The Fatima Prayer is a prayer of the Rosary, one of the central devotional practices in the Roman Catholic form of the Christian religion. It is prayed during the Rosary on the large beads which separate the five sets of ten smaller beads, called decades, upon each of which a Hail Mary is prayed. An Our Father and Glory Be to the Father are also commonly prayed on these large beads. While not part of the original Rosary, many Roman Catholics believe it to have been requested by the Blessed Virgin Mary during her apparition at Fatima, an alleged miracle deemed "worthy of belief" by the Church.

"O my Jesus, forgive us our sins, save us from the fires of hell, lead all souls to Heaven, especially those who have most need of your mercy."

"Oh mi Jesu, dimitte nobis debita nostra, libera nos ab igne inferni, conduc in caelum omnes animas, praesertim illas quae maxime indigent misericordia tua."
