Jacqueline Sato is a Brazilian actress, presenter, and voice actor known for her work dubbing anime films and series for the Brazilian Portuguese market. Born in Guarulhos, São Paulo, on September 21, 1988, she began her entertainment career in the late 1990s as a television presenter before transitioning to live-action acting in telenovelas and series for major Brazilian networks like Rede Globo.

In the realm of anime voice acting, Sato has been cast in prominent roles for several theatrical releases distributed in Brazil. She voiced Melissa Shield in the 2018 film My Hero Academia: Two Heroes, a role she described as a challenging and enjoyable experience that required her to apply her acting skills to create a voice that matched the character's essence. She returned to the My Hero Academia film franchise to voice the character Slice in My Hero Academia: Heroes Rising. In 2019, she took on the role of Dr. Serena in the preschool-oriented anime series Go Astro Boy Go. The following year, she was cast as the iconic femme fatale Fujiko Mine in the Brazilian dub of the 3D CGI film Lupin III: The First.

Sato's work in dubbing often involves collaboration with Sato Company, a Brazilian distribution company that has brought numerous anime titles to the country, including the My Hero Academia films and Lupin III: The First. For My Hero Academia: Two Heroes, she worked under the direction of renowned Brazilian voice actor Úrsula Bezerra at the UniDub studio. Sato has noted the technical demands of dubbing, such as syncing her performance to the on-screen character's lip movements and timing while maintaining emotional truth, a process she approaches with the same commitment as live-action acting. Her casting in high-profile anime franchises represents a crossover from her established career in Brazilian television and film into the world of voice acting for anime.
