In Norse mythology, Hoddmímis holt (Old Norse "Hoard-Mímir's"holt) is a location where Líf and Lífþrasir are foretold to survive the long winters of Fimbulvetr. Hoddmímis holt is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. Scholarly theories have been proposed about the location and its potential connection to the world tree Yggdrasil and folktales recorded from Germanic Europe.
In the poem Vafþrúðnismál, collected in the Poetic Edda, the god Odin poses a question to the jötunn Vafþrúðnir, asking who among mankind will survive when the winter Fimbulvetr occurs. Vafþrúðnir responds that they will be Líf and Lífþrasir, that the two will have hidden in the wood of Hoddmímis holt, they will consume the morning dew as food, and "from them generations will spring."
In chapter 53 of the Prose Edda book Gylfaginning, High tells Gangleri (king Gylfi in disguise) that two people, Líf and Lífþrasir, will lie hid in Hoddmímis holt during "Surt's fire," and that "from these people there will be descended such a great progeny that the world will be inhabited." The above-mentioned stanza of Vafþrúðnismál is then quoted.
Connections have been proposed between the forest and Mímameiðr ("Mímir's tree"), generally thought to refer to the world tree Yggdrasil, and Mímisbrunnr. Based on this association, all three have been theorized as having been considered within the same proximity.
