The phrase false god is a derogatory term used in Abrahamic religions to indicate cult images or deities of non-Abrahamic, Pagan religions – as well as other competing entities or objects to which particular importance is attributed.

Usage of this term is generally limited to theists, who choose to believe in some deity or more deities, but not in others.
