Dubhthach is Irish, Irish (Gaelic) in Origin.

Dubhthach is an Old Irish masculine given name built from dubh “dark, black” and the adjectival suffix ‑thach “possessing/characterized by,” yielding the sense “the dark(-haired) one” or “dark‑complexioned.” It is well documented in early Ireland: most famously Dubthach maccu Lugair, a 5th‑century poet and Brehon jurist who, in tradition, counseled Saint Patrick and helped reconcile native law with Christian practice. The name recurs in medieval annals and martyrologies, borne by bishops, abbots, and learned men, but fell from everyday use after the Middle Ages.

Orthography varies: Old Irish Dubthach; later standardized as Dubhthach; the genitive Dubhthaigh underlies the hereditary surname Ó Dubhthaigh, Anglicized Duffy. Related bynames such as Duff (from dubh) appear in Scotland and Ireland, though as separate formations. Today Dubhthach is rare as a given name, mainly revived in Gaelic and antiquarian contexts, while retaining its etymological sense of “the dark one.”
