Ó Broin is the original Irish Gaelic form of the surname O'Byrne. Both surnames derive from the Old Irish personal name Bran 1, meaning “raven.” In Irish mythology, Bran mac Febail was a legendary mariner who journeyed to the Otherworld. The surname originally indicated descent from a person named Bran.
The name is chiefly associated with Leinster, where the Ó Broin clan held significant territories in what is now County Wicklow. The clan was part of the Uí Cheinnselaigh sept and played a notable role in medieval Irish history, resisting Norman and later English incursions. Over time, the Gaelic Ó Broin was anglicized to Byrne, O'Byrne, and other variants such as Beirne, Berne, and Byrnes.
Notable bearers of the anglicized Byrne surname include many historical and contemporary figures. For instance, Alfred “Alfie” Byrne served as Lord Mayor of Dublin and a Member of Parliament. However, because Ó Broin itself refers to the Gaelic root, it is less common as a modern surname but is preserved within genealogical records.
