List of Catholic dioceses (structured view)

This is a structural list to show the relationships of each diocese to one another, grouped by ecclesiastical province, within each episcopal conference, within each continent or other geographical area.

These (arch)dioceses are exempt from belonging to any ecclesiastical province, hence only the Vatican can exert the authority and coordinating functions normally falling to the Metropolitan Archbishop.

Nevertheless, most belong to an episcopal conference, in which case the more relevant mention is in its geographical region, as exempt dioceses as such do not have specific ties with each other.

In addition, exempt, mixed ordinariates for the Eastern churches without dioceses of their own are established in a few (European and Latin American) countries, directly subject to the Holy See.
