Nikola Zadranin OFM (Latin: Nicolaus de Iadera) was a prelate of the Catholic Church who served as the bishop of Duvno from 1460.
Nikola, a Franciscan born in Zadar,[1][2] was appointed the bishop of Duvno on 2 January 1460, as it is evident from the consistorial minutes from that period.
[1][3] The circumstances of his appointment were complicated, as the territory of the diocese was a domain of Stjepan Vukčić Kosača, a nobleman who was a member of and the protector of the Bosnian Church, in conflict with the Catholic King Thomas.
On 3 April 1464, the Gemona city council accepted him as their bishop; however, it remains unknown whether the appointment was confirmed by the Pope or whether he was relegated to his episcopal duties in Duvno.
[2] Dominik Mandić wrote that the Holy See probably didn't allow the transfer and forced him to either to return to Duvno or the nearby Dalmatian town from where he could administer the diocese.
