Jordan of Santa Susanna

Jordan (Italian: ; died after 1154) was a Carthusian monk, created Cardinal Deacon by Pope Lucius II in December 1144 and then Cardinal Priest of Santa Susanna by Eugene III on 21 December 1145. He is often referred to as a member of the Roman family of the Orsini, but more recent research concludes that he was probably a Frenchman. He served as Camerlengo of the Holy Roman Church under Eugene III (attested 8 March 1147 until 1151) and subscribed the papal bulls between 9 January 1145 and 11 June 1154.

He participated in the papal election of 1153 and perhaps also in the papal election of 1154. The date of his death is uncertain.
