Pendragon is a role-playing game 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, Inc. in 2004. In 1991, Pendragon won the Origins Award for Best Roleplaying Rules of 1990.

It uses fairly traditional game mechanics for normal play, based to some degree on Basic Role-Playing, but also has a set of charts and tables for determining what happens to a character's family in between adventures.

Conventionally, the characters will have one adventure per year, and campaigns often carry over into the next generation, with the player retiring their character and playing his eldest son. This is in contrast to most role-playing games, where one set of characters are played fairly intensively, and there is typically little consideration made of what happens to their family or descendants.

The first edition, from Chaosium, copyright 1985, Greg Stafford consisted of a solid box with a full colour map of Britain. The books Player's Book and Game Master's Book, and a number of ready reference sheets.

The fourth edition, reprinted by Green Knight Publishing, came as a thick single manual, King Arthur Pendragon.
