Thadeu Matos is a Brazilian voice actor and former child actor known for his work in animation, television series, and video games. He began his career in front of the camera at a young age, gaining national recognition in Brazil for his role as Bruno in the telenovela Senhora do Destino in 2004 when he was twelve years old. Following this early television success, Matos shifted his focus to the performing arts, earning a degree in theater from the Federal University of the State of Rio de Janeiro (UNIRIO). He eventually transitioned into voice dubbing, a field where he has become best known.

In anime, Matos is recognized for providing the Brazilian Portuguese voice of Shinji Koganei in the popular sports series Kuroko's Basketball. His character is a small forward for Seirin High School, noted as a skilled all-around player with an unusually accurate but unremarkable shooting ability. Outside of anime, his voice dubbing roles include Dr. Spencer Reid in Criminal Minds and Hughie Campbell in The Boys. His career demonstrates a transition from live-action child stardom to a consistent career as a voice actor in Brazilian dubbing.
