Abandinus is a Celtic god worshipped in Britain. He may have been a river god although there is only etymological evidence to suggest this. He may also have a connection to a bird or birds, given that he received a bronze feather as a votive offering.
Abandinus received votive and dedicatory offerings from his worshippers; otherwise little is known of the specifics of his cult.
The origin of Abandinus’ name is uncertain but may derive from the Proto-Celtic *abonan or “river.”
Abandinus is known from a single inscription found at Godmanchester, England.
