A saint is a person who is recognized as having an exceptional degree of holiness, or likeness to God. While the English term "saint" originated in Christianity, historians of religion now use the appellation "in a more general way to refer to the state of special holiness that many religions attribute to certain people," with the Jewish Tzadik, the Islamic Mu'min, the Hindu rishi or Sikh guru, and the Buddhist arhat or bodhisattva also being referred to as "saints". Depending on the religion, saints are recognized either by official ecclesiastical declaration/denomination or by popular acclamation (see folk saints).

Saint is the designation of a holy person.
