Co-Cathedral Of St. Alexander, Kyiv

A co-cathedral is a cathedral church which shares the function of being a bishop's seat, or ''cathedra'', with another cathedral, often in another city (usually a former see, anchor city of the metropolitan area or the civil capital). Instances of this occurred in England before the Protestant Reformation in the dioceses of 'Bath and Wells', and of 'Coventry and Lichfield'. These two dioceses were each named for both cities that served as bishop's seats.

As of March 2020, the Catholic Church had 322 co-cathedrals, mainly in Europe (140 in Italy alone).

Many are former cathedrals, but even if still in use, those often are not granted co-cathedral status.

Often the diocese with one or more co-cathedrals also has a multiple ("hyphenated") name reflecting these, but some have a co-cathedral not mentioned in the title while other former see titles may also be preserved without having a co-cathedral. Sometimes the first-named city does not have the main cathedral (actual see) but boasts another distinction such as being a national capital or having an august ecclesiastical past.

United Kingdom

Catholic Church

The Archdiocese of Liverpool includes a co-cathedral on the Isle of Man, the St. Mary of the Isle Church.

Church of England

Prior to the Protestant Reformation, the dioceses of 'Bath and Wells' and 'Coventry and Lichfield' were the only co-cathedrals in England.

Only one diocese of the Church of England has co-cathedrals; in the Anglican Diocese of Leeds there are three co-cathedrals, Ripon, Bradford and Wakefield. The Diocese of Leeds was formed in 2014 by the merger of the former Anglican dioceses of Bradford, Ripon, and Wakefield, with all three former diocesan cathedrals given co-equal status in the new diocese.

In the case of York the collegiate churches of Beverley, Ripon and Southwell were almost in the same position, but although the archbishop had a stall in each, he had no diocesan cathedra in them. The chapters were not united with that of the metropolitan church in the direct government of the diocese, or the election of the archbishop, nor had they those other rights which were held to denote the cathedral character of a church.

Scottish Episcopal Church

The Diocese of Argyll and The Isles of the Scottish Episcopal Church has two co-cathedrals: St John's Cathedral, Oban and Cathedral of The Isles, Millport, Cumbrae. It is the only diocese to have more than one cathedral.

North America

Catholic Church

In the United States, there are several instances in which a Roman Catholic diocese maintains two episcopal see cities, each with its own cathedral or co-cathedral. Examples include:
* the Cathedral of Saint Paul and the Basilica of Saint Mary in the Archdiocese of Saint Paul and Minneapolis (Minnesota).
* the Archdiocese of Roman Catholic Archdiocese of Galveston–Houston, Galveston–Houston (Texas),.
* the Archdiocese of Roman Catholic Archdiocese of Anchorage-Juneau, Anchorage-Juneau (Alaska).
* the Diocese of Roman Catholic Diocese of Altoona–Johnstown, Altoona–Johnstown (Pennsylvania).
* the Diocese of Roman Catholic Diocese of Fort Wayne–South Bend, Fort Wayne–South Bend (Indiana).
* the Diocese of Roman Catholic Diocese of Great Falls–Billings, Great Falls–Billings (Montana).
* the Diocese of Roman Catholic Diocese of Houma–Thibodaux, Houma–Thibodaux (Louisiana).
* the Diocese of Roman Catholic Diocese of Kansas City–Saint Joseph, Kansas City–Saint Joseph (Missouri).
* the Diocese of Roman Catholic Diocese of Pensacola–Tallahassee, Pensacola–Tallahassee (Florida).
* the Diocese of Roman Catholic Diocese of Springfield–Cape Girardeau, Springfield–Cape Girardeau (Missouri).
* the Diocese of Roman Catholic Diocese of Wheeling–Charleston, Wheeling–Charleston (West Virginia).
* the Diocese of Roman Catholic Diocese of Winona–Rochester, Winona–Rochester (Minnesota).

In some cases the co-cathedrals are in different municipalities, but the diocese's name does not reflect the dual cathedral status. For example:
* the Diocese of Roman Catholic Diocese of Trenton, Trenton (New Jersey) the cathedral, Cathedral of St. Mary of the Assumption (Trenton, New Jersey), St. Mary of the Assumption in Trenton, New Jersey, Trenton, and the co-cathedral, Co-Cathedral of St. Robert Bellarmine, St. Robert Bellarmine in Freehold Township, New Jersey, Freehold,
* the Melkite Greek Catholic Eparchy of Newton with its co-cathedrals, the Annunciation Melkite Catholic Cathedral in Boston, Boston, Massachusetts on the East Coast and the St. Anne Melkite Catholic Cathedral (North Hollywood, California) on the West Coast.

There are also three instances in the United States in which a cathedral and its co-cathedral are in the same city. This usually occurs when a historically important cathedral becomes too small to serve a growing population, and a larger co-cathedral is constructed to accommodate larger services. Examples include:
* The Cathedral Basilica of Our Lady of Peace and the Co-Cathedral of Saint Theresa of the Child Jesus (Honolulu, Hawaii), Co-Cathedral of Saint Theresa of the Child Jesus in the Roman Catholic Diocese of Honolulu, Diocese of Honolulu, Hawaii.
* The Cathedral of Mary Our Queen, Baltimore, Cathedral of Mary Our Queen and the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary (originally the cathedral and now the co-cathedral) in the Roman Catholic Archdiocese of Baltimore, Archdiocese of Baltimore, Maryland.
* The Cathedral Basilica of St. James (Brooklyn), Cathedral Basilica of St. James and the Co-Cathedral of St. Joseph (Brooklyn), Co-Cathedral of St. Joseph in the Roman Catholic Diocese of Brooklyn, Diocese of Brooklyn, New York.

Examples in Canada are:
* The Roman Catholic Archdiocese of Halifax-Yarmouth, Archdiocese of Halifax-Yarmouth, Nova Scotia, has the absorbed diocese's former see, St. Ambrose Co-Cathedral in Yarmouth, besides the Metropolitan's own cathedral Basilicas in the Catholic Church#Minor basilicas, minor basilica, St. Mary's Basilica (Halifax, Nova Scotia), St. Mary's Cathedral Basilica in Halifax.
* The Cathedral of Saint-Jean-l'Évangéliste and the Co-Cathedral of Saint-Antoine-de-Padoue in the Roman Catholic Diocese of Saint-Jean-Longueuil, Diocese of Saint-Jean-Longueuil, Quebec.
* Our Lady of Assumption Co-Cathedral in the former Gravelbourg Diocese, and the Holy Rosary Cathedral (Regina, Saskatchewan) both now in the Roman Catholic Archdiocese of Regina, in the province of Saskatchewan.
* The Holy Family Cathedral (Saskatoon), Holy Family Cathedral and St. Paul's Cathedral (Saskatoon), St. Paul's Cathedral in the Roman Catholic Diocese of Saskatoon, Diocese of Saskatoon, Saskatchewan.

Episcopal Church (United States)

In the Episcopal Church (United States), Episcopal Church in the United States, the Episcopal Diocese of Iowa, Diocese of Iowa and the Episcopal Church in Minnesota, Diocese of Minnesota each have two cathedrals, both located in different cities; however, they are not styled "co-cathedrals." The Episcopal Diocese of Lexington, Diocese of Lexington maintains a second cathedral of the Cathedral Church of St. George the Martyr at their Cathedral Domain conference center and camp in Irvine, Kentucky, but they do not use the term "co-cathedral" to describe it.
