What is the full name of the woman who falsely accuses Tom Robinson?

The woman who falsely accuses Tom Robinson is Mayella Violet Ewell. She is the nineteen-year-old daughter of Bob Ewell and the oldest of the Ewell children in To Kill a Mockingbird.

Mayella claims that Tom raped her, but the courtroom evidence shows that her story is false. Atticus Finch demonstrates that Tom's unusable left arm makes the alleged assault unlikely, while Mayella's injuries suggest that she was attacked by someone left-handed—most plausibly her father, Bob.

Mayella's accusation reflects both personal fear and the racist social order of Maycomb. She is isolated, poor, and abused, but the false accusation still places Tom in grave danger because the town's institutions are shaped by racial prejudice. Her testimony becomes one of the novel's clearest examples of how fear and shame can produce devastating injustice.

Readers sometimes answer Bob Ewell because he helps promote the accusation. Bob is the father and a key accuser, but Mayella is the woman who makes the allegation in court.
