!!Det. [=McCanna=] "Mac" Llewellyn Taylor
-->'''Portrayed by:''' Creator/GarySinise
-->'''Dubbed by:''' Creator/BernardGabay (European French)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/whitegold7.jpg]]

* AtonementDetective: Former Marine who still occasionally has flashbacks to the 1983 Beirut barracks bombing in which another man died in his arms. Tells one smug young perp, "I put men in the ground on foreign soil so you can sleep at night."
* ByTheBookCop: Tells someone he's about to fire for even considering compromising evidence:
--> [[RuleOfThree There are three things]] [[HeroicVow that I'll protect at any cost: the honor of this country, the safety of this city, and the integrity of this lab.]] As scientists, we have a great deal of power, the ability to assign guilt or innocence. But when we analyze a crime scene, we collect pieces of evidence, we make a promise to the people of this city. A promise to handle that evidence with respect, integrity, and good faith. When you broke this seal, you broke that promise.
* BadgesAndDogTags: Mac keeps several photos and mementos from his Marine days in his office at the Crime Lab.
* BondingThroughSharedEarbuds: "Indelible" has a touching flashback to Mac & Claire's last morning together where they share earbuds on the bus to work before he gets off at his stop.
* CharacterCatchphrase: If he has one, it's "My name is Mac Taylor," which, incidentally, is the title of the 100th episode, but he does not use it there; it's only uttered by *other* people with that name.
* ClearMyName: "Past Imperfect." A suicidal serial killer tried to frame him for the guy's own murder.
* CoolShades: Occasionally, such as in "Zoo York," he'll [[GlassesPull pull Horatio's trick]] with his own dark sunglasses.
* CowboyCop: Several times in season 3, especially going after a recently released serial killer without calling for back-up.
* {{Determinator}}: One VictimOfTheWeek is delivered to a laundry facility that handles linens from hotels all over the city. Flack snarkily comments that there are only about 70,000 hotel rooms in NYC. Our hero's response?
--> '''Mac:''' [[ILikeThoseOdds I'll take those odds.]] Ten minutes into the episode, the team has it narrowed down to the correct hotel.
* DigitalDeaging: CGI, lighting and sepia tones were used to make Sinise look 15-20 years younger in a flashback to Mac visiting his parents right before leaving the Marines to join the NYPD.
* EmbarrassingMiddleName: Mac ''Llewellyn'' Taylor. Stan, his former partner, had teased him about it relentlessly back in the day.
* EncyclopaedicKnowledge: Roller Derby rules, weaponry of all types, the ins and outs of dog show competitions, dentistry in other countries, buildings in other cities, space exploration, boxing...Mac's forever spouting some kind of information others don't expect him to know.
--> He and Sheldon are discussing the world of hip hop:
-->'''Mac:''' You should hear Aiden talk about this stuff. Close your eyes and she sounds just like Queen Latifa.
-->'''Sheldon:''' [surprised] What do you know about Queen Latifa?
-->'''Mac:''' [grinning slightly] It's my job to know a little something about everything.
* ExactWords: Mac is told not to utter the word "sniper" during a press conference in "Hide Sight." He doesn't, but verbally agrees with a reporter who does. Chief Carver asks what he's supposed to tell their superiors. Mac replies, "Tell them I never uttered the word 'sniper'."
* FamilyOfChoice: Mac regards his team as his family, and tells Christine so in 'Unwrapped.'
-->'''Mac:''' For a long time, this place, those guys, were my whole world. They helped me through some really tough times. And now I have you.
* AFatherToHisMen / BenevolentBoss: Tries his best to mentor Danny in Season 1 and comforts him when his brother is severely injured; inspires Lindsay with reenactments in Season 2, hugs her protectively on several occasions, during season 7 reassures her after her ordeal with Shane Casey in "The 34th Floor" and saves her from a hail of bullets in "Life Sentence;" saves Flack's life in the Season 2 finale; gives Sheldon a place to stay when he loses his apartment in "It Happened to Me;" helps Adam deal with issues stemming from his childhood in Season 9.
* FeetFirstIntroduction:
** It's actually in ''Series/CSIMiami's'' episode, "MIA/NYC Nonstop," but it's how Mac is initially seen as he exits a police cruiser upon arriving at the scene of the murder of the man Horatio first suspected of the killings in Miami.
** He gets a feet-first RE-introduction in season 8's "Keep It Real" upon returning to the crime lab after working at Piper Laboratories for a few months during his TenMinuteRetirement over the summer hiatus.
* FictionalFanRealCelebrity: Mac is a big fan of UsefulNotes/RonaldReagan. He keeps a framed 8" X 10" of the President in his office, and one co-worker teases him about "that 8-hour documentary you're always watching."
* TheFinickyOne: Danny tells Lindsay the word "joke" isn't in Mac's vocabulary, and Mac later tells a scheming reporter that he's a big fan of the rules.
* HeartbrokenBadass: Lost his wife, Claire, in the 9/11 attacks. Suffered with insomnia for years afterward.
* TheInsomniac: He doesn't like going home to an empty apartment. In the premiere, Stella asks Mac what time he came in to work; he says he never went home. In a later episode, she chides him about it, saying "You're never going to get any sleep in this lifetime, are you?" Once Jo takes over as second-in-command, she takes up the cause and even has Flack haul Mac out of a crime scene after he's been up for at least two, possibly three, days straight. Stella keeps on him about it too:
