Marijan Lišnjić OFM (14 May 1609 – 7 March 1686) was a Croatian and Bosnian-Herzegovinian prelate of the Catholic Church who served as the bishop of Makarska from 1664 and apostolic administrator of Duvno from 1667 to his death in 1686.
Lišnjić was the first to introduce secular clergy to Bosnia Eyalet after it fell to the Ottomans in the 15th century, the region where the pastoral care was given to the Franciscans.
Lišnjić was born either in Sovići or Gorica near Grude in Herzegovina, at the time part of the Ottoman Empire.
However, due to the opposition from the Austrian Emperor and the Bosnian Franciscan clergy, he wasn't appointed to the office.
[2][6] Part of the population of the Diocese of Makarska fled to the neighbouring isles of Brač and Hvar, while those that remained were maltreated by the Uskoks.
[6] Lišnjić's work was also burdened because he needed to pay out the local pasha and various Ottoman officials to act freely.
[2] In 1667, Lišnjić visited the village of Raška Gora to be surprised that the population there didn't know what a bishop was.
The situation in the parish of Roško Polje was even worse, where there were five Catholic and seven Muslim families, while the church of St. John the Baptists was in ruins.
[7] The believers in the parish of Mostar, which belonged to the Diocese of Makarska, weren't allowed to have masses and were persecuted by the Ottomans.
Lišnjić intended to give Rakitno, Tribistovo and Roško Polje to Radunović for pastoral care, but failed.
[14] While on his way back to Dalmatia, on 5 April 1673, Lišnjić was given the administration over the Diocese of Skradin, which was vacant since its last bishop Pavao Posilović died in 1656/57.
However, Lišnjić continued to stand for the faithful, entering into a dispute with the bishop of Bosnia over the parishes controlled by the Rama friary.
On 21 February 1684, he asked the Congregation to ban the bishop of Bosnia Nikola Ogramić from coming to the territory of the Sanjak of Klis where these parishes were located.
