The Bishop of Mostar-Duvno is the head of the Roman Catholic Diocese of Mostar-Duvno, located in Bosnia and Herzegovina. It is responsible for looking after the diocese's spiritual and administrative needs. The Diocese of Mostar-Duvno is part of the ecclesiastical province of Vrhbosna and thus is a suffragan of that archdiocese.^[1] Since 1890, the bishops of Mostar-Duvno have also served as apostolic administrators of the Diocese of Trebinje-Mrkan.^[2] The current bishop is Petar Palić, who serves since 2020 and is the 6th ordinary.

During the Ottoman rule, the Holy See established the Apostolic Vicariate of Herzegovina in 1846.^[3] With the Austro-Hungarian occupation of Bosnia and Herzegovina in 1878, Pope Leo XIII restored the regular church hierarchy there with the papal bull Ex hac augusta on 5 July 1881, thus establishing the Diocese of Mostar-Duvno.^[4]

Six men have been bishop of Mostar-Duvno; the first two bishops were Franciscan friars – Paškal Buconjić, who served 29 years, from 1881 to 1910,^[5] and was also the last apostolic vicar of Herzegovina,^[6] and Alojzije Mišić, who served for 30 years, from 1912 to 1942.^[7] The first secular priest appointed bishop was Petar Čule who had the longest tenure of 38 years, serving from 1942 to 1980.^[8] His successor Pavao Žanić reigned for 13 years, from 1980 to 1993,^[9] marking the shortest episcopacy. His successor Ratko Perić held the episcopal office for 27 years, from 1993 to 2020, when he was succeeded by the incumbent bishop Petar Palić.^[10]
