Big Brother Brasil 21 is the twenty-first season of Big Brother Brasil, which premiered on TV Globo on January 25, 2021. The show is produced by Endemol Shine and presented by Tiago Leifert. The new season was confirmed by Leifert and the show director, Boninho, on April 27, 2020, on the day of the live finale of Big Brother Brasil 20.

The grand prize is R$1.5 million with tax allowances, a R$150,000 prize is offered to the runner-up and a prize of R$50,000, to the third place. Just as the previous season, this season features 20 housemates divided into two groups: "Celebrities", composed of actors, singers, professional athletes and social media personalities, and "Civilians" composed of everyday Brazilians.

On May 4, 2021, lawyer & makeup artist Juliette Freire won the competition with 90.15% of the public vote over digital influencer Camilla de Lucas and actor & singer Fiuk. According to the Brazilian Institute of Public Opinion and Statistics, the first episode was watched by 43.7 million viewers, and in total 65 million tuned in during the first week.

The game #FeedBBB The theme of the reality show is such that each housemate will use a cellphone to capture moments in the house during a time determined by the production. The cell phone only allows them to post photos and videos to #FeedBBB, and see what other housemates say about each other. It does not allow contact with the outside world.

FeedBBB introduced an app akin to Tinder called "Arrow" in season twenty-one, which housemates used to pick out their love interests in the house. The "HoH Podcast" is recorded weekly and published on the GShow website. The housemates can see when it is being recorded but do not hear the content.

Nomination Superpower Starting on the day the cast list was unveiled, the public voted to grant three "Civilians" and three "Celebrities" immunity from the first eviction period. The six selected housemates lived in a House Next Door and joined the Main House on Day 2. Then, one housemate was nominated for eviction.

Fake Eviction On week 6, it was announced that there would be a fake eviction. The winner of the Head of Household competition during week 6 would be given immunity during the following week. All final nominees guarantee their spot in the next competition. Instead of voting to evict, the audience would be voting to give powers to two housemates, the most voted and the least voted.

Secret Room & Power of Immunity Veto The most voted housemate is moved to a secret room and given a Power of Immunity Veto. This gives them the power to cancel the decision of the Power of Immunity Holder. This power is valid for two weeks and may only be used once.

Double Vote The least-voted housemate is given a Double Vote. This means that, in the Diary Room, their one vote is counted as two votes. This power is valid for two weeks and may only be used once.

Super HoH Along with its regular powers, the HoH would also be tasked with splitting their housemates into Haves and Have-Nots as well as choosing what and how much each group would be eating.

Power of Veto In some weeks, the nominated housemates compete against each other for one last chance to save themselves from eviction. The housemates nominated by the HoH are not eligible to compete and are guaranteed to face Brazil's vote.

Power of No At the beginning of each week, the previous Head of Household may or may not be given the opportunity to disqualify some housemates from competing in the upcoming HoH competition.

The Counterattack The counterattack is a surprise power given to either the HoH's nominee and/or the House's nominee in which they have the opportunity to automatically nominate an additional housemate for eviction. While viewers are informed when the power will be featured in advance (on Thursdays before the Head of Household competition even takes place), the housemates are only informed about the twist on the spot, during Sunday's live nominations.
