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.

Episcopal Conference of Vietnam (Hội đồng Giám mục Việt Nam), at Hồ Chí Minh City Ecclesiastical Province of Perth, covering Western Australia Ecclesiastical Province of Sydney, covering most of New South Wales Other Eastern eparchies (dioceses) See under § Episcopal Conference of Australia for the Chaldean Catholic, Melkite and Ukrainian Catholic dioceses competent for both countries, with sees in Sydney, Melbourne.

The West African subcontinent was previously covered by two language-distinct super-conferences: Neither country has or is part of any Latin Church province.

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.

This map visualizes the provinces of the Roman Catholic Church, as well as archdioceses (and other top-level entities) where provinces are not established.
