Praxis is the process by which a theory, lesson, or skill is enacted, practiced, embodied, or realised. "Praxis" may also refer to the act of engaging, applying, exercising, realizing, or practicing ideas. This has been a recurrent topic in the field of philosophy, discussed in the writings of Plato, Aristotle, St. Augustine, Immanuel Kant, Søren Kierkegaard, Karl Marx, Martin Heidegger, Hannah Arendt, Paulo Freire, Ludwig von Mises, and many others. It has meaning in the political, educational, and spiritual realms.

In Ancient Greek the word praxis (πρᾶξις) referred to activity engaged in by free men. Aristotle held that there were three basic activities of man: theoria, poiesis and praxis. There corresponded to these kinds of activity three types of knowledge: theoretical, to which the end goal was truth; poietical, to which the end goal was production; and practical, to which the end goal was action. Aristotle further divided practical knowledge into ethics, economics and politics. He also distinguished between eupraxia (εὐπραξία, "good praxis")[ and dyspraxia (δυσπραξία, "bad praxis, misfortune").[
