Juan Manuel Martín del Campo (14 December 1917 – 13 August 1996) was a Mexican Roman Catholic priest and exorcist.

[1] He was a student and friend of the bishop Saint Rafael Guízar Valencia and studied for the priesthood in secret during the Cristero War that plagued Mexico during the thirties.

[2] Valencia's successor - Manuel Pío López - appointed him as an acolyte (one who prepares liturgical celebrations) on 16 July 1939.

[3] He was ordained as a priest on 21 December 1940 and became both a teacher and a spiritual director while being appointed as the prefect of theologians from 1940 to April 1947 when he was made the confessor to the Sisters of Banderilla.

[1][3] The beatification process commenced under Pope Benedict XVI on 27 November 2008 after the Congregation for the Causes of Saints granted the "nihil obstat" ('nothing against') to the cause and titled him as a Servant of God.
