亚尔维斯，Alvíss。是北欧神话中的一名侏儒，名字的意思是「全知」（All-Wise）。他出现在《诗体埃达》（Poetic Edda）中。

故事提到亚尔维斯曾经向索尔（Thor）提请求，希望和其女儿斯露德（Thrud）结婚，虽然亚尔维斯是个很有能力的侏儒，但索尔不愿将女儿嫁给他，所以故意以测验智商为理由，问了亚尔维斯一整个晚上的问题，当太阳出现时，亚尔维斯就因为照到太阳光而化为石头。

Alvíss ("All-Wise") was a dwarf in Norse mythology.

Thor's daughter, Þrúðr, was promised in marriage to Alvíss. Thor was unhappy with the match however, so he devised a plan. He told Alvíss that, because of his small height, he had to prove his wisdom. Alvíss agreed, but Thor made his tests last until dawn, when Alviss, because he was a dwarf, was turned to stone on being exposed to the sunlight.
