The Diocese of Ajaccio (Latin: Dioecesis Adiacensis; French: Diocèse d'Ajaccio) is a Latin Church ecclesiastical jurisdiction or diocese of the Catholic Church in France. The diocese comprises the whole of the island of Corsica.
Erected in the 3rd century, the diocese was formerly a suffragan of the Archdiocese of Pisa. After the French Concordat of 1801, the diocese became a suffragan of the Archdiocese of Aix-en-Provence and Arles, until 2002 when it was attached to the archdiocesan province of Marseille. In 2012, in the diocese of Ajaccio, there was one priest for every 3,636 Catholics.
