古尔维格（Gullveig）是一位拥有强大魔力的女神，被归属于华纳神族。

据说她就是阿萨神族和华纳神族征战的导火线。身为华纳神族的古尔维格来到阿斯嘉特，据说是来讨论两方神祇哪边比较伟大，更值得人们膜拜。另一说是说古尔维格夸耀她的魔力，出言不逊引起阿萨诸神的不满。于是奥丁掷矛以示宣战。

但是古尔维格的力量太强了，阿萨神族用茅和火想要杀死她达三次之多，但每次古尔维格都能复活。

古尔维格就只有在这场战争中登场，有一说法认为古尔维格也许是弗蕾亚（Freya）的另一个名字，因为弗蕾亚也是华纳神族中，一位拥有强大魔力的女神。

In Norse mythology, Gullveig is a being who was speared by the Æsir, burnt three times, and yet thrice reborn. Upon her third rebirth, Gullveig's name becomes Heiðr and she is described as a knowledgeable and skillful völva. Gullveig/Heiðr is solely attested in the Poetic Edda, compiled in the 13th century from earlier traditional material. Scholars have variously proposed that Gullveig/Heiðr is the same figure as the goddess Freyja, that Gullveig's death may have been connected to corruption by way of gold among the Æsir, and/or that Gullveig's treatment by the Æsir may have led to the Æsir-Vanir War.
