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.

King Charles III later signed a decree that led to Pirrotti's expulsion from the Kingdom of Naples; he rescinded the order upon increasing public pressure.

He died and was buried where he was, in Apulia; but in 1966 his remains were transferred to the Sanctuary created for him, Santuario San Pompilio Maria Pirrotti.

[5] There is a Catholic church in Montecalvo Irpino, Italy, which is located in the Archdiocese of Benevento and is dedicated to St. Pompilio Maria Pirrotti.

The proceedings for sainthood commenced in a diocesan process in Leece in 1835 and formal assent to the cause was granted not long after in which Pirrotti was accorded with the title Servant of God.

Another process opened sometime after with the same intent of collecting documentation and material for compiling a large dossier on his life and works which was later transferred to the Congregation of Rites.

On 17 November 1878 he was proclaimed to be Venerable after Pope Leo XIII recognized that the late priest had lived a model life of heroic virtue.

Following the recognition of two other miracles Pope Pius XI canonized Pirrotti as a saint of the Roman Catholic Church on 19 March 1934.
