The Pathfinder Roleplaying Game is a fantasy role-playing game (RPG) that was published in 2009 by Paizo Publishing. The first edition extends and modifies the System Reference Document (SRD) based on the revised 3rd edition Dungeons & Dragons (D&D) published by Wizards of the Coast under the Open Game License (OGL) and is intended to be backward-compatible with that edition. The first major revision of the ruleset, Pathfinder 2nd Edition, was released in August 2019.
Pathfinder is supported by the official Pathfinder periodicals and various third-party content created to be compatible with the game.
