The Queen of Hearts is a fictional character and the main antagonist in the 1865 book Alice's Adventures in Wonderland by Lewis Carroll. She is a childish, foul-tempered monarch whom Carroll himself describes as "a blind fury", and who is quick to give death sentences at even the slightest of offenses. One of her most famous lines is the oft-repeated "Off with his/her head!" / "Off with their heads!"
