Conchobair

Conchobair is a masculine given name of Irish origin. It represents the Gaelic form of the Old Irish name Conchobor (also rendered Conchobhar or Conchubhar) and is the basis for the surname Ua Conchobair (O'Conor). The name is associated with the royal lineage of Connacht, particularly the Uí Conchobair dynasty, and has been borne by numerous medieval rulers in western Ireland. Spelling variants in Irish include Conchobair, Conchobhar, and Conchubhar; English-language forms include Conor and Connor.

Historically, Conchobair was common among Gaelic nobility. One of the best-known bearers is Ruaidrí Ua Conchobair (Rory O'Conor), who was King of Connacht and the last High King of Ireland before the Norman invasion. The name thus has strong associations with Gaelic kingship and the dynastic politics of medieval western Ireland.

In contemporary Ireland, Conchobair appears mainly in the Gaelic spelling and is used less frequently as a given name; more common are the Anglicized forms Conor and Connor. The form Ua Conchobair remains a prominent surname, especially in Connacht.
