'''Tighearnán Mór Ua Ruairc''' (older spelling: '''Tigernán Mór Ua Ruairc'''), anglicised as '''Tiernan O'Rourke''' ([[floruit|fl.]] [[1124 in Ireland|1124]]–[[1172 in Ireland|1172]]) ruled the [[kingdom of Breifne]] as the 19th king in its Ua Ruairc (later O'Rourke) dynasty (964–1605 CE), a branch of the [[Uí Briúin]]. He was a descendant of Uí Riagain,{{Clarify|reason=The O'Rourkes were members of an entirely different dynasty from the Uí Riagáin. Is this to say that Tighearnán had a non-patrilineal descent from that family?|date=March 2019}} and one of the provincial kings in Ireland in the twelfth century, constantly expanding his kingdom through shifting alliances, of which the most long-standing was with [[Toirdelbach Ua Conchobair]] King of [[Connacht]] and [[High King of Ireland]], and subsequently his son and successor [[Ruaidhri Ua Conchobair|Ruaidhrí Ua Conchobair]]. He is known for his role in the expulsion of [[Diarmait Mac Murchada]], King of [[Leinster]], from Ireland in 1166. Mac Murchada's subsequent recruitment of [[Marcher Lords]] to assist him in the recovery of his Kingdom of Leinster ultimately led to the [[Norman invasion of Ireland]].
