(Ἱλδέριχος), king of the Vandals, son of Hunncric, and grandson of Hilderic, successor of Trasamund, reigned A. D. 523-530. He was of a gentle disposition, and by his lenity to the African Catholics won the favour of Justinian, though there is no reason for believing the assertion of Nicephorus (17.11) that he was not an Arian. He was deposed, and finally murdered, by Gelimer. There is a scarce silver coin of this prince, bearing his head on the obverse, with D. N. HILDERIX REX, and the figure of a female on the reverse, with FELIX KART. (Procop. Bell. Vand. 1.9, 17; Eckhel, vol. iv. p. 138.)
