Raimbaut of Orange (c. 1147 – 1173) or, in his native Old Provençal, 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, Countess of Orange, 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.
