Pompilio Maria Pirrotti (29 September 1710 – 15 July 1766), 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. In 1890 Pope Leo XIII beatified him and Pope Pius XI proclaimed him to be a saint of the Roman Catholic Church on 19 March 1934.
