reflected in current provincial boundaries.

The name Pizzo Berro probably comes from "verro" or "guerro", echoing the steep slopes' impetuosity; the origin remains uncertain. The summit's massive limestone plates break through green high-altitude pastures, a detail walkers notice along the north crest.

The summit can be reached by the north ridge trail from Forcella del Fargno, or from Forca della Cervara via an exposed path from Monte Bove Sud, using a short via ferrata below the top to cross the rock buttresses. In winter it becomes a demanding winter mountaineering objective, ringed by ice cornices, requiring solid winter climbing experience.
