Brooklyn Nine-Nine cast and character guide: Who plays whom in the police procedural sitcom?

When Brooklyn Nine-Nine crash-landed into our lives in 2013, it didn’t just shake up the police procedural formula; it roasted it, hugged it, and gave it a high-five. Set in the buzzing chaos of the 99th precinct in Brooklyn, this sitcom follows a crew of detectives who are somehow both total disasters and the best cops in town. Logic? Optional. Heart? Always.

At its core is a childish but brilliant detective whose love for Die Hard is matched only by his knack for cracking even the toughest cases. His partner (and later, wife) is a perfectionist with an unhealthy obsession with binders and validation. Their captain? A stoic, stone-faced legend with a dry wit so sharp it could cut glass. Then there’s the leather-jacket-wearing mystery woman who might actually be a motorcycle in human form, the yogurt-fueled sergeant with a heart the size of Brooklyn, and the world’s most loyal sidekick who’d take a bullet for his best friend, and narrate the experience in culinary metaphors.

From petty precinct drama to undercover missions gone hilariously wrong, Brooklyn Nine-Nine's 99th Squad somehow manages to solve crimes, support each other, and make us laugh so hard we forget it’s a cop show. Here's everything you need to know about the cast of Brooklyn Nine-Nine and the characters they perfectly embody on screen.

Andy Samberg as Jake Peralta

Andy Samberg's Jake Peralta a detective who brings golden retriever energy to the team while also being effortlessly effective in dealing with all sorts of criminals.

From the moment he swaggered into the 99th precinct in season one, Jake was chaos wrapped in a leather jacket and armed with dad jokes, catchphrases, and an arrest record no one could argue with. He’s childlike, competitive, allergic to paperwork, and deeply committed to never growing up, at least, not without a fight.

But over the eight seasons of Brooklyn Nine-Nine, Jake does what few sitcom characters manage to do without losing their charm: he grows. Under the stoic mentorship of his captain and the patient love of his partner, he slowly swaps reckless for responsible.

His story is one of transformation without compromise; he doesn’t stop being Jake Peralta, he just becomes the version of himself that little Jake always needed. Still loud, still extra, but finally… grown. Kinda.

Stephanie Beatriz as Rosa Diaz

Stephanie Beatriz doesn’t just play Rosa Diaz, she becomes the storm in a leather jacket. With her gravel-toned voice, death-stare precision, and an aura that says “I may or may not have buried a body,” Rosa is Brooklyn Nine-Nine’s most mysterious badass. She rarely smiles, barely speaks, and somehow still manages to dominate every scene she’s in.

Rosa isn’t interested in being liked; she’s interested in being real. And through every smirk, snarl, and unexpected burst of tenderness, Stephanie Beatriz shows us that strength doesn’t always shout. Sometimes, it rides a motorcycle, flips a perp, and vanishes into the night with zero explanation. Iconic? Obviously. Unmatched? Without question.

Terry Crews as Terry Jeffords

Terry Crews brings unmatched heart and humor to Terry Jeffords, the yogurt-loving sergeant of Brooklyn Nine-Nine with a bodybuilder’s frame and a teddy bear’s soul. As the father of three girls, Jeffords balances brute strength with deep vulnerability, famously panicking at the thought of leaving his daughters without a dad.

Crews makes Jeffords a beacon of emotional intelligence, modern masculinity, and quiet leadership. Whether he's standing up to racial profiling or encouraging therapy, Jeffords proves that strength isn't just about muscles; it's about empathy. And let’s be honest, no one yells “Terry loves yogurt!” with more conviction or charm.

Melissa Fumero as Amy Santiago

Melissa Fumero doesn’t just play Amy Santiago, she embodies the caffeine-fueled chaos of every overachiever who’s ever color-coded a study guide for fun. As Brooklyn Nine-Nine's most enthusiastic rule-follower, Amy is a binder-wielding storm of ambition, constantly chasing promotions, gold stars, and her captain’s elusive approval. But beneath the rigid exterior lies a heart that’s tender, anxious, and full of growth.

