Veneration, or veneration of saints, is the act of honoring a saint, a person who has been identified as having a high degree of sanctity or holiness. Angels are shown similar veneration in many religions. Veneration of saints is practiced, formally or informally, by adherents of some branches of all major religions, including Christianity, Judaism, Hinduism, Islam, Buddhism and Jainism.

In Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term saint depends on the context and denomination. In Catholic, Eastern Orthodox, Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and consequently a public cult of veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval.
