Michael (Hebrew: מִיכָאֵל‎ (pronounced [ˌmixäˈʔel]), Micha'el or Mîkhā'ēl; Greek: Μιχαήλ, Mikhaḗl; Latin: Michael or Míchaël; Arabic: ميخائيل‎, Mīkhā'īl) is an archangel in Jewish, Christian, and Islamic teachings. Roman Catholics, the Eastern Orthodox, Anglicans, and Lutherans refer to him as Saint Michael the Archangel and also simply as Saint Michael. Orthodox Christians refer to him as the Taxiarch Archangel Michael or simply Archangel Michael.

In Hebrew, Michael means "who is like God" (mi-who, ke-as or like, El-deity), which is traditionally interpreted as a rhetorical question: "Who is like God?" (which expects an answer in the negative) to imply that no one is like God. In this way, Michael is reinterpreted as a symbol of humility before God.

In the Hebrew Bible Michael is mentioned three times in the Book of Daniel, once as a "great prince who stands up for the children of your people". The idea that Michael was the advocate of the Jews became so prevalent that in spite of the rabbinical prohibition against appealing to angels as intermediaries between God and his people, Michael came to occupy a certain place in the Jewish liturgy.
