Fjörgynn is a mysterious male figure in Norse myth, cited as Frigg’s father in the Poetic Edda. His name parallels Fjörgyn, suggesting a chthonic or forest-related deity. Little else is known, but his existence implies a dual earth-god lineage. Poets may reference Fjörgynn to underscore Frigg’s deep roots in nature and the ancestral ties binding the Æsir to the land.

Fjörgynn is the masculine counterpart to Fjörgyn and is identified in Gylfaginning as the father of Frigg. While absent from the Poetic Edda, his name appears in skaldic kennings such as "Fjörgynn’s daughter" for Frigg. The pairing of Fjörgyn (feminine, Thor’s mother) and Fjörgynn (masculine, Frigg’s father) illustrates how Old Norse uses slight name variations to denote gender and lineage. Students should recognize this as an example of how Norse myth encodes genealogy through nomenclature. Though Fjörgynn has no myths, his existence reinforces Frigg’s noble status and divine ancestry. When analyzing kennings, identifying such parental names helps unpack references to major deities and reveals the importance of familial ties in mythological structure.
