The Corsi were an ancient people of Corsica and Sardinia, noted by Ptolemy (III, 3). They dwelt at the extreme north-east of the latter island, in the region today known as Gallura, near the Tibulati and immediately north of the Coracenses. The Corsi gave their name to the island of Corsica. According to the archeologist Giovanni Ugas, Corsi probably belong to the Ligurian people.
