Michael (Hebrew: מִיכָאֵל‎, Micha'el or Mîkhā'ēl; Greek: Μιχαήλ, Mikhaíl; Latin: Michael or Míchaël; Arabic: ميخائيل‎, Mikha'il) is an archangel, one of the principal angels in Judeo-Christian and Islamic tradition. He is viewed as the good Angel of Death (as opposed to Samael, the evil Angel of Death), and as the field commander of the Army of God.

He is mentioned by name in the Book of Daniel and the Book of Revelation 12:7. In the book of Daniel, Michael appears as "one of the chief princes" (Daniel 10:13) who in Daniel's vision comes to the angel Gabriel's aid in his contest with the angel of Persia Dobiel, and is also described there as the advocate of Israel and "great prince who stands up for the children of your (Daniel's) people" (Daniel 10:21, 12:1).

The Talmudic tradition rendered his name as meaning "who is like El (God)?". In recent years, a popular mistake has become to translate the name as "One who is like God." It is, however, meant as a question: "Who is like the Lord?" The name was said to have been the war-cry of the angels in the battle fought in heaven against Satan and his followers.
