The name has spread through Irish migration and today appears widely in Ireland and in countries with large Irish diasporas, including the United States, Canada, the United Kingdom, and Australia. Variant spellings such as Maguire and MacGuire reflect different Gaelic roots and transliteration traditions.

In addition to its use as a family name, McGuire appears in place and institution names, often named after individuals bearing the surname. The most prominent example is McGuire Air Force Base in New Jersey, which is now part of Joint Base McGuire-Dix-Lakehurst, a major United States military installation.

Notable individuals with the surname include Al McGuire (1931–2001), an American college basketball coach and broadcaster who led Marquette University to the 1977 NCAA championship. Beyond sports, bearers of the name have contributed to politics, arts, academia, and business across various countries, reflecting the surname’s wide distribution.
