Fleance is a character in William Shakespeare's 1606 play Macbeth. In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches. After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be. Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes. Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.
