Augustin Kažotić (Italian: Agostino Casotti, Hungarian: Kazotics Ágoston; 1260 – 3 August 1323) was a Croatian prelate of the Catholic Church and professed member from the Order of Preachers who served as the Bishop of Lucera from 1322 until his death.

[2][3] His reputation for personal holiness remained noted long after his death; this resulted in Pope Innocent XII confirming Kažotić's beatification in 1700.

The historian Baltazar Krčelić suggests that while the Zagreb Cathedral was being built in 1312 there was a drought and a source of water was dug out at the present Ban Jelačić Square at Kažotić's request.

Kažotić represented his nation's dioceses at the Council of Vienne from 1311 to 1312 which Pope Clement V had convoked in order to debate the situation regarding the Knights Templar.

[5] In 1318 he travelled to Avignon to seek assistance from Pope John XXII in regard to ongoing conflicts with King Charles Robert.

[1] In 1322 the pope assigned him (through a papal bull) to the restored Lucera diocese which was home to thousands of Muslim Saracens who served as Emperor Friedrich II's elite troops.
