In theology, divine light is an aspect of divine presence perceived as light during a theophany or vision, or represented as such in allegory or metaphor.

According to divine illumination, the process of human thought needs to be aided by divine grace. It is the oldest and most influential alternative to naturalism in the theory of mind and epistemology. It was an important feature of ancient Greek philosophy, Neoplatonism, medieval philosophy, and the Illuminationist school of Islamic philosophy.
