In parapsychology, spirituality and New Age belief, an aura is a subtle field of luminous multicolored radiation surrounding a person or object as a cocoon or halo. An aura may be held to represent or be composed of soul vibrations or chakras, and may reflect the moods or thoughts of the person it surrounds.

Skeptics such as Robert Todd Carroll say that although there is no scientific evidence for supernatural perception of auras, auras may be seen for explainable reasons such as migraines or synaesthesia.
