List of Catholic dioceses (structured view)

As of June 21, 2024, the Catholic Church in its entirety comprises 3,172 ecclesiastical jurisdictions, including over 652 archdioceses and 2,249 dioceses, as well as apostolic vicariates, apostolic exarchates, apostolic administrations, apostolic prefectures, military ordinariates, personal ordinariates, personal prelatures, territorial prelatures, territorial abbacies and missions sui juris around the world.
In addition to these jurisdictions, there are 2,100 titular sees (bishoprics, archbishoprics and metropolitanates).
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.
This refers to Catholic dioceses in the world, of all Latin or Eastern churches, as of 5 October 2021.
Additional types, exclusively for the Eastern Churches, Ordinariate Use and Extraordinary Form
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. They are grouped here geographically. 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.
There are also 'meetings of episcopal conferences' for the (arch)bishops from countries belonging to:
(The ecclesiastical provinces' corresponding administrative regions are mentioned in parentheses) For overseas French dioceses, see under their continents and Episcopal conferences of Antilles (Central America) and Pacific (Oceania)
Scandinavian Bishops Conference
Swiss Bishops Conference
Note: The United States Conference of Catholic Bishops (USCCB) divides the non-exempt dioceses of the United States (including Alaska, Hawaii, and the U.S. Virgin Islands) into fourteen geographical regions—termed "Bishops' Regions" for the Latin Church provinces—and a fifteenth "region" that consists of the Eastern Catholic eparchies. These regions are not the canonical "ecclesiastical regions" described in canon 433 and 434, but are operated by an elected regional chairman. However, the Ordinaries of Personal Ordinariates established under the auspices of Anglicanorum Coetibus are members of their respective Bishops’ Conferences, and the USCCB lists the exempt Personal Ordinariate of the Chair of St. Peter as a part of Bishops’ Region X.
This is not a geographical region and it does not consist of ecclesiastical provinces. Instead, it consists exclusively of US branches of various, generally Europe- or Asia-based, particular Eastern Catholic Churches. See the Eastern Catholic Churches section (below) for their particular hierarchies.

The West African subcontinent was previously covered by two language-distinct super-conferences:

The 23 Eastern Catholic Churches retain many Orthodox traditions, even in the hierarchic terminology, such as calling dioceses Eparchies and archdioceses Archeparchies.
Their respective diocesan structures overlap with and are partially parallel to each other, to the Latin Church, often 'sharing' a see. 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.
They are presented grouped per ancient rite, or liturgical tradition. Following the name of each Church is given the nature of their ecclesiastical polity; for instance, whether it is headed by a Patriarch, a Major Archbishop, a Metropolitan Archbishop, or has no unified structure and is instead composed of jurisdictions each individually subject to the Holy See.
In the Arab World and Africa, the church has dioceses in:
Throughout the rest of the world, the Melkite Catholic church has dioceses and exarchates for its diaspora in:
Furthermore, one of the Ordinaries is appointed Apostolic visitor for the countries without proper ordinariates in Western Europe, while in some countries the Melkite diaspora is served pastorally by an Ordinariate for Eastern Catholic faithful.
