An aureola or aureole (diminutive of Latin aurea, "golden") is the radiance of luminous cloud which, in paintings of sacred personages, surrounds the whole figure.

In Romance languages, the noun Aureola is usually more related to the disc of light surrounding the head of sacred figures, which in English is called halo or nimbus. In Indian religions, the back or head halo is called prabhāmaṇḍala or prabhavali.
