List of Catholic dioceses


As of June 21, 2024, the Catholic Church comprises 3,172 ecclesiastical jurisdictions worldwide, including over 652 archdioceses and 2,250 dioceses. It also includes various other jurisdictions such as apostolic vicariates, apostolic exarchates, apostolic administrations, apostolic prefectures, military ordinariates, personal ordinariates, personal prelatures, territorial prelatures, territorial abbacies, and missions sui juris.
In addition, there are 2,100 titular sees, encompassing bishoprics, archbishoprics, and metropolitanates.
This structural list outlines how each diocese is organized within its ecclesiastical province, under the framework of episcopal conferences, grouped by continent or region.

Exempt Catholic Dioceses (directly subject to the Holy See)

These 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.
  • Military ordinariates are in pastoral charge of the troops of a state, but may be vested in a Metropolitan Archbishop, typically in the national capital.
  • Also generally exempt are the apostolic prefectures and apostolic vicariates, which tend to be temporary missionary dioceses, expected to become part of an ecclesiastical province when promoted to regular bishopric.
  • The Personal Ordinariates for former Anglicans are allowed to use the Ordinariate Use, which is counted as a variant usage of the Roman Rite.
  • Eastern Ordinariates are in pastoral charge of all Eastern Churches, of only those of Byzantine Rite or even just of the Armenian Rite, in one or more states of various Catholic churches without any proper diocese there, but are usually vested in a Latin Catholic Metropolitan Archbishop, often in the capital.
  • Disregarded are many episcopal or archiepiscopal prelates in the Roman Curia, as their dicasteries don't constitute dioceses, although many posts there require by law or custom a bishop or an archbishop, just as the Vatican's diplomatic posts in nearly every national capital.
