Mcguire is Irish in Origin.

McGuire is an Irish surname adapted as a modern given name. It derives from the Gaelic Mag Uidhir, with mag/mac meaning “son (of)” and Odhar meaning “dun-colored” or “sallow,” hence “descendant of the dun‑haired one.” The Maguires were influential medieval chiefs of Fermanagh in Ulster, and the surname spread widely through Irish diaspora migrations. Anglicized spellings settled into Maguire and McGuire, the latter especially common in North America.

As a first name, McGuire fits the contemporary surname‑as‑given‑name trend, appearing in English‑speaking countries from the late 20th century onward, usually for boys but increasingly unisex. Variant spellings include Maguire, MacGuire, and McGwire; related surnames share the same root. The standard pronunciation is muh-GWY-er (rhymes with “wire”). Parents may be drawn to its crisp, Irish heritage and the built‑in nickname Mac or even Guy, while its meaning evokes earthy color and clan lineage rather than a specific virtue.
