Michael ( /ˈmaɪkəl/) is a given name that comes from the Hebrew: מִיכָאֵל / מיכאל‎ (Mikha'el), derived from the Hebrew question מי כמו אלוהים? (Hebrew pronunciation: [mi kəmo ʔelohim]) meaning "Who is like God?" In English, it is sometimes shortened to Mike, Mikey, or, especially in Ireland, Mick. In Russian language, it is Mikhail and Mykhailo in Ukrainian.

Female forms of Michael include Michèle, Michelle, Michaela, Mechelle, Micheline, and Michaelle, although Michael is occasionally seen as a female name, with women named Michael including actresses Michael Learned and Michael Michele. Another form is Mychal, which can either be a male or female name. Surnames that come from Michael include Carmichael, Dimichele, MacMichael, McMichael, Micallef, Michaelson, Mikhaylov, Mykhaylenko, Michaels and Mitchell.

The name first appears in the Bible, Numbers 13:13, where Sethur the son of Michael is one of twelve spies sent into the Land of Canaan. The Archangel Michael, referred to later in the Bible (Daniel 12:1), is considered a saint by the Roman Catholic Church and Eastern Orthodox Church. 29 September is the feast day of the three archangels, Michael, Gabriel and Raphael.
