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).[1]
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.

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.[4][5]
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.[citation needed]
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:
There are also three instances in the United States in which a cathedral and its co-cathedral are in the same city.[8] 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:
In the Episcopal Church in the United States, the Diocese of Iowa and the Diocese of Minnesota each have two cathedrals, both located in different cities; however, they are not styled "co-cathedrals." The 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.[9]
