Jörð (Old Norse: Jörð, meaning ‘Earth’) is the personification of the earth and the mother of Thor. She is attested in the Poetic Edda — Völuspá and Hárbarðsljóð both reference Thor as son of Jörð — and in the Prose Edda’s Gylfaginning. She is listed among the Ásynjur in Gylfaginning despite her nature as an earth-personification and likely jötunn lineage.

Jörð’s parentage is given in Gylfaginning as Annar (or Ónarr) and Nótt (Night), though this genealogy is primarily Snorri’s systematization. Her name is a common noun meaning ‘earth’ in Old Norse, and she functions in the mythological system as the deified earth — the literal ground of Miðgarðr — rather than as a narrative agent with her own story.
