Frigg (Old Norse: Frigg) is the wife of Odin and the highest-ranking of the Ásynjur (female Æsir deities), attested across multiple primary sources including the Poetic and Prose Eddas and the Germania of Tacitus. Her name is cognate with Old High German Frîja and Proto-Germanic *Frijjō, etymologically related to the word for ‘beloved.’ Friday (Old Norse Frjádagr, Old English Frīgedæg) is named for her. She dwells in her hall Fensalir (Fen-Halls), as named in Völuspá, and is the mother of Baldr.

Frigg’s most prominent mythological role is in the narrative of Baldr’s death, preserved in Gylfaginning. Foreknowing that Baldr is in danger, Frigg extracts oaths from all things in creation not to harm him — all things except the mistletoe, which she considers too young. This omission is exploited by Loki, who fashions a mistletoe dart that the blind Höðr unknowingly throws, killing Baldr.

Frigg is explicitly described in Gylfaginning as knowing the fates of all beings, though she does not speak of what she knows. The Merseburg Charms (Old High German, tenth century) — one of the very few preserved pre-Christian German ritual texts — invoke a figure named Friia alongside Volla in a healing context, providing important non-Scandinavian attestation for the goddess.
