Cinzia Leone is an Italian actress and voice artist, primarily known for her extensive work in film, television, and theater. Born in Rome on March 4, 1959, she began her career on stage before gaining widespread recognition as a comedic actress and impersonator on popular Italian variety shows in the late 1980s and 1990s.

Within the field of voice acting, Leone is specifically recognized for her contribution to the Italian-language adaptation of the historic anime series Mazinger Z. In the 2015 redub of the series, produced to complete the Italian version with previously unseen episodes, she provided the Italian voice for the female half of the character Baron Ashura. This character is a notable antagonist, unique for being a single entity with both a male and a female persona, voiced by Claudio De Davide for the male half and Cinzia Leone for the female half in this new edition. Her work on Mazinger Z represents one of her primary credits in the anime genre. Other dubbing work by Leone includes voicing the character Maggie in the animated film Home on the Range and providing the Italian voice for actress Pam Grier in the film Above the Law.

Leone's career in entertainment is broad and distinguished, with her work in live-action earning her a nomination for the David di Donatello award for Best Supporting Actress in 1992 for her role in the film Donne con le gonne. Her contribution to anime voice acting, however, is best documented through her role in the iconic series Mazinger Z.
