Ruaidrí mac Tairrdelbach Ua Conchobair (Modern Irish: Ruairí Ó Conchúir; anglicised as Rory O'Conor) (c. 1116 – 2 December 1198) was King of Connacht from 1156 to 1186, and High King of Ireland from 1166 to 1198. He was the last High King of Ireland before the Anglo-Norman invasion.
Ruaidrí was one of over twenty sons of King Tairrdelbach Ua Conchobair (1088–1156). He and his sister Mór were Tairrdelbach's only children from his third wife, Cailech Dé Ní Eidin of Aidhne.
