Gelimer (original form possibly Geilamir, 480–553), King of the Vandals and Alans (530–534), was the last Germanic ruler of the North African Kingdom of the Vandals. He became ruler on 15 June 530 after deposing his first cousin twice removed, Hilderic, who had angered the Vandal nobility by converting to Chalcedonian Christianity, as most of the Vandals at this time were fiercely devoted to Arian Christianity.
