In Norse mythology, Jörð (Old Norse , "earth" pronounced [ˈjɔrð], Icelandic Jörð, pronounced [ˈjœrð], sometimes Anglicized as Jord or Jorth; also called Jarð, [jɑrð] as in Old East Norse), is a female jötunn. She is the mother of the thunder god Thor, son of Odin, and the personification of the Earth. Fjörgyn and Hlóðyn are considered to be other names for Jörð. Some scholars refer to Jörð as a goddess. Jörð's name appears in skaldic poetry both as a poetic term for the land and in kennings for Thor.
Jörð is the common word for earth in Old Norse, as are the word's descendants in the modern Scandinavian languages; Icelandic jörð, Faroese jørð, Danish, Swedish and Norwegian jord. It is cognate to English "earth" through Old English eorðe.
In Gylfaginning, the first part of the Prose Edda, Jörð is described as one of Odin's sexual partners and the mother of Thor. She is the daughter of Annar and Nótt and half-sister of Auðr and Dagr.
