The Roman Catholic Diocese of Annecy, (Lat: Dioecesis Anneciensis) is a diocese of the Latin Rite of the Roman Catholic church in France. Originally erected in 1822, after the Concordat as a subdivision of the Roman Catholic Archdiocese of Chambéry, the diocese comprises the entirety of the department of Haute-Savoie in the Region of Rhône-Alpes. Only recently, in 2002, did the metropolitan change. The diocese is now suffragan to the Archdiocese of Lyon.
