Diocese of Duvno (Latin: Dioecesis Dumnensis or Dioecesis Dalminiensis) was a Latin Roman Catholic diocese in the area of present Bosnia and Herzegovina.
It was erected in 590 as Diocese of Duvno or Delminium (the old Roman town) on territory split off from the bishopric of Makarska. Pope Gregory I mentioned this diocese in his writings from 591.
Later it was part of territory of Kingdom of Croatia. It was suppressed in 1663 and its territory merged back into its mother-diocese of Makarska.
In 1846 it was restored but demoted to a pre-diocesan jurisdiction as the Apostolic Vicariate of Herzegovina, on territories split off from the then-Apostolic Vicariate of Bosnia and the Roman Catholic Diocese of Dubrovnik.
At the restoration of regular ecclesiastical hierarchy in Bosnia and Herzegovina in 1881, Duvno was located within the boundaries of the Mostar diocese, so the bishop of Mostar adopted the secondary title of Duvno, becoming the bishop of Mostar-Duvno to maintain the memory of Duvno Diocese.