-->'''Stella:''' What do you do when you can't sleep?\\
'''Mac:''' Work.\\
'''Stella:''' No, what do ''normal people'' do when they can't sleep?
* ItIsNotYourTime: [[spoiler: Claire]] tells him so after [[spoiler: he's shot and nearly succumbs to his injuries in "Near Death."]]
* TheLostLenore: His late wife Claire, who died in the 9/11 terrorist attacks, and whom Mac is not only still mourning in the series premiere three years later, but is also not over her enough to fully commit to a new girlfriend two *more* years after that.
* ManlyTears:
** Averted with Claire. He doesn't cry when speaking about her to the locked-in victim or at Ground Zero in "Blink," or during his "limbo" period in "Near Death."
** Invoked with Christine. In "Misconceptions," he breaks down when he finally realizes that he's going to lose her if he doesn't swallow his pride, apologize for shutting her out, and open up to her.
* MarriedToTheJob: He doesn't even like to go home to sleep. Christine is helping him get his head out of work now.
* MysteriousPast: The series opens with Mac sitting alone in church at night. The audience isn't told what's bothering him until later in the episode, and details are slowly revealed as the season goes on.
* NamedAfterSomebodyFamous: Well, a famous fictitious character anyway. Sinise asked that his character's last name be changed to that of his most iconic film character, Lt. Dan Taylor from Film/ForrestGump.
* NearDeathExperience: When Mac is shot and critically wounded, he has an out-of-body experience where he converses with his colleagues and deceased wife.
* NoFullNameGiven: "Word of St. Paul" (Gary Sinise) says that Mac's full first name is [=McCanna=], but it's never used on screen. He's the one who asked Creator/AnthonyEZuiker to change it from Rick Carlucci to Mac Taylor to begin with, so that seems legit.
* OfficialCouple: First with Claire in a way, then Peyton in Season 3, and finally with Christine from mid-Season 8 through the series finale.
* OnlyKnownByTheirNickname: As explained on the Main and Trivia pages, Mac's given name is [=McCanna=].
* OOCIsSeriousBusiness: Mac tends to act as TheStoic most of the time, and is firm stickler for the rules and keeping a clear head. So when he is the one pissed beyond belief or flying off the handle, it's a sign of shit going wrong. Prime example being "Civilized Lies", where Mac is very angry and close to losing his temper numerous times when interrogating a suspect believed to have shot an off duty cop, to the point that, when Flack goes to interrogate the suspect and the latter asks if he's the "{{good cop|BadCop}}", Flack notes ''Mac'' is the one normally playing "good cop".
* PatrioticFervor: The first part of Mac's Heroic Vow is defending the honor of America. In "Can You Hear Me Now?" he is disgusted by a pair of victims having had [[IsNothingSacred sex on the Statue of Liberty's torch.]]
%%* PlatonicLifePartners: With Stella. Seems to be it with Jo since Stella left.
* RealMenCook: Claims to "make a mean cheeseburger" in the season 3 premiere. Prepares bruschetta for Christine in season 8.
* ScarsAreForever: Mac has scars from being burned by a hot piece of shrapnel during the 1983 terrorist bombings in Beirut, from being blown up in "Charge of This Post," and from his bullet wound in "Near Death."
* SemperFi: Once a Marine, always a Marine. Note his use of the present tense in this exchange from "Tanglewood" in Season 1:
-->'''Sonny Sassone:''' That's right. That's the way we do it. Mafia style. You look a man dead in the eye and watch the light go out. But chu wouldn't know anything 'bout *that* would ya, *coppa*?
-->'''Det. Mac Taylor:''' ''I'm a Marine,'' you little punk. I've put men in the ground on foreign soil so you can sleep at night, but you wouldn't know anything about *that*, would ya - *kid*?
* SharpDressedMan: He wears a suit to work more often than not (complete with tie in season 1). Even when his suitcase goes missing for weeks upon his return from London in season 4, he still manages to dress nicely. The black button-down shirt he dons before his suitcase is returned is so sharp Danny remarks, "Whoa, Mac, back in black!"
* SingleEpisodeHandicap: He's stuck at home with his leg propped up, a sprained right arm, and a few broken ribs for most of "Point of View." He's completely healed by "Vacation Getaway."
* StandardCopBackstory: Military career, deceased spouse, little to no personal life, and an argument can be made that he inadvertently caused the death of a childhood friend's older brother by not shooting the guy who was beating the boy to a pulp when he had the chance (at age 14).
* TheStoic: Sinise himself once said of his character, "He smiles once a season."
* TeamDad: Whenever the others, especially Adam, are goofing around in the lab, he always sets them straight. Usually a stern look will do the trick, but occasionally such as the time Adam & Danny where teasing Lindsay by using age progression software on a pic of her, he'll say something parental like, "Are you three done?" and they'll immediately snap to attention. [[PapaWolf But let anyone else threaten any of them...]]
* TenMinuteRetirement: Although he leaves the Lab over the 2011 summer hiatus, he returns as Lab Chief the second episode of the next season.
* TwoFirstNames: Mac Taylor.
* UnprocessedResignation: Sinclair pulls Mac's retirement papers when he asks to return to the Lab after his 4-month stint at Piper Laboratories at the beginning of season 8.

