Pendragon, or King Arthur Pendragon, is a Tabletop role-playing game (RPG) in which players take the role of knights performing chivalric deeds in the tradition of Arthurian legend. It was originally written by Greg Stafford and published by Chaosium, then was acquired by Green Knight Publishing, who in turn passed on the rights to White Wolf Publishing in 2004. White Wolf sold the game to Stewart Wieck in 2009. Wieck formed Nocturnal Media, who updated and reissued the 5th edition originally published by White Wolf. In 2018, it returned to Chaosium.

After it was published in 1985, Pendragon won several industry awards, and reviewers highly recommended it; in following years, it was included in several "Best of" industry lists.
