Beatriz Oliveira is a Brazilian actress and voice actor known for her work in both live-action and animation. She gained recognition for her role as the voice of Yuki Itose in the Portuguese dub of the anime series A Sign of Affection. This project marked her debut in the voice acting industry.

Oliveira is an oral deaf actress who began losing her hearing at the age of seventeen due to otosclerosis. She subsequently began using a hearing aid and learned Brazilian Sign Language.

She played Pórcia in the SBT and Amazon novel A Infância de Romeu e Julieta.
