List of role-playing game designers

This is a list of individuals who have designed one or more role-playing games, including live-action role-playing games but excluding role-playing video games (see List of video game industry people and its children for video game creators). Artists are listed separately on the annotated List of role-playing game artists. 
The design of role-playing games may include the creation of game systems, game settings and scenarios for roleplaying; game designers engage in one or more of these activities as they create, revise and develop roleplaying games. For each designer, this list includes a few representative games, game lines or publications that the designer in question has created or co-authored or where they are credited with a significant contribution.