* PutOnABus: At the beginning of season 7. She transfers to New Orleans to head up the crime lab there and is never seen nor heard from again after episode 7.01 (and only because she sent Lindsay a package then). There is one mention a short time later, tho; Lindsay refers to "the last case Stella was working on" in a conversation with Jo.

* BeardOfSorrow: Is revealed to have grown one in the season 6 opener [[spoiler:due to having been paralyzed from being shot in the season 5 finale.]]

[[folder:Lindsay "Montana" Messer]]
!!Det. Lindsay "Montana" Messer (formerly Monroe)
-->'''Portrayed by:''' Creator/AnnaBelknap
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/6513924_orig.jpg]]

* ActionMom: Saving Lucy from [[spoiler: Shane Casey.]]
* BewareTheNiceOnes: She's sweet enough, until someone threatens her family.
* BigEater: In "Food for Thought":
--> '''Lindsay''': *''gives Danny a LongList of food to pick up''*
--> '''Danny''': *''scoffs, starts to walk off, turns and gives her [[OhCrap a look]]''*
--> '''Lindsay:''' I'm not [[WackyCravings pregnant]], I'm just hungry.
* BrainyBrunette: It was her analysis of blood spatter in a major case in Montana that caused Mac to hire her in the first place. Inspired by his demonstrations in "Zoo York" and a few other episodes, she becomes a reenactment expert. In one of her earliest episodes, she answers a question of Mac's before he has a chance to ask it. He asks how she knew what he wanted and she explains her thought process, which impresses him. In "The Lady in the Lake," she asks Mac if he believes in luck, then goes into detail as to how she arrived at a conclusion which provided a lead in the case. Mac tells her, "That's brains, not luck."
* DarkAndTroubledPast: Lindsay survived a massacre back in Montana. It scarred her so much that she has trouble talking to mothers whose children are murder victims, and even rushes out of one crime scene that reminds her too much of the incident.
* ExpositoryHairstyleChange: Sports mid-length hair in seasons 2 & 3, either straight or wavy before having chin length hair from season 4-6, then to shoulder length hair from season 7-9.

