Apatheia () in Stoic philosophy refers to a state of mind where one is free from emotional disturbance. This might be translated as equanimity or indifference. This is the root of the word apathy. Apatheia is a positive term; apathy, a purely negative one.

Whereas Aristotle had claimed that virtue was to be found in the golden mean between excess and deficiency of emotion (metriopatheia), the Stoics sought freedom from all passions (apatheia). It meant eradicating the emotional response to external events - the things we cannot control. For the Stoics, it was the optimum rational response to the world, for we cannot control things that are caused by the will of others or by Nature, we can only control our own will. This did not mean a loss of all feeling, or total disengagement from the world. The Stoic who performs correct (virtuous) judgments and actions as part of the world-order experiences contentment (eudaimonia) and good feelings (eupatheia).

The Pyrrhonian skeptics also sought the eradication of feelings when disturbance depends on belief, but allowed for only a moderation of feeling when based on sensations such as pain. The term was later adopted by Plotinus in his development of Neoplatonism, for whom apatheia was the soul's freedom from emotion achieved when it reaches its purified state.

The term passed into early Christian teaching, whereby apatheia meant freedom from unruly urges or compulsions. It is still used in this sense in Orthodox monasticism.
