The afterlife (also referred to as life after death or the world to come) is a purported existence in which the essential part of an individual's identity or their stream of consciousness continues to live after the death of their physical body. According to various ideas about the afterlife, the essential aspect of the individual that lives on after death may be some partial element, or the entire soul or spirit, of an individual, which carries with it and may confer personal identity or, on the contrary nirvana. Belief in an afterlife is in contrast to the belief in oblivion after death.

In some views, this continued existence takes place in a spiritual realm, and in other popular views, the individual may be reborn into this world and begin the life cycle over again, likely with no memory of what they have done in the past. In this latter view, such rebirths and deaths may take place over and over again continuously until the individual gains entry to a spiritual realm or otherworld. Major views on the afterlife derive from religion, esotericism and metaphysics.

Some belief systems, such as those in the Abrahamic tradition, hold that the dead go to a specific plane of existence after death, as determined by God, or other divine judgment, based on their actions or beliefs during life. In contrast, in systems of reincarnation, such as those in the Indian religions, the nature of the continued existence is determined directly by the actions of the individual in the ended life.
