What is the name of the card queen in the 1951 film?

The card queen in the 1951 film is the Queen of Hearts.

She rules Wonderland as a volatile and authoritarian monarch, turning minor offenses into threats of execution. Her most famous command is “Off with their heads!”, and her temper drives much of the film’s climax after Alice enters the royal garden.

The Queen first appears after gardeners discover that they have planted white roses and are painting them red. She then forces Alice into a chaotic croquet match using flamingos as mallets and hedgehogs as balls. The game is deliberately unfair, reflecting the Queen’s arbitrary power rather than any real sporting contest.

A frequent source of confusion is the Red Queen, who is a separate character in Lewis Carroll’s Through the Looking-Glass. Disney’s 1951 film combines or borrows elements from Carroll’s books, but its playing-card monarch is specifically the Queen of Hearts, voiced by Verna Felton.
