Zeno, a Greek, was the Bishop of Mérida in the late fifth century. Though he had traditionally been ascribed the see of Seville, it has now been shown that he was in fact metropolitan of Lusitania and thus bishop of the provincial capital of Mérida. The dates of his episcopate are unknown besides the date of 483 and the fact of a surviving letter from Pope Felix III (483–492). According to an inscription dated to 483 and surviving in a ninth-century copy, Zeno and , a Gothic official, repaired the walls of Mérida and the bridge over the Guadiana there.
