Anzelmo Katić (born 23 September 1715 – 24 January 1792) was a Croatian Franciscan and prelate of the Catholic Church from Dubrovnik who served as the bishop of Trebinje-Mrkan.
Katić was born in Jasenica, Konavle, part of the parish of Stračva, to father Miho and mother Stana née Pavić-Kolić (Pavlikoli).
Katić went to study philosophy and theology in Melfi in present-day Italy, where he was ordained a priest on 7 February 1740 by the Archbishop of Nazareth Nicola Iorio, at the time seated in Barletta.
[3] The official seat of the diocese, the uninhabited island of Mrkan, belonged to the Republic of Ragusa,[4] while the bishops lived within Dubrovnik itself.
After being released from prison, Katić went on foot back to the Republic of Ragusa on 23 December 1763 and tried to get the Ragusan diplomacy to help him lobby for his free stay in the diocese with the Ottoman government.
However, the Ragusan government was uninterested in such a deal, and only in 1777 did it gain a ferman, which allowed the bishop free activity on the diocese territory.
