Brooklyn Nine-Nine built its enduring legacy on brilliant ensemble chemistry, sharp writing, and an endless parade of hilarious cold opens. While Andy Samberg, Andre Braugher, and the rest of the core precinct members carried the narrative across its eight seasons, the show also relied heavily on a rotating roster of guest stars. Beyond the recurring fan favorites like Craig Robinson’s Doug Judy or Jason Mantzoukas’s Adrian Pimento, the series frequently drew unexpected talent from comedy, drama, music, and blockbuster cinema.
Reviewing these appearances reveals a fascinating cross-section of actors who dropped by the Nine-Nine for a single episode or a short arc. Some of these names were on the cusp of superstardom just before their breakout roles, while others were iconic veterans who delighted audiences by playing completely against type. Examining these 10 surprising guest stars highlights the impressive industry pull of creators Dan Goor and Michael Schur, showcasing how a beloved police sitcom became an unexpected destination for top-tier talent.
1. Sterling K. Brown ("The Box" — Season 5, Episode 14)
Long before he was a household name leading critically acclaimed dramas, Sterling K. Brown delivered one of the most intense, critically lauded guest performances in television history on Brooklyn Nine-Nine. In "The Box," Brown plays Philip Davidson, a brilliant, ice-cold dentist suspected of murdering his business partner.
Instead of a typical comedic romp, the episode functions as a high-stakes, bottle-episode psychological chess match between Davidson, Jake Peralta, and Captain Holt. Brown’s ability to pivot from polite professional to chillingly detached suspect earned him widespread praise, including a Primetime Emmy Award nomination for Outstanding Guest Actor in a Comedy Series. It remains a masterclass in dramatic acting within a half-hour comedy format.
2. Bill Hader ("New Captain" — Season 3, Episode 1)
Coming off his legendary run on Saturday Night Live and right before creating his dark HBO masterpiece Barry, Bill Hader stepped into the precinct as Captain Seth Dozerman. Dozerman was introduced as Holt's short-lived, efficiency-obsessed replacement who measured everything in seconds and unfortunately died of a heart attack during his second episode after discovering Jake and Amy kissing.
Hader’s appearance was brief, but his deadpan delivery of corporate management buzzwords and his intense obsession with workplace optimization left a permanent mark. His character set the chaotic tone for the revolving door of leadership changes that plagued the Nine-Nine at the start of Season 3.
3. Maya Rudolph ("The Fugitive" — Season 4, Episodes 11 & 12)
Another Saturday Night Live alumnus, Maya Rudolph, brought her unmatched comedic energy to a two-part special arc as United States Marshal Karen Haas. Tasked with protecting Jake and Rosa during their stint in witness protection in Florida, Haas is meant to be a strict, professional law enforcement officer.
Instead, Rudolph plays her with a brilliantly chaotic exhaustion, desperately trying to manage two reckless detectives while dealing with her own mundane personal crises and deep love for cheap wine. Her chemistry with Andy Samberg and Stephanie Beatriz grounded the ridiculous Florida-set storyline with grounded, top-tier improvisational comedy.
4. Sandra Oh ("The Jimmy Jab Games" — Season 2, Episode 3)
Years before Killing Eve catapulted her into international prestige television stardom, Sandra Oh made a memorable appearance as Deputy Chief Joanne Stupnick. In "The Jimmy Jab Games," Stupnick arrives at the precinct to oversee a high-profile visit, forcing the detectives to hide their clandestine internal competition.
Oh plays the role with a sharp, professional severity that contrasts hilariously with the immature chaos unfolding behind her back. Though her screen time is relatively short, her authoritative presence anchored the episode's central administrative pressure, giving the detectives a formidable bureaucratic hurdle to clear.
5. Neil deGrasse Tyson ("The Audit" — Season 4, Episode 4)
In one of the most bizarrely delightful cameos in the show's history, renowned astrophysicist and science communicator Neil deGrasse Tyson appeared as himself. When Terry Jeffords runs into trouble with his alma mater or encounters academic hurdles, Tyson shows up to provide unsolicited, highly condescending scientific reality checks.
Rather than treating his cameo as a standard polite talk-show-style guest spot, the show leans into Tyson’s distinct public persona, letting him ruthlessly mock Terry’s intellectual shortcomings. It is a delightfully surreal moment that highlights the show's willingness to bend reality for a quick, high-concept laugh.
6. J.K. Simmons ("The Fugitive" — Season 4, Episode 11)
Academy Award winner J.K. Simmons brought his signature booming intensity to the Season 4 winter premiere, playing Detective Frank Dillman. Dillman is a legendary, borderline mythical NYPD investigator whom Jake and the squad idolize for his immaculate track record and terrifying attention to detail.
When a major incident occurs at the precinct, Dillman is brought in to interrogate the staff. Simmons plays the role with the same relentless, terrifying psychological pressure he brought to Whiplash, making a workplace comedy episode feel momentarily like a high-stakes psychological thriller. Watching the squad panic under his gaze remains a comedic highlight of the middle seasons.
7. Zooey Deschanel ("The Night Shift" — Season 4, Episode 4)
While technically part of a heavily promoted network crossover event, Zooey Deschanel’s appearance as her New Girl character, Jessica Day, deserves a spot for sheer unexpected narrative collision. During a chaotic car chase through New York City, Jake commandeers a cab, only to find Jessica Day behind the wheel.
For a few fleeting moments, the universes of two completely different Fox comedies collided. Deschanel’s signature quirky, upbeat optimism clashed hilariously with Jake’s high-stress criminal pursuit, offering a fun treat for fans of 2010s network sitcom blocks.
8. Patton Oswalt ("The Honeypot" — Season 2, Episode 8)
Comedian, actor, and pop-culture icon Patton Oswalt appeared as Fire Marshal Boone, the precinct’s bitter, petty rival from across the hall. The running feud between the NYPD and the FDNY is a classic New York trope, and Oswalt leaned into the pettiness with unmatched enthusiasm.
Boone’s rivalry with Jake and Captain Holt turns into a bureaucratic war of attrition, filled with passive-aggressive pranks and petty jurisdictional disputes. Oswalt’s natural talent for playing intensely defensive nerds made him the perfect foil for the structured, dignified Holt.
9. Mario Lopez ("The Chopper" — Season 2, Episode 22)
In the Season 2 finale, Extra host and former Saved by the Bell star Mario Lopez appeared as himself, getting swept up in Terry and Charles's frantic investigation. The precinct encounters Lopez at a public event, leading to a surreal sequence where the detectives try to leverage his celebrity status to solve a crime.
Lopez played along with the joke brilliantly, poking fun at his own public persona as an omnipresent media personality. It added an authentic layer of New York media culture to the precinct's chaotic final episodes of that season.
10. Bradley Whitford ("Captain Peralta" — Season 2, Episode 21)
Rounding out the list is Emmy winner Bradley Whitford, who took on the crucial recurring role of Roger Peralta, Jake’s charming, emotionally unavailable, and frequently criminal airline pilot father. While Whitford appeared in multiple episodes, his introduction in Season 2 fundamentally reshaped our understanding of Jake’s psychological baggage.
Whitford balances roguish charm with deeply frustrating paternal neglect, making it completely understandable why Jake spent his entire life chasing his approval. The complex dynamic between father and son gave the comedy considerable emotional depth, proving that the show could handle dramatic family reconciliation just as well as fast-paced gags.
