Icauna is a Celtic goddess worshipped in Gaul; she may have been a river goddess, associated with the Yonne.
Icauna received votive and dedicatory offerings from her worshippers; otherwise little is known of the specifics of her cult.
Icauna’s name is linked to the Yonne River in France. It may have been derived from the Proto-Celtic *iska or “water.”
Icauna is known from a single worship site in Auxerre, France.
