An Extropian is defined as one who seeks to overcome human limits, live indefinitely long, become more intelligent, and more self-creating. An Extropian is a transhumanist who affirms the values and attitudes codified and expressed in The Extropian Principles. The term was derived from the term "extropy" by Max More in 1988.

Extropians tend toward extreme optimism and self-creation. A number of them have re-named themselves (Max More).
