Ras Nouadhibou (Arabic: رأس نواذيبو) is a 60-kilometre (37 mi) peninsula or headland divided by the border between Mauritania and Western Sahara on the African coast of the Atlantic Ocean.

It is internationally known as Cabo Blanco in Spanish or Cap Blanc in French (both meaning "White Headland").

Vagrants could be found as far south as Gambia and the Cape Verde islands, and as far north as continental Portugal and Atlantic France.

[5] Today, the cape hosts the largest surviving single population of the species, and the only remaining site which still seems to preserve a colony structure.

These fishing activities have had a negative impact on wildlife and caused the disappearance or endangerment of many species of marine mammals and birds.
