Louise Quack is a character that appears in the Sonic the Hedgehog comic book series and its spin-offs. She was a Mobian duck, the sister of Hubert and Duane Quack and the only daughter of Elizabeth Quack and Horatio Quack.
- Like the other Quack children, Louise's name is based off one of Donald Duck's nephews: in this case, Louie. Unlike her brothers, however, she does not share her gender with her "namesake".
