Alexander (Alessandro) Sauli, C.R.S.P. was an Italian priest who is called the "Apostle of Corsica". He is a saint of the Roman Catholic Church. In 1571, he was appointed by Pius V to the ancient see of Aléria, Corsica, where he rebuilt churches, founded colleges and seminaries, and, despite the depredations of corsairs, placed the Church in a flourishing condition.

Aléria is a commune in the Haute-Corse department of France on the island of Corsica, former bishopric and present Latin Catholic titular see. It includes the easternmost point in Metropolitan France.
