Leonarda Cianciulli (18 April 1894 – 15 October 1970) was an Italian serial killer. Better known as The Soap-Maker of Correggio (Italian: la Saponificatrice di Correggio), she murdered three women in the town of Correggio, Reggio Emilia, in 1939 and 1940, and turned their bodies into soap (using caustic soda) and teacakes.