* HappilyMarried: To Danny, beginning in late season 5.

* HometownNickname: She's from Bozeman, MT.
* MamaBear: Not a good idea to mess with Danny and Lucy.
* MysteriousPast: Her big secret was hinted at a while before it was finally revealed [[spoiler: she survived a shooting.]]
* OfficialCouple: With Danny.
* ScreamingBirth: Screams while in labor when Lucy is born near the end of "Greater Good."
* SoleSurvivor: The only reason she wasn't killed along with her friends is because she happened to be in the ladies' room when the perp arrived.
* StandardCopBackstory: She survived a mass shooting as a teen that claimed the lives of several of her close friends and is still traumatized by it as an adult.
* SurvivorsGuilt: She's been dealing with this ever since, due to the above. Finally resolved when she successfully testifies against the killer, resulting in him being sent to Death Row and executed.
* TraumaButton: Lindsay has trouble in early appearances when the VictimOfTheWeek is a teenage girl, as the sight of their bodies often causes flashbacks to the murder of her own friends when they were teens.
* WrittenInAbsence: Lindsay does not appear in a few episodes of both season 3 and season 5. Anna Belknap was on maternity leave both times.

[[folder:Don Flack]]
!!Det. Donald Flack, Jr.
-->'''Portrayed by:''' Creator/EddieCahill
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/don_0.png]]

* BrokenPedestal: His mentor, Moran, turned out to be dirty.
* CopAndScientist: Flack works closely with either Mac, Stella, Danny, Lindsay, Jo or some combination thereof on just about every single episode.

* VigilanteExecution: He [[spoiler:shot Angell's killer in cold blood]].

[[folder:Sheldon Hawkes]]
!!Dr. Sheldon Hawkes
-->'''Portrayed by:''' Creator/HillHarper
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/commandp4.jpg]]

From CBS's original character bio: "Raised in Harlem, Dr. Hawkes was a child prodigy who graduated college at eighteen. By twenty-four, he was a board-licensed surgeon. Because he was young and socially inexperienced, however, his education could not shield him from the pressure of having to save lives. Two years later, Dr. Hawkes left the operating room, retreating to the safety of the medical examiner's office."

* BewareTheNiceOnes: Sheldon doesn't lose his temper often, which makes the moments where he does all the more incredible. A memorable example is the episode "Hammer Down," in which Sheldon delivers a [[TheReasonYouSuckSpeech vicious tirade]] to a doctor who was part of a human trafficking network. Given that Sheldon was not only a doctor but had also recently lost his savings because of a scam artist, Sheldon's anger at the man for taking advantage of people's trust was very understandable.
* BlackAndNerdy: See character bio quote above.
* ClearMyName: Framed for robbery and murder in "Raising Shane."
* HeroDoesPublicService: Volunteers at a clinic and as a medic in Central Park on his days off.
* TheMedic: In addition to his volunteer duties, Sheldon serves as the team's go-to medical professional. Mac once asked him to stay outside while he and the other officers chase a heavily armed gang into a building because he expects casualties needing immediate medical attention. Sheldon replies, "Then this is where I'll be." In another episode, he tends to Sid before the ambulance arrives when the M.E. is exposed to radiation.
* NotThatKindOfDoctor: Averted. In "Corporate Warriors," a suspect asks him, "What kind of doctor investigates fires?" Sheldon had spent five years in the ER before transferring to the morgue, then to the Crime Lab.
* StandardCopBackstory: His sister was murdered, and a girlfriend was raped and he failed to be there when she needed him. He doesn't talk about either one of them much at all.
* ThereShouldBeALaw: Sheldon is particularly disturbed by the fact that stalkers get away with terrorizing their victims because the things they do (phone calls, taking pictures, etc.) aren't illegal on their own.
[[/folder]]

