Pacificus of San Severino (1 March 1653 – 24 September 1721), born Carlo Antonio Divini, was an Italian Roman Catholic priest known for being a miracle-worker.

He was raised by his maternal uncle Luzizio Bruni, archdeacon of the Cathedral of San Severino, a good and cultured man, but far too strict to care for a small child.

Pacificus was ordained to the priesthood on 4 June 1678 and served as professor of philosophy for the next six years for the newer members of the order at Fossombrone.

Subject all his life long to intense bodily pains, "he sought for comfort and relief in God alone, and was by him favoured with marvellous supernatural graces and with the gift of working miracles".

From 1692 to 1693, he held the post of Guardian in the convent of Santa Maria delle Grazie in San Severino, where he later died on 24 September 1721.

The following year, Pacificus' relics were covered by a wax figure, placed in a glass coffin and moved to a chapel built in his honor.
