List of private revelations approved by the Catholic Church

Private revelations approved by the Catholic Church are private revelations which the Catholic Church has judged to be in all probability (not infallibly or with absolute certainty) from God (constat de supernaturalitate), and has legalized to be published and authorized devotion to them. Shrines and feast days, when authorized by the church, are typical signs of approval since they are part of devotion to private revelation.
