A cathedral or cathedral church (Latin ecclesia cathedralis "church of the cathedra"), also episcopal church, is a church in which a bishop resides and which contains the cathedra as his seat. As the principal and mother church of a diocese, it is the place from whose cathedra the local bishop performs the functions of preaching, liturgical ministry, and pastoral oversight associated with his office. The designation of a church as a cathedral does not imply any statement about the architectural style, the size or the time of origin of the building.

Cathedrals exist in episcopal churches such as the Roman Catholic Church, the Orthodox, Anglican and Old Catholic churches, and individual Lutheran and Methodist churches.

In the lists of cathedrals and cathedrals, cathedrals are listed by continent.
