An ex-voto is a votive offering to a saint or a divinity, given in fulfillment of a vow (hence the Latin term, short for ex voto suscepto, "from the vow made") or in gratitude or devotion.^[1] The term is usually restricted to Christian examples.

Ex-votos are placed in a church or chapel where the worshiper seeks grace or wishes to give thanks. The destinations of pilgrimages often include shrines decorated with ex-votos.

Ex-votos can take a wide variety of forms. They are not only intended for the invocated, but also as a testimony to later visitors of the received help. As such they may include texts explaining a miracle attributed to the helper, or symbols such as a painted or modeled reproduction of a miraculously healed body part, or a directly related item such as a crutch given by a person formerly lame.
