Jeanne Van Calck (17 September 1897 – 7 February 1906), also known as Joanna, was a Belgian child murder victim, whose case became a symbol for childhood innocence. Her dismembered body was found on the evening of 7 February 1906, at 22 Rue des Hirondelles in Brussels. Her murder, now known as the Murder of Rue des Hirondelles, was never solved.
