The Fátima prayers are a collection of seven Catholic prayers associated with the 1917 Marian apparitions at Fátima, Portugal. Of the seven prayers, reportedly, the first two were taught to the three child visionaries by the Angel of Peace, the next three were taught to the children by Our Lady of Fátima herself during the course of the apparitions, and the final two were taught to Lúcia de Jesus Rosa dos Santos, the eldest and last survivor of the three, in 1931 by Jesus Christ when she was already a nun. Of the seven prayers, the rosary decade prayer is the best-known and the most widely recited. For each prayer below, an English translation is given alongside the Portuguese original.

Prayer in the Catholic Church is "the raising of one's mind and heart to God or the requesting of good things from God." It is an act of the moral virtue of religion, which Catholic theologians identify as a part of the cardinal virtue of justice.
