[[caption-width-right:329:Badge? Check. Lab coat? Check. They fight crime.]]

->''"Look, I'll do my street thing, you do your lab thing, alright? Together, we catch bad guys."''
-->-- '''Seeley Booth''', ''Series/{{Bones}}''

The classic BuddyCopShow formula usually involves two law-enforcement officers with very different methods pairing up to fight crime. Older versions usually involve a ByTheBookCop working with a CowboyCop. They will form an OddCouple due to their views of regulation.

In recent years, new shows have partnered Cops and Scientists. Rather than squabbling over regulations, their OddCouple differences come from their roles in each investigation, which brings out differences in personality. This may have something to do with [[FollowTheLeader the success]] of the ''Series/{{CSI}}'' franchise, which highlighted the scientific side of law enforcement.

The Cop will deal with the elements of police work that involve dealing with other people such as interrogations, arrests, and dealing with [[DaChief superiors]]. If a fight breaks out, it will be the Cop who does the heavy lifting. The Cop will usually be BookDumb but StreetSmart.

The Scientist will usually be more of an ivory-tower intellectual with little practical experience in law enforcement. They will usually have personality quirks or NoSocialSkills (except when they're [[GentlemanAndAScholar one-on-one with the cop]]). They might also be a StrawVulcan. They will handle the CSI-style parts of the investigation and rarely do anything physical. If they interact with witnesses, suspects, or superiors, they'll either keep quiet or end up making things worse. Usually, HilarityEnsues.

Despite their differences, both halves of the team come to respect each other and become an effective crime-fighting force. '''Big bonus''' whenever either of them pulls off an act corresponding to the ''partner's'' expertise, at a critical point. [[note]]The Scientist does not need to become a BadassBookworm; becoming a CowardlyLion, where they overcome a persistent issue to get the Cop out of danger, is usually their big SugarWiki/MomentOfAwesome. The Cop does not need to be a GeniusBruiser; being StrongAndSkilled enough to uncover and act on the key clue that even the Scientist didn't catch is usually their own big moment.[[/note]]

It's important to remember that, to count as this trope, the Cop and the Scientist must have roughly equal focus. They must be ''partners''. While many crime-themed shows have both cops and scientists, they might focus more on one or the other. If so, then that show does not count as this trope.

Could be a form of BrainsAndBrawn. Compare AndroidsAndDetectives.

[[folder:Films -- Live Action]]
* In ''{{Film/I Robot}}'', Detective Spooner (Will Smith) is the gritty, cyborg cop and Dr. Susan Calvin (Bridget Moynahan) is the cold but beautiful robotics expert. They're investigating the death of another scientist, Dr. Lansing (James Cromwell), who played a significant role in both of their lives.
* In ''Film/LiveFreeOrDieHard'', [=McClane=] (Bruce Willis) is an experienced police officer with a checkered past, and Farrell (Justin Long) is a "grey hat" hacker on the run from both police and organized crime. They join forces against a tech-savvy terrorist who's trying to kill them first.
* ''Film/OnceUponASpy'': Paige Tannehill is a TuxedoAndMartini secret agent with a licence to kill. Jack Chenault is wisecracking genius computer scientist. Together they fight crime (and [[SavingTheWorld save the world]]).
* Barrett Coldyron of ''Film/{{ROTOR}}''combines both roles in one character.
* ''Film/WildWildWest'' features Jim West (played by Creator/WillSmith) as the Cop while Artemis Gordon is the Scientist.

[[folder:Literature]]
* Earlier books in ''Literature/TheDresdenFiles'' have a Cop and ''Wizard'' dynamic, with Karen Murphy (the cop) hiring Harry (the wizard) as a consultant when she has to work a case involving magic.
* The Temperance Brennan novels by Kathy Reichs, which ''Series/{{Bones}}'' is based on, have Dr.Brennan the scientist and her on again off again boyfriend Detective Andrew Ryan (no, not [[VideoGame/{{Bioshock}} that one]]).
* Fred Vargas' novels often feature this dynamic; Adamsberg is an unusual cop, almost a {{Cloudcuckoolander}} relying mostly on his intuition, but he often needs help from people with a deep expertise in various fields, be they archeologists like Mathias, or fellow officers like Voisenet or Danglard who spend most of their free time (sometimes even their working time) in various scholarly pursuits. ''This Night's Foul Work'' also has Adamsberg working closely with Ariane Lagarde, a medical examiner who's also unusually knowledgeable about medieval recipes for immmortality, like the one behind the crime spree she helps Adambserg investigate.

