Pompilio Maria Pirrotti, born Domenico Michele Giovan Battista, was an Italian Roman Catholic priest and a professed member of the Piarists. He operated across the Kingdom of Naples as a teacher and as a preacher and he received widespread criticism from detractors that led to his immediate expulsion from the kingdom at the behest of the King. He was later readmitted into the kingdom after public pressure.
