Diocese of Knin

The Catholic diocese of Tinin (Italian), or diocese of Knin (Croatian placename) was in Dalmatia (now Croatia). It existed from the eleventh century to 1622, when the Ottoman conquest of Knin drove out the bishops.

It then effectively became a titular see, though this status is not entirely clear. It may notionally have continued, suffragan to the archdiocese of Kalocsa-Bacs.
