What is the name of Odin's mother in Norse mythology?

The name of Odin’s mother in Norse mythology is Bestla.

Bestla is described as a jötunn, often translated as a giantess, who became the wife of Borr. Their sons were Odin, Vili, and Vé, the three figures associated with the creation of the world from the body of the primordial being Ymir. This makes Odin’s family partly connected to the jötnar, who are not simply monsters but a broad mythological group that can be ancestors, enemies, allies, or relatives of the gods.

Bestla appears in the Prose Edda and is also remembered in skaldic poetry. In Hávamál, Odin refers to receiving magical songs from the son of Bölþorn, who is identified as Bestla’s father or grandfather depending on how the genealogy is interpreted. Her name’s meaning is uncertain, and the surviving myths provide little narrative about her.

Bestla is sometimes confused with Frigg, Odin’s wife, or Jörð, a goddess associated with Earth and the mother of Thor. Neither is Odin’s mother.
