The Diocese of Mariana and Acci or Diocese of Accia and Mariana (Latin: Dioecesis Acciensis et Marianensis) was a Roman Catholic ecclesiastical territory.
[2] The Diocese of Mariana was a Roman Catholic diocese seated in the Ancient Roman city of Mariana, Corsica.
Traditionally it was claimed to have existed already in the time of the apostles, but there is no evidence for that; the whole of Corsica was apparently Christianised by 439.
The title of Bishop of Mariana in Corsica continues in use.
