This is the list of cathedrals in Croatia sorted by denomination.

A cathedral church is a Christian place of worship that is the chief, or "mother" church of a diocese and is distinguished as such by being the location for the cathedra or bishop's seat. In the strictest sense, only those Christian denominations with an episcopal hierarchy possess cathedrals. However, notable churches that were formerly part of an episcopal denomination are still often informally called cathedrals.
