This is a list of campaign settings published for role-playing games. Since role-playing games originally developed from wargames, there are many historical and alternate-history RPGs based on Earth. The settings for such games are excluded from this list, unless they include significant fictional elements. Many RPG campaign settings are based on fictional universes from books, comics, video games, or films. Campaigns have been created for Star Wars, Lord of the Rings, Star Trek, and James Bond, for example.
