Coursing by humans is the pursuit of game or other animals by dogs—chiefly greyhounds and other sighthounds—catching their prey by speed, running by sight, but not by scent. Coursing was a common hunting technique, practised by the nobility, the landed and wealthy, as well as by commoners with sighthounds and lurchers. In its oldest recorded form in the Western world, as described by Arrian, it was a sport practised by all levels of society, which remained the case until Carolingian period forest law appropriated hunting grounds, or commons, for the king, the nobility, and other land owners. It then became a formalised competition, specifically on hare in Britain, practised under rules, the Laws of the Leash.

As a zoological term, it refers to predation by running down prey over long distances, as opposed to stalking, in which a stealthy approach is followed by a short burst of sprinting.
