The Diocese of Kalmar () was a division of the Church of Sweden between 1603 and 1915, when it was merged into the diocese of Växjö in order to allow the new diocese of LuleÃÂ¥ to be formed. It was created as a subdivision to the diocese of Linköping, and was under the supervision of a superintendent. Only in 1678 was a bishop appointed, and Kalmar cathedral became an episcopal see in the term proper. Till this day, the cathedral of Kalmar retain its rank despite no longer being the seat of a bishopric.
