Recurring characters

NYPD and other law enforcement

• Patton Oswalt as FDNY Fire Marshal Boone, the fire marshal of the local fire station. He leads the fire department in a rivalry against the detectives of the 99 but reaches a brief understanding with Jake when they discover that they both were abandoned at a young age by their fathers.
• Dean Winters as Detective Keith Pembroke, nicknamed "The Vulture", an obnoxious detective in the Major Crimes Unit notorious for taking over cases that are nearly solved and receiving all of the credit for closing them. He frequently makes lewd comments toward the squad and has a greatly inflated sense of self. After the death of Seth Dozerman, Pembroke becomes the Commanding Officer of the 99th Precinct until Captain Holt returns. He treats the squad with huge disrespect, for example expecting them to clean up after him. In "The Venue", the Vulture steals Jake and Amy's venue at the last second to host his wedding to a kind charity worker named Jean Munhroe. When the two discover that he is unfaithful to Jean and lying to her about his character, they decide to tell Jean at the cost of the Vulture taking their venue on their wedding night. He is a recipient of the American Flag Breast Bar, World Trade Center Breast Bar, NYPD Medal of Honor, and Marine Corps Service Award.
• Kyle Bornheimer as Sergeant Teddy Ramos, a detective at the 82nd Precinct. Teddy used to date Amy Santiago; they resume their relationship after meeting up at a training exercise. Later Amy breaks up with him again, because she dislikes his dull personality and is unable to show interest in his home pilsner-brewing hobby. In season four, Teddy evaluates the Nine-Nine when the crime rate drops and one precinct has to close. He claims to have changed but Jake and Amy agree that he is still "The most boring man in America". He also admits to Amy that he still loves her and proposes to her several times over the next few seasons. In season five, Teddy has joined the bomb squad to impress Amy and tries unsuccessfully to steal her away from Jake on the day of their wedding. By season 7, Teddy is now married and took his wife's name, Ramos. Despite the couple expecting a child, he is still romantically interested in Amy.

• Jason Mantzoukas as Adrian Pimento, an emotionally unstable and volatile former detective who returned to the 99th Precinct after spending 12 years undercover in the organization of Jimmy "The Butcher" Figgis. He began dating Rosa in "Cheddar", and the two got engaged in "Paranoia", promptly before Pimento and the 99 were forced to fake his death. Pimento returns from hiding when Jimmy "The Butcher" Figgis is caught, but is refused his old job at the NYPD and becomes a Private Investigator. His relationship continued with Rosa, but she later breaks up with him in season five.

In "Pimemento", it is revealed that he has worked for celebrities before as a private investigator.
• James M. Connor as Deputy Commissioner Podolski, the NYPD's arrogant deputy police commissioner who uses his position for his own personal means such as keeping his rebellious son, Trevor, out of jail in "The Tagger".
• Michael G. Hagerty as Captain McGintley, the 99th Precinct's commanding officer before Raymond Holt, who was fired for his ineptitude and his permissive attitude toward the disruptive antics of Jake and his colleagues. McGintley later died in the episode "99" and the squad attended his funeral in Los Angeles.
• Kyra Sedgwick as Madeline Wuntch, a callous and unethical NYPD deputy police chief who shared a deep mutual hostility with Captain Holt. Wuntch and Holt were once partners and friends, but they fell out after Holt rejected her sexual advances and Wuntch gained promotions for which Holt was passed over, resulting in Wuntch eventually becoming Holt's direct superior. Wuntch constantly went out of her way to undermine the 99th Precinct, and appeared to take great pleasure in its and Holt's failures; Holt, in turn, gleefully insulted and belittled Wuntch every time their paths cross. In "The Chopper" and "Johnny and Dora", she culminated her victory over Holt when she makes him head of the NYPD Public Affairs Division, where she humiliated him by making him do menial jobs, although he is eventually transferred back to the 99 thanks to Jake. In "Suicide Squad", she helped Jake and the Nine-Nine expose Commissioner Kelly's illegal wiretapping activity and became the acting commissioner until a new one was decided on.

It's revealed that Holt called the reporters in to help the crew return to the day shift.

• Vanessa Bayer as Debbie Fogle, Holt's partner when he gets demoted down to patrolman. She doesn't appear to have any friends and is very naive. It is later revealed that she was working for a notorious crime boss named Silvio Nucci and stole machine guns and cocaine from the evidence locker room. Jake and Rosa initially pretend to be dirty cops so they can get her to lead them to Nucci, but she defeats them both after ingesting some of the cocaine.
