Raimbaut of Orange (c. 1147 – 1173) or, in his native Old Occitan, Raimbaut d'Aurenga, was the lord of Orange and Aumelas. His properties included the towns of Frontignan and Mireval. He was the only son of William of Aumelas and of Tiburge, daughter of Raimbaut, count of Orange. After the early death of Raimbaut's father, his guardians were his uncle William VII of Montpellier and his elder sister Tibors.He was a major troubadour, having contributed to the creation of trobar ric, or articulate style, in troubadour poetry. About forty of his works survive, displaying a gusto for rare rhymes and intricate poetic form.His death in 1173 is mourned in a planh (lament) by Giraut de Bornelh, and also in the only surviving poem of the trobairitz Azalais de Porcairagues, who was the lover of Raimbaut's cousin Gui Guerrejat. It seems possible that Azalais's poem was composed in an earlier form while Raimbaut was still alive, because in his poem A mon vers dirai chanso he appears to contribute to the poetical debate begun by Guilhem de Saint-Leidier and taken up by Azalais as to whether a lady is dishonoured by taking a lover who is richer than herself (later there is a partimen on the topic between Dalfi d'Alvernha and Perdigon, and then a tensó between Giraut de Bornelh and king Alfonso II of Aragon). Aimo Sakari argues that Azalais is the mysterious joglar ("jongleur") addressed in several poems by Raimbaut.
