Petar Petretić (c. 1604 – 12 October 1667) was a Croatian prelate of the Catholic Church who served as the bishop of Zagreb from 1648 to 1667.
[2] At first, he was educated in the Jesuit gymnasium in Gradec, Zagreb and then, on 20 November 1629, he went to study theology at Collegium Croaticum Viennense in Vienna.
Petretić studied there for three years but didn't receive a theology or canon law degree, though he was well acquainted with the latter due to private interest.
In 1643, Bishop Martin Bogdan, with the recommendation from King Ferdinand III, appointed Petretić the great provost of Zagreb.
[6] After Bishop Bogdan died in 1647,[7] King Ferdinand III proposed the Holy See to appoint Petretić as his successor on 4 February 1468.
