The Capu Biancu is a mountain in the department of Haute-Corse on the island of Corsica, France.

Capu Biancu is on a ridge that forms the boundary between the communes of Asco and Corscia in Haute-Corse.

The Ruisseau de Ghieriosa rises to the west of the Capu Biancu.

The peak may be accessed from Asco through the Pinara Valley or from the village of Corscia on the Nolo side.

The route from Corscia follows the road and then a marked trail past the Funtana di Callaiola to the Bergerie Caracuto, and then a line of cairns to the lake of Occihi Neri.
