Parkour is a physical discipline inspired by human movement, focusing on uninterrupted, efficient forward motion over, under, around and through obstacles (both man-made and natural) in one's environment. Such movement may come in the form of running, jumping, climbing and other more complex techniques. The goal of parkour is to adapt one's movement to any given obstacle.

According to founder David Belle, the spirit of parkour is guided in part by the notions of "escape" and "reach", that is, the idea of using physical agility and quick thinking to get out of difficult situations, and to be able to go anywhere that one desires.
