The 23rd season of Big Brother Brasil, also known as BBB23, is a reality television show that is currently airing in Brazil. The show is based on the international franchise Big Brother, in which a group of contestants, known as "housemates," live together in a specially-constructed house, isolated from the outside world but continuously monitored by cameras and microphones. Throughout the show, housemates compete in various challenges and tasks, and are eliminated until only one remains and is declared the winner.

Assistir Big Brother Brasil premiered on January 25, 2021 and is being broadcast on the television network Globo. The show is hosted by Tiago Leifert, and the housemates are competing for a grand prize of R$1.5 million (Brazilian reals).

The housemates are a diverse group of individuals, representing different regions of Brazil and with varied backgrounds, such as models, athletes, and entrepreneurs.

The show has a strong online presence, where fans can follow the housemates' daily lives and vote for their favorite contestants. There are also several spin-off shows and special segments that air throughout the week, in which fans can get to know the housemates better and see behind-the-scenes footage.
