盖萨里克（Geiseric，389年－477年1月25日），其名意为“矛之王”，汪达尔人和阿兰人领袖（428年-477年在位），北非的征服者。

盖萨里克据推测于389年出生于巴拉顿湖一带，为阿斯丁汪达尔领袖戈德吉赛尔（Godigisel）的私生子。406年，戈德吉赛尔战死，盖萨里克之兄贡德里克成为阿斯丁汪达尔人的领袖，率领阿斯丁汪达尔人渡过莱茵河，进入罗马帝国属下的高卢。不久，贡德里克又率部众越过比利牛斯山脉，进入西班牙。由于受到苏维汇人的压迫，贡德里克南退到今日安达卢西亚一带，收服了锡林汪达尔和阿兰人。

Genseric or more often Gaiseric or sometimes Geiseric (c. 389 – January 25, 477), was King of the Vandals and Alans (428–477) who established the Vandal Kingdom was one of the key players in the troubles of the Western Roman Empire in the 5th century. During his nearly 50 years of rule, he raised a relatively insignificant Germanic tribe to the status of a major Mediterranean power — which, after he died, entered a swift decline and eventual collapse.
