Oriental Adventures (abbreviated OA) is the title shared by two hardback rulebooks published for different versions of the Dungeons & Dragons (D&D) fantasy roleplaying game. Each version of Oriental Adventures provides rules for adapting its respective version of D&D for use in campaign settings based on the Far East, rather than the medieval Europe-setting assumed by most D&D books. Both versions of Oriental Adventures include example campaign settings.
