Flávia Saddy is a Brazilian voice actress, dubbing director, and sports announcer, recognized for her extensive work in the Brazilian Portuguese dubbing of international films and television series. Born on December 12, 1978, in Rio de Janeiro, Brazil, she was born into a family with a strong legacy in voice acting, as the daughter of Marlene Costa and the sister of Fernanda Baronne, both established voice actresses in the industry.

Her career in dubbing began in childhood, with her debut at the age of 11 in the Brazilian adaptation of the telenovela Carrossel. This early start, facilitated by her family's involvement in the field, laid the foundation for a decades-long career. Over the years, she has become a prominent and respected figure in Brazilian dubbing, known for her versatility and expressive performances. Beyond voice acting, Saddy has also taken on roles as a dubbing director for series such as Sex Education and Slasher, and has worked as a sports narrator since 2008.

Saddy is perhaps best known for her long-running role as the voice of Lisa Simpson in the Brazilian Portuguese dub of The Simpsons, a character she has voiced since the early 2000s. She is also the official Brazilian voice for the character Barbie in numerous animated films and, notably, for Margot Robbie's portrayal of the character in the 2023 live-action film Barbie. Her other high-profile live-action dubbing work includes voicing Wonder Woman (played by Gal Gadot) in the DC Extended Universe films and Mia Colucci in the popular telenovela Rebelde.

In the realm of animation and anime, Saddy's contributions are equally significant. She has provided the Brazilian Portuguese voice for a wide array of characters, including Lin in the Studio Ghibli film Spirited Away, Jessie in various Pokémon productions, Stormy in Winx Club, and Daphne Blake in Scooby-Doo projects. Her talent has been recognized with two Prêmio Yamato awards, often referred to as the "Oscar of Dubbing" in Brazil, for her supporting voice work in Smallville and The Simpsons Movie.
