List of Catholic dioceses in Italy


The following is the List of the Catholic dioceses in Italy., the Catholic Church in Italy is divided into sixteen ecclesiastical regions. While they are similar to the 20 civil regions of the Italian state, there are some differences. Most ecclesiastical regions are in turn divided into a number of ecclesiastical provinces. The provinces are in turn divided into a number of dioceses. The sovereign state of Vatican City is part of the metropolitan province of Rome. A metropolitan bishop exercises a degree of leadership over a group of dioceses that are loosely subject to the care of the metropolitan see. This list excludes those archdioceses, dioceses and ecclesiastical territories that are immediately subject to the Holy See.
There are 227 sees, most of which are dioceses led by a bishop. A diocese that is led by an archbishop is known as an archdiocese. There are 40 Metropolitan archdioceses which serve as the seat of an ecclesiastical province. This number includes the Holy See and the Patriarchate of Venice. There are also four archdioceses which are non-metropolitan, having been demoted by papal decree. This brings the number of archbishops in Italy and Vatican City to 44.
All the sees belong to the Latin Church apart from three Eastern Catholic sees of the Italo-Albanian Catholic Church that use the Byzantine Rite in the Albanian language. All sees of the Latin Church use the Roman Rite apart from the Metropolitan Archdiocese of Milan, which mainly uses the Ambrosian Rite.
In Rome, there is also an Apostolic Nunciature to the Republic of Italy and two permanent representatives to the Food and Agricultural Organization of the United Nations and to the International Institute for the Unification of Private Law.
