The Diocese of Accia was a Roman Catholic bishopric on the island of Corsica. It is now a titular diocese. The diocese was located in the town of Accia in the interior region of Haute-Corse, which was destroyed and from which only some ruins remain. Established in 824 AD it was merged with the Diocese of Mariana in 1554. In 1570 the Bishop of Mariana and Accia moved his seat to Bastia.
In 1968, the Diocese of Accia was revived as a titular See, and with one brief exception, has been used as a title for Auxiliary Bishops of various dioceses.