[[folder:Sid Hammerback]]
!!Dr. Sid Hammerback
-->'''Portrayed by:''' Creator/RobertJoy
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/sid_hammerback.jpg]]

* AnonymousBenefactor: The newspapers dubbed him "The Guardian Angel" for his $1 Million gifts to families of ten victims whose cases had really stuck with him.
* TheCoroner: Obviously. Took over a few episodes after Sheldon transferred to the field.
* CreepyMortician: Sid's Creepy Place.
* IronButtmonkey: Endures quite a bit for the amount of screen time he has: goes into anaphylactic shock from an unnamed sandwich ingredient, gets radiation poisoning from a corpse, learns a trusted ex-colleague turned criminal, narrowly avoids being blinded by an explosive bullet, and finally makes millions on an invention...only to be diagnosed with cancer.
* NonIdleRich: Continues to work in the morgue after making his fortune.
* RagsToRiches: He wasn't exactly poor before, but he wasn't wealthy either. Now he's made a bundle on his pillow invention.
* SecretlyDying: He revealed to Jo that he has advanced Non-Hodgkin's Lymphoma. WordOfGod says he will not die onscreen, but it's indicated he's heading for an end.
* SecretlyWealthy: Though that may be changing now, since anyone who isn't Jo, and possibly Mac (who may or may not know due to being his beta tester for the pillow, and who mentions Sid's fortune while "in limbo"), has to notice the piano in the morgue. [[note]]Until it conveniently disappears.[[/note]]
* SpecsOfAwesome: They're what keep him from being blinded, if not killed, by the exploding bullet he extracts from a victim's head.
* SupremeChef: Mentions recipes he's tried, often with fairly exotic ingredients. Tells Mac in "Food for Thought" that he went to culinary school in France.
* TooMuchInformation: Likes to overshare at times. In "Stealing Home," which involved a "committed threesome" who had incorporated yet another person into their lifestyle, Sid starts telling Sheldon about a three-way he'd had back in college.
-->'''Sheldon:''' Sid. [''Sid keeps talking.''] Sid, I-I gotta go. [''Walks away leaving Sid looking disappointed that he didn't get to finish his story.'']

[[folder:Adam Ross]]
!!Adam Ross
-->'''Portrayed by:''' Creator/AJBuckley
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/ross_5.jpg]]

* AbusiveParents: In "Some Buried Bones," Adam tells some of the team that his dad is a bully. In "The Real [=McCoy=]," he reveals to Mac that the man had been physically abusive to both him and his mother, and that his older brother had left home because of it.
* ButtMonkey: Adam tends to get picked on a lot by the rest of the team for his dorky behavior, Mac and Lindsay in particular always seeming to enjoy busting his balls. They make clear though it's all in jest, and that Adam is [[EveryonesBabySister like a brother]] to them.
* {{Catchphrase}}: "What up?!"
* TheDutifulSon: Adam's only sibling had left home before Adam graduated high school and is implied to have never returned, leaving Adam to deal with their father once the man is institutionalized with Alzheimer's. Since the family is from Arizona and Mr. Ross is now in NYC implies that he'd had the man moved cross-country so he could help look after him.
* HonorThyAbuser: Adam still visits his father in hopes of connecting with and eventually developing feelings for the man, in spite of having been beaten by him as a youngster.
* HonorThyParent: In explaining to Mac why he still visits his father, Adam says, "Aren't you supposed to honor your parents?"
* TheLabRat: Adam bounces around between DNA, Trace, Audio-Visual, and eventually Ballistics.
* SadClown: Adam jokes around a lot at work, possibly as a coping mechanism for the issues with his father.
* SleptThroughTheApocalypse: Partied with some college buddies the night of Sept 10, 2001 and didn't wake up till the following afternoon. "And by then, the entire world had changed."
* StandardCopBackstory: Physically and verbally abused by his father, who now has Alzheimer's so can't acknowledge his responsibility.
* TechnoWizard: Once he's joined the team, virtually all the A/V and computer-related investigations become his responsibility, as opposed to Danny's prior to his arrival.