[[folder:Live-Action TV]]
* ''Series/{{Astrid}}'': The main duo consists of Commander Raphaëlle Coste, a CowboyCop detective of the French judicial police, and Astrid Nielsen, an autistic archivist at Criminal Records who became interested in criminology as a young girl.
* Also seen on ''Series/BodyOfProof'', where the scientist (Dana Delany) has both her usual medical investigator (the blonde guy) and some actual cops whose cases she usually ends up working on (the fat guy and the black woman).
* ''Series/{{Bones}}'' has Booth and Brennan, the cop and scientist respectively.
* For a [[Administrivia/TropesAreFlexible loose interpretation]] of the trope, ''{{Series/Castle|2009}}'' is a novelist partnered with Detective Beckett (This arrangement is so he can get inspiration for his books. He was able to make it happen because he's friends with the Mayor.) In a variation, both have considerable people skills, but in different areas.
* ''Series/CriminalMinds'': Unusual example, Reid is one of the FBI agents, but his extensive knowledge allows him to also act as the scientist when they need it.
* The ''Franchise/CSIVerse'' series all have elements of this.
** Captain Jim Brass in the original ''{{Series/CSI}}'' borderlines this since he had been the Crime Lab Supervisor at one time.
** ''Series/CSIMiami'''s resident non-scientist, Det. Frank Tripp, functions in a supervisory capacity.
** ''Series/{{CSINY}}'': Homicide Det. Don Flack works alongside the scientist detectives under Mac, making the policework and science more equal than in its sister shows.
* Both the UK and American versions of ''Series/EleventhHour'' feature a scientist teamed with a law enforcement officer/bodyguard (from Special Branch in the UK and the FBI in the US).
* ''Series/{{Eureka}}'' has Sheriff Jack Carter and the entire town of Eureka, which is populated by {{Mad Scientist}}s. The typical episode involves one of the town's scientists accidentally causing a strange problem and Jack working with the scientists to solve it. [[JackOfAllTrades Henry]], who is also the coroner/forensics expert is usually the scientist to Carter's cop.
* While ''Series/TheFlash2014'' isn't really about this trope, sometimes investigations fall into the same pattern due to main characters Barry Allen (CSI) and Det. West. Until Barry becomes The Flash, that is.
* ''{{Series/Forever|2014}}'' stars Dr. Henry Morgan, a medical examiner, and his partner, Jo Martinez, a streetwise detective. Shows the evolution of the trope, as the Cop and Scientist back and forth serves as more of a backdrop to the more central focus on Dr. Morgan's immortality.
* ''Series/{{Fringe}}'' has ActionGirl Agent Dunham and CloudCuckoolander in residence Dr. Walter Bishop working together to solve bizarre crimes. Somewhere in the middle fall Watler's son Peter (who's neither scientist nor law enforcement, but his experiences have left him with a decent foundation of both book and street smarts) and Olivia's assistant Astrid Farnsworth (an FBI researcher who is technically an agent but mainly assists Walter in the lab).
* ''Series/{{Galileo}}'', with police detectives Kaoru and Misa (in their respective seasons) and physicist Manabu Yukawa, the titular Galileo.
* NBC's ''{{Series/Hannibal}}'', based on ''Literature/RedDragon'', in which Will Graham partners with psychiatrist Hannibal Lecter, not knowing that Lecter is himself a serial killer.
* ''{{Series/Instinct}}'': Lizzie Needham is an NYPD homicide detective. Dylan Reinhart is a university professor and, among other things in his very complicated back-story, a leading expert on serial killers.
* ''{{Series/Luther}}'' involves a police officer named Luther working with Alice Morgan, a scientist and murderer who hid her crime so skillfully that not even Luther can prove her guilt.
* Everyone in ''{{Series/NCIS}}'' is very fond of their CloudCuckoolander lab techs, PerkyGoth Abby Sciuto and AbsentMindedProfessor Donald "Ducky" Mallard, who, rarely for a cop show, are markedly less combat-ready than their field agent co-workers. But still [[LetsGetDangerous no slouches]].
* Don and Charlie, the mathematician, from ''Series/{{Numb3rs}}''.
* ''Series/{{Perception}}'' had schizophrenic neuroscientist Dr. Daniel Pierce and FBIAgent Kate Moretti.
* ''Series/RizzoliAndIsles'', respectively.
* ''Series/{{Rosewood|2015}}'' is named for the scientist, private pathologist Baumont "Rosie" Rosewood, who consults with the East Miami PD in the person of Detective Annalise Villa.
* ''Series/RosemaryAndThyme'', two "gardening detectives." One is a former police officer and the other is a professor.
* In ''{{Series/The Sentinel}}'', a cop with SuperSenses works with an anthropologist who helps him understand his abilities.
* ''Series/TheXFiles'' is an early version of the trope, though it's not played as straight as other series. While Scully is an FBI agent, she was assigned to the X-Files division to lend scientific credibility (or not) to Mulder's paranormal investigations. She does engage in some normal agent tasks, such as interviewing suspects and making arrests, but her main contribution to the partnership is doing autopsies and running lab tests.

[[folder:New Media]]
* Repeatedly parodied in ''Dr. Boli's Celebrated Magazine'' with such fictional TV shows as "Harsh Words", where a by-the-book cop is partnered by a cold yet beautiful Forensic Etymologist.
[[/folder]]

[[folder:Webcomics]]
* ''Webcomic/ParadigmShift'' mixes this one with the traditional Buddy Cop routine. Mike and Kate are the standard ByTheBookCop and CowboyCop respectively, albeit downplayed significantly in Mike's case, but Gina the medical examiner is ByTheBook to the point of unreasonable at times. She also has the limited people skills part down pretty well, not that Kate doesn't also have her moments.
