->''"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 [[TheyFightCrime 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.

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.

* 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).
* 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/WildWildWest'' features Jim West (played by WillSmith) as the Cop while Artemis Gordon is the Scientist.
* Barrett Coldyron of ''Film/{{ROTOR}}''combines both roles in one character.

[[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.

[[folder:Live Action TV]]
* ''Series/RizzoliAndIsles'', respectively.
* Don and Charlie, the mathematician, from ''Series/{{Numb3rs}}''.
* ''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.
* 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).
* 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/{{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.
* 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]].
* 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/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.
* ''Series/{{Bones}}'' has Booth and Brennan, the cop and scientist respectively.
* ''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.
* ''Series/{{Fringe}}'' has the lovely [[ActionGirl Agent Dunham]] and CloudCuckoolander in residence Dr. Walter Bishop.
* For a [[Administrivia/TropesAreFlexible loose interpretation]] of the trope, ''{{Series/Castle}}'' is a novelist partnered with Detective Beckett (This arrangement 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.
* 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}}'' 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.
* the ''{{Franchise/CSI}}'' series all have elements of this. Jim Brass in the original ''{{Series/CSI NY}}'' borderlines this. The other members of the franchise focus more on the science, and ''Series/CSIMiami}}'s resident non-scientist is more supervisory, but in NY, Flack works alongside the scientist detectives under Mac, making the policework and science more equal and making it closer to this trope.[[/folder]]

[[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.
