An angel is a spiritual supernatural being found in many religions. Although the nature of angels and the tasks given to them vary from tradition to tradition, in Christianity, Judaism and Islam, they often act as messengers from God. Other roles in religious traditions include acting as warrior or guard; the concept of a "guardian angel" is popular in modern Western culture.

Angels are usually viewed as emanations of a supreme divine being, sent to do the tasks of that being. Traditions vary as to whether angels have free will or are merely extensions of the supreme being's will. While the appearance of angels also varies, many views of angels give them a human shape.