Fumero brings nuance to Amy’s perfectionism, inspired by her own early nerves on set. That honesty makes Amy more than just a punchline; she’s layered, driven, and deeply relatable. Whether she’s busting bad guys or dominating the Halloween heist, she’s always ten steps ahead. Amy is proof that you can be nerdy and powerful, romantic and ruthless, and that spreadsheets do belong in every emergency.

Joe Lo Truglio as Charles Boyle

Joe Lo Truglio turns Charles Boyle into Brooklyn Nine-Nine’s most chaotic cinnamon roll, part detective, part foodie, and all Peraltiago fanboy. Boyle is the guy who’ll take a bullet for you, then cry about how beautiful the moment was. He’s awkward, oversharing, and wildly intense about both friendship and fermented meats, but his loyalty is unmatched and his instincts are surprisingly sharp.

Lo Truglio takes what could’ve been a one-note sidekick and gives him soul. Whether he’s gushing over Jake’s every move, championing niche cuisines, or stumbling into a takedown, he does it with wild-eyed sincerity. Boyle might not be exactly what one calls cool, but thanks to Lo Truglio, he’s unforgettable, the emotional glue of the Nine-Nine.

Chelsea Peretti as Gina Linetti

Chelsea Peretti doesn’t just play Gina Linetti; she channels her from an alternate dimension where sarcasm is currency and confidence is a birthright. Gina isn’t a cop, she’s a vibe. She floats through Brooklyn Nine-Nine in a haze of cryptic wisdom, elite dance moves, and the kind of chaotic brilliance that makes you question your own coolness.

Peretti’s performance is pure comedic alchemy. Gina was written around her energy; no one else could deliver lines like “The English language cannot fully capture the depth and complexity of my thoughts” with such deadpan perfection. Gina is more than comic relief; she’s the civilian heartbeat of the Nine-Nine, dropping existential truths between roast sessions and disappearing in a puff of glittery ego. She's ridiculous, iconic, and somehow always right.

---

Andre Braugher as Raymond Holt

Andre Braugher's Captain Raymond Holt redefined what comedy could look like in absolute stillness. With a face carved from stone and a voice that could command armies or announce a corgi’s birthday party, Holt is the soul of Brooklyn Nine-Nine, unshakable, principled, and dry as the Sahara.

Braugher, a seasoned dramatic actor, turned restraint into a punchline and gave weight to every single “noice.” He made Holt’s journey, as a Black, gay police captain who climbed the ranks with quiet dignity, both groundbreaking and deeply human. From delivering iconic deadpan one-liners to mentoring his chaotic squad with surprising warmth, Holt has become a sitcom icon who, instead of raising his voice, raised the bar.

---

Dirk Blocker as Michael Hitchcock

Dirk Blocker transforms Michael Hitchcock into a walking, belching monument to everything that should not work in a police precinct, and yet, somehow, in Brooklyn Nine-Nine, it does. Once a chiseled, sharp detective with a knack for busting mafia rings, Hitchcock let it all go for buffalo wings, recliner naps, and wildly inappropriate workplace commentary. He’s sleazy, slouchy, and strangely proud of having more ex-wives than working brain cells.

Still, beneath the stains and sweat, he holds the precinct’s case-closure record and the title of most disturbingly enthusiastic paper-pusher. Blocker plays him with unfiltered glee, turning Hitchcock into a legend of lazy, greasy brilliance.

---

Joel McKinnon Miller as Norm Scully

Joel McKinnon Miller takes Norm Scully, a man held together by gravy, fungi, and vibes, and turns him into Brooklyn Nine-Nine’s most unexpectedly complex couch ornament. Scully’s the guy who’ll have a heart attack mid-sentence, then casually sing opera in fluent French between donut bites. Sure, he’s lazy, always borderline septic, and disturbingly open about his foot warts, but every now and then, he drops a moral bombshell or cracks a case like it’s 1989 again.

Miller plays him with the perfect blend of clueless charm and weird wisdom, proving that under all the crumbs, Scully still slaps.
