A "campaign" is a series of individual adventures, and a "campaign setting" is the world in which such adventures and campaigns take place. Usually a campaign setting is designed for a specific game (such as the "Forgotten Realms" setting for "Dungeons & Dragons") or a specific genre of game (such as Medieval fantasy, or outer space/science fiction adventure).
