Nikola Đuran (30 June 1792 – 16 August 1862) was a Croatian priest of the Catholic Church who served as a capitular vicar of the Diocese of Trebinje-Mrkan, residing in Dubrovnik from 1838 to 1839.
After the death of the previous capitular vicar of Trebinje-Mrkan, Dominik Sokolović, the Dubrovnik chapter appointed Đuran as his successor on 7 October 1837.
[1] Though the appointment of Đuran was uncanonical, the Austrian government put pressure on Pope Gregory XVI to approve the decision of the Dubrovnik chapter.
[2] The clergy of the Diocese of Trebinje-Mrkan opposed such an appointment and instead chose their fellow Vidoje Maslać as an interim capitular vicar.
Đuran's vicariate didn't last for long, as the Pope gave the administration over the Diocese of Trebinje-Mrkan to the bishop of Dubrovnik on 30 September 1939.
