Macguire is Irish in Origin.

Macguire is an Irish surname–turned–given name rooted in the Gaelic Mag Uidhir. Mag is the form of Mac (“son”) used before vowels, while Uidhir is the genitive of Odhar, a byname meaning “dun-colored, tawny, sallow.” The full sense is “son/descendant of Odhar.” The name is closely associated with the powerful Mag Uidhir (Maguire) dynasty, medieval lords of Fermanagh in Ulster, whose influence was recorded in Gaelic annals and carried into later Anglo-Irish records.

As a first name, Macguire is a contemporary choice that emerged within the wider Irish-diaspora habit of using surnames as given names, especially in the United States, Canada, and Australia. Spelling varies widely: Maguire, McGuire, MacGuire, and McGwire are common, with Gaelic Mac Uidhir/Mag Uidhir seen in historical and literary contexts. Nicknames include Mac or Mack. Typical English pronunciation is muh-GWY-er.
