While the exact origin of the name Fia is uncertain, it is likely that it was derived from the Old Norse word "fríðr", meaning "beautiful" or "fair". This word is related to the Old English word "frið", which also meant "beautiful" or "fair". The name Fia may have been used as a pet form or diminutive of the longer name Fríða.
