The Col de Santo Stefano[a] Corsican: Bocca di San Stefanu) is a mountain pass in the Haute-Corse department of Corsica, France.

The Santo Stefano pass is located in "Schist Corsica" in the northeast of the island, south of the Serra where, as Agostino Giustiniani writes, "this mountain chain which runs along the length of Cap Corse enters the Nebbio and extends to a rural church called S. Stefano, in the pieve of Rosolo, one of the three pieves of the Nebbio".

[3] On the eastern side of the pass, is the defile of Lancone in the gorges of which the Bevinco river flows, skirted on its left bank by the road D62.

Located 368 metres (1,207 ft) above sea level, to the east of the Nebbio basin, it is little affected by the strong westerly winds that sweep the Agriates and the Gulf of Saint-Florent.

On 9 October 1768 all the available French troops left Bastia to go to the aid of the Borgu garrison, while Grandmaison attacked at Olmeta to create a diversion.

After liberating Rutali on 29 September, the next day at dawn after a fierce fight the Moroccan skirmishers of Captain Morand reached the pass and captured the eleven surviving S.S.
