荒唐分局第六季

The sixth season of the television sitcom Brooklyn Nine-Nine premiered on January 10, 2019 on NBC and concluded on May 16, 2019. This is the first season to air on NBC (whose partner studio Universal Television produces the show), as the series was canceled on May 10, 2018 by Fox. NBC picked it up for a sixth season shortly after the series had been canceled on May 11, 2018. The season consists of 18 episodes.

Holt finds out he lost the commissioner position to John Kelly and is sent into a deep depression until Jake and Amy encourage him to stand up to Kelly's regressive policies, resulting in the new commissioner retaliating against the Nine-Nine. Gina quits her job after deciding that her talents would be better spent elsewhere and becomes a successful internet celebrity. Amy and Jake debate on whether they want kids or not. Terry passes the Lieutenant's Exam, and wins the "Cinco de Mayo" Heist aka Halloween Heist for the first time. However the Nine-Nine doesn't have enough funds for him to stay and he finds out that he might be transferred to Staten Island.

Jake and Holt discover that Kelly is using his new anonymous tip app to illegally wiretap the population, forcing them to recruit some of their old rivals to help expose his crimes. Thanks to Jake and Wuntch staging an arrest for a fake kidnapping, Kelly is suspended and Wuntch becomes the acting commissioner. She uses her new position to allow Terry to stay at the Nine-Nine and force Holt to make up for his missing patrol officer days.

On May 10, 2018, it was announced that Fox had canceled Brooklyn Nine-Nine. Following the announcement, other networks including Netflix, Hulu, and TBS expressed interest in picking up the series for a sixth season. However, it was subsequently reported that all three networks had declined to pick up the series. A hashtag supporting the renewal of the series also became the number-one trend on Twitter.

On May 11, 2018, the day after the announcement of its cancellation, NBC officially picked up the series for a thirteen-episode sixth season. An NBC executive stated about the series, "Ever since we sold this show to Fox I've regretted letting it get away, and it's high time it came back to its rightful home." On September 7, 2018, NBC ordered five additional episodes for the season, increasing the episode total to eighteen.

All current main cast members returned for the sixth season. On October 3, 2018 Chelsea Peretti announced that she would depart the series during the sixth season. Her final scene was filmed in the first full week of November 2018. Peretti's final episode as a main cast member was the fourth episode, entitled "Four Movements"; she returned to the series as a guest star in the fifteenth episode, "Return of the King."

Season 6 marks the first season that features episodes directed by a main cast member. Stephanie Beatriz directed the episode "He Said, She Said", which was inspired by the Me Too movement and focuses on the investigation of a sexual assault. Joe Lo Truglio directed the thirteenth episode, titled "The Bimbo" and Melissa Fumero directed "Return of the King", which focuses on the return of Chelsea Peretti's character, Gina Linetti.

The season premiered as a mid-season replacement in the middle of the 2018–19 television season. It aired on Thursdays at 9:00 pm from January 10, 2019.

The sixth season received mostly positive reviews, who praised the many guest stars and the John Kelly storyline, although the pacing received a mixed response. The review aggregator website Rotten Tomatoes reports a 100% approval rating, with an average score of 8.32/10, based on 27 reviews. The website's consensus reads, "Following a period of uncertainty and a shift to NBC, Brooklyn Nine-Nine reemerges with its cast and tone wholly intact."
