Fallen angels are angels who were expelled from Heaven. The literal term "fallen angel" does not appear in any Abrahamic religious texts, but is used to describe angels cast out of heaven or angels who sinned. Such angels often tempt humans to sin.

In Abrahamic religious traditions and some sects of other belief-systems like Hinduism and Buddhism, an angel is a heavenly supernatural or spiritual being. In monotheistic belief-systems, such beings are under service of the supreme deity.
