Monte Bo (or Cima di Bo) is a mountain in the Alpi Biellesi, a sub-range of Pennine Alps.

The mountain is located between Sessera and Cervo valleys and is totally included in the province of Biella. It is divided between the comune of Piedicavallo and the mountain exclaves of Pettinengo, Tavigliano and Valle San Nicolao.

According to the SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain can be classified in the following way:

• main part = Western Alps
• major sector = North Western Alps
• section = Pennine Alps
• subsection = Southern Valsesia Alps
• supergroup = Alpi Biellesi
• group = Catena Tre Vescovi - Mars
• subgroup = Costiera Bo-Cravile-Monticchio
• code = I/B-9.IV-A.2.b

With an elevation of 2,556 m, it is the second highest peak of the Province of Biella after Monte Mars (2,600 m).

The easiest route for the summit is a long but well marked footpath starting from Montesinaro, a village belonging to Piedicavallo township. Nearby the mountain's top is located Bivacco Antoniotti, an emergency mountain shelter.

The summit of the Bo is a well known hiking destination, and since the 19th century it has been celebrated because:

• It commands a vast and varied panorama of the Alps and plains, which has been engraved by the Italian Alpine Club.
