厄尔曼纳里克（哥特语：Aírmanareiks；拉丁语：Ermanaricus；古英语：Eormenric；古诺尔斯语：Jǫrmunrekr；？－376年）是哥特族格鲁森尼人的一位国王。其在位年代大约在4世纪中后叶。

厄尔曼纳里克在位期间，格鲁森尼人的统治疆域大概在艾乌姆地区（西徐亚地区的一部分）。根据罗马历史学家阿米阿努斯·马尔切利努斯的记载，厄尔曼纳里克是一位“极为好战的君王”，统治着极为广阔而肥沃的地域。375年，格鲁森尼遭到匈人和阿兰人联军的袭击，大败，羞愧自杀。此后，维提米利斯继承王位。

Ermanaric (Gothic:Aírmanareiks; Latin:Ermanaricus; Old English:Eormanrīc [eormɑnriːtʃ]; Old Norse:Jǫrmunrekr; died 376) was a Greuthungian Gothic King who before the Hunnic invasion evidently ruled a sizable portion of Oium, the part of Scythia inhabited by the Goths at the time. He is mentioned in two Roman sources; the contemporary writings of Ammianus Marcellinus and in Getica by the 6th-century historian Jordanes. Modern historians have postulated that Ermanaric at one point ruled a realm stretching from the Baltic Sea to the Black Sea as far eastwards as the Ural Mountains.
