From Irish Gaelic 'Condún,' an anglicized Norman-Irish surname meaning 'dark-haired warrior.'
Condon comes from Irish Gaelic Condún, an anglicized Norman-Irish surname meaning 'dark-haired warrior.' Like many surnames that became given names, it preserves a fragment of social history in compressed form, carrying echoes of medieval identity, family lineage, and the migration of Norman names into Irish usage.
Its meaning is vivid and martial, which gives the name a distinctly old-world strength. As a given name, Condon feels firm and surname-like, with a practical, unadorned sound. It has the sort of weight that suggests ancestry and permanence rather than fashion.
Because it is rare as a first name, it can seem especially deliberate, as though chosen for its steady, no-nonsense character. Condon is not showy, but it has presence; its appeal lies in the way it sounds established, masculine, and quietly historic.
