Ra's al Ghul is a title used by the leader of the League of Assassins, and so it may refer to various characters:
  • An unnamed man, the predecessor to another unnamed but prominent man
  • "Ra's al Ghul", whose real name was not revealed.
  • Malcolm Merlyn, who took up the mantle of Ra's al Ghul after receiving the previous leader's ring from Oliver Queen.

Additionally, Oliver Queen and Nyssa Raatko briefly held the title at different times.
