Patt Souza is a Brazilian voice actress known for her extensive work in dubbing anime and other animated content into Portuguese. Her birth date is recorded as October 24, 1985. She is also known professionally as Patrícia Souza.

Souza has built a career voicing prominent characters in several major anime series. Some of her most notable roles include Jolyne Kūjō in JoJo's Bizarre Adventure: Stone Ocean, Pieck Finger in Attack on Titan The Final Season, Mina Ashido in My Hero Academia, Nikaido in Dorohedoro, and Brunhild in Record of Ragnarok. Her filmography also includes characters such as Mitsuri Kanroji in Demon Slayer: Kimetsu no Yaiba, Kurotsuchi in the Boruto and Naruto Shippūden series, and Dr. Arinsu in Dragon Ball Daima. She has also voiced Levy McGarden in Fairy Tail and its related film.

In a 2021 interview, Souza discussed her approach to character creation, explaining that she draws from the original performance while adding her own interpretation based on the character's described traits and her personal repertoire of character types. She noted that for her role as Cassandra Dimitrescu in the video game Resident Evil Village, she recorded her lines without having seen the character's final design, learning about her role through the director's guidance and the creative brief for the character. Her process often involves recording in a studio setting, though remote recording has also become a part of her workflow.

Souza frequently collaborates with dubbing studios such as Unidub, which produced the Portuguese versions of series like Record of Ragnarok and Dorohedoro where she voiced lead roles. Her work on Dorohedoro as Nikaido, alongside Marcelo Salsicha as Caiman, marked one of the first times both voice actors took on protagonist roles in an anime series. Beyond animation, her voice work extends to live-action series and video games. She provided the Brazilian Portuguese voice for Jennifer Walters in the Disney+ series She-Hulk: Attorney at Law and voiced both Cassandra Dimitrescu and Rose in the video game Resident Evil Village.