[[folder:Jo Danville]]
!!Det. Josephine Danville
-->'''Portrayed by:''' Creator/SelaWard
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/whitegold3.jpg]]

* AmicableExes: Her ex-husband still works with the FBI and pops up from time to time.
* AloneWithThePsycho: "Means to an End."
* ByTheBookCop: Much like Mac, Jo places heavy value on following protocol and adhering to a set of ethics that preserves the integrity of the investigation. This screwed things up for her though in the case against John Curtis while she was with the FBI. After her coworker Frank Waters mislabeled the DNA sample and tried to cover it up, she reported him herself and then fired him, tanking the case and letting Curtis walk free due to lack of evidence. ''[[ZigZaggedTrope Unlike]]'' Mac though, she doesn't always practice what she preaches. When John Curtis is accused of another rape, Frank [[WhatTheHellHero calls her out]] for refusing to let it go, and numerous characters point out how she's ''not'' supposed to be on his case if he strikes again due to conflict of interest, with Jo refusing to listen because ItsPersonal for her.
* BrainyBrunette: Profiles victims and suspects so correctly it surprises them...as well as her colleagues.
* TheConfidant: For Sid. First, when he sells his pillow patent for $27 Million, he asks her not to tell anyone. Later, when she finds out that he's the so-called "Guardian Angel" secretly giving million-dollar checks to seemingly random people, he asks her to keep his name out of it. Finally, after he's diagnosed with cancer he asks her to be his confidant yet again... and to let him decide when the time is right for him to step down from his position as Medical Examiner. She agrees every time.
* FBIAgent: Formerly.
* IWantGrandkids: Played with. She's after Mac, not her kids, to start a family.
** Episode 7.18, "Identity Crisis," ends with this exchange:
--->'''Jo:''' Mac, you need to get married and have kids, so I don't have to go through all these challenges alone.
--->'''Mac:''' Have you lost your mind?
--->'''Jo:''' Yeah, don't get married. Just adopt a child. Children are wonderful.
--->'''Mac:''' Misery loves company, huh?
--->'''Jo:''' You would make a great father.
--->'''Mac:''' Jo. Stop.
--->'''Jo:''' Don't you ever think about being a grandfather?
--->'''Mac:''' [scoffs] Hey, if I buy you a burger and a beer, will you stop talking?
** See second example under The Matchmaker also.
* TheMatchmaker:
** Discussed. During Mac's "Near Death" experience in the season 8 finale, he and Sheldon take turns telling each other that they should get married. Each responds with a variation of "You sound like Jo."
** In season 9, Jo tells Mac that he and Christine need to get married and "start plopping little blonde babies out into the world." He raises his eyebrows and she says, "I see the way you two look at each other." He gives a slight eyeroll, turns and walks away without a word.
* TheProfiler:
** Part of her training with the FBI, and she's very good at it. Makes a great first impression on Mac by profiling the victim upon her arrival at the lab in episode 7.01, "The 34th Floor."
--->'''Mac:''' (''wide-eyed'') Do you happen to know her mother's maiden name?
** In episode 8.10, "Clean Sweep," she uses her skills to help a somewhat shell-shocked suspect remember exactly what happened.
* SouthernFriedGenius: An expert profiler/scientist from Alabama who tells Mac that people, be they suspects or superior officers, open up to her because they don't quite know what to do with her Southern charm. Maybe it's the accent.
* StandardCopBackstory: Divorced. Sister was killed by a drunk driver.
* SweetHomeAlabama: Jo is from Alabama and still plugs her alma mater ("Roll Tide!") when meeting folks from her home state. She tells Mac that New Yorkers don't know what to do with her Southern charm so they open up and tell her things they wouldn't otherwise reveal. It helps her get information out of both suspects and superior officers.
* TeamMom: Kinda takes over the role from Stella, especially with Adam after he witnesses a death via the internet in "Unfriendly Chat."
