The Peripatetic school was a school of philosophy in Ancient Greece.

Its teachings derived from its founder, the Greek philosopher, Aristotle, and peripatetic is an adjective ascribed to his followers. The school originally derived its name Peripatos (Greek: Περίπατος) from the peripatoi (περίπατοι, "colonnades") of the Lyceum in Athens where the members met. A similar Greek word peripatetikos (περιπατητικός) refers to the act of walking, and as an adjective, "peripatetic" is often used to mean itinerant, wandering, meandering, or walking about. After Aristotle's death, a legend arose that he was a "peripatetic" lecturer – that he walked about as he taught – and the designation Peripatetikos came to replace the original Peripatos.
