维达，（Vidar，或做 Víðarr 或 Viðarr ）他是奥丁（Odin）和女巨人格莉德（Grid）所生的孩子。他是不灭的自然力之拟人化，或称「森林之神」或「原始森林之神」。他注定在诸神的黄昏之后，和他的兄弟瓦利（Vali）成为新世界的神。

他住在阿斯嘉特一片广大的森林中，他的居所叫兰德维迪（Land-vidi），意即「广土」或维迪（Vidi），意即「宽广」。他的另一个称呼是「沉默之神」，他从诺伦三女神（Norns）处得知自己命运的预言后，就待在森林深处，不发一语。

他的形象是高大，穿甲胄，带着一把阔剑，穿着一只靴子。有些人认为这靴子是铁做的，由于他的母亲格莉德知道他永将与火相争，所以为他做铁靴子以防火。另一个说法是他的靴子为皮革做的，甚至是由皮革匠们丢弃的废皮拼凑而成的。在诸神的黄昏时，芬里尔击败奥丁并将其吞下肚，维达赶上前，一脚踩住芬里尔的下额，两手抓住狼的上颚，最后把芬里尔撕为两半，报了父仇。所以也有人说他是「复仇之神」。

In Norse mythology, Víðarr (Old Norse, possibly "wide ruler", sometimes anglicized as Vidar, Vithar, Vidarr, and Vitharr) is a god among the Æsir associated with vengeance. Víðarr is described as the son of Odin and the jötunn Gríðr, and is foretold to avenge his father's death by killing the wolf Fenrir at Ragnarök, a conflict which he is described as surviving. Víðarr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, written in the 13th century by Snorri Sturluson, and is interpreted as depicted with Fenrir on the Gosforth Cross. A number of theories surround the figure, including theories around potential ritual silence and a Proto-Indo-European basis.
