Monte Stello (or Monte Stellu) is a mountain in the department of Haute-Corse on the island of Corsica, France. It is the second highest point in the Monte Stello massif, which forms the backbone of Cap Corse.

The peak is roughly at the intersection of the borders of the communes of Olcani to the northwest, Olmeta-di-Capocorso to the west and Brando to the east. It is east of the village of Olmeta-di-Capocorso and west of the village of Erbalunga on the east coast.

Monte Stello has a prominence of 347 metres (1,138 ft) and an elevation of 1,306 metres (4,285 ft). It is isolated by 5.1 kilometres (3.2 mi) from the 1,324 metres (4,344 ft) Cima di e Follicie to the north northwest.

Monte Stello consists of Cretaceous ophiolites that were formed during the Alpine orogeny.

The trail from the hamlet of Pozzo has a total ascent of about 1,000 metres (3,300 ft). It is long and takes about six and a half hours to complete, but is well-marked and not technically demanding. It runs through maquis shrubland. From the summit there is an excellent panorama of the north of Corsica.
