The Poetic Edda (a collection of older anonymous poems) frequently uses kennings (metaphorical compound phrases) to refer to Thor. One of the most common is “Son of Fjörgyn.” In Hymiskviða (The Lay of Hymir), Thor is repeatedly identified as “Fjörgyn’s child.” The name Fjörgyn is almost certainly a poetic synonym for “Earth” or “Land,” making it linguistically and functionally identical to Jord. Some scholars suggest Fjörgyn may be an older, more mythologically resonant name for the same earth-goddess figure. Notably, Fjörgyn is also a masculine name for a separate figure in some contexts, but in reference to Thor’s mother, it is feminine.

Thor's biological mother is Jörd (also known as Jord ), a giantess who personifies the Earth.

The most direct answer to the question is Jord (Old Norse Jörð , pronounced “Yorth”), which literally means “Earth.” In the Prose Edda by Snorri Sturluson (c. 1220), the section Gylfaginning explicitly states: “Jörd, the daughter of Annar (Onar) and Nótt (Night), was the mother of Thor.” Snorri also lists her among the Ásynjur (goddesses), though she is also described as a giantess by nature. This dual classification emphasizes her chthonic (earth-based) power. She represents the raw, untamed land—a fitting mother for the god of thunder, whose hammer, Mjölnir, is intrinsically linked to storms that fertilize the soil.
