Etiona is a Celtic goddess worshipped in Gaul; she is known only from inscriptions in Etrechy, France, where she was accompanied by her fellow deities Carantana, Isosa, Gnatus, and Hidua.

Myth
Unknown.

Cult
Etiona received votive and dedicatory offerings from her worshippers; otherwise little is known of the specifics of her cult.

Etymology
The origin of Etiona’s name is unclear. I have seen it suggested that it derives from the Proto-Celtic *ett(n)jo or “kernel” and that this indicates that she is a goddess of wisdom (i.e. “kernel of knowledge”) but I wonder if it could equally well indicate a connection to agriculture or food stores.
