Cathair is Irish in Origin.

Cathair is an early Irish Gaelic masculine name, pronounced KAH-her. Most etymologies derive it from Old Irish cath “battle” plus a masculine suffix -air, yielding the sense “warrior; battle-man.” The name is homonymous with the noun cathair “fort, city,” and sometimes re-spelled Cathaoir in Modern Irish; these similar-looking common nouns (cathair ‘city’ and cathaoir ‘chair’) are etymologically distinct from the personal name.

Attested in early medieval genealogies and sagas, it is best known through Cathair Mór, the legendary 2nd‑century High King of Leinster, and it recurs in the annals through the Middle Ages. Variants include the Anglicized Cahir and the modern Irish form Cathaoir; place‑name spellings such as Cahir/Caher preserve the same root. While rare as a given name today, it persists in Ireland as a heritage choice and echoes in toponyms like Cahir (Tipperary), reinforcing associations of strength, protection, and martial prowess.
