奥多亚塞（Odoacer，亦作Odovacar；435年－493年）是意大利的第一个日耳曼蛮族国王（476年～493年在位）。早年参加罗马军队。475年他率众反叛篡夺者欧瑞斯特。476年被军队拥为王。这一年传统上被认为是西罗马帝国灭亡的标志。奥多亚塞宣称效忠东罗马帝国皇帝芝诺，但把意大利的统治权握在自己手里。先后征服达尔马提亚（482年），打败鲁吉人（487年～488年）。从汪达尔人手里收复了西西里岛。在东罗马帝国皇帝芝诺支持下，东哥德王国国王狄奥多里克侵入意大利（489年），夺取了半岛的大部地区。493年，奥多亚塞被狄奥多里克诱杀。

Flavius Odoacer (433–493), also known as Flavius Odovacer (Italian:Odoacre, Latin:Odoacerus German:Odoaker), was a soldier who in 476 became the first King of Italy (476–493). His reign is commonly seen as marking the end of the Western Roman Empire. Though the real power in Italy was in his hands, he represented himself as the client of Julius Nepos and, after Nepos' death in 480, of the Emperor in Constantinople. Odoacer generally used the Roman honorific patrician, granted by the Emperor Zeno, but is referred to as a king (Latin rex) in many documents and he himself used it at least once and on another occasion it was used by the consul Basilius. Odoacer introduced few important changes into the administrative system of Italy. He had the support of the Roman Senate and was able to distribute land to his followers without much opposition. Unrest among his warriors led to violence in 477–478, but no such disturbances occurred during the later period of his reign. Although Odoacer was an Arian Christian, he rarely intervened in the affairs of the orthodox and trinitarian state church of the Roman Empire.
