Characters: Blue Bloods

    open/close all folders 

The Reagan Family

  • Action Girl: The Reagan women do get kidnapped from time to time but they never go down without a fight.
  • Always Gets His Man: A family variant. No matter who they're up against, they always get the bad guy.
  • Badass Family: Great-grandpa Henry's response to one of Danny's kids asking if a robber would target them says it all:
    Henry: Are you kiddin'? He'd get one look at this table and run the other way.
  • Drives Like Crazy: After Nicky bails from having Erin teach her to drive because she can't deal with her mom's, erm, style, Frank points out that almost every member of the family is bad at driving: Henry gave up the keys after smacking his fender on the garage too many times, Erin rages at other drivers and leans on the horn, and Danny apparently once got a ticket for doing 80 in a 25. Except "the patient one, Jamie," who eventually gets the job of Nicky's driving coach.
  • Four Philosophy Ensemble: Danny is the Cynic, Erin is the Idealist, Frank is the Realist, Jamie and Nicky are The Conflicted.
  • Officer O'Hara: Averted mostly, but they are Irish-Americans.
  • Real Men Love Jesus: Everyone of them has a revered love of Christ.
  • Red Oni, Blue Oni: Lampshaded by Henry who claims all his maternal line are stoics and all the paternal line Hot-Blooded.
  • Semper Fi: Henry, Frank and Danny are all marine corps veterans from Korea, Vietnam and Iraq respectively.

    Frank Reagan, New York City Police Commissioner 
Played by Tom Selleck

Head of the Reagan family and the NYPD. A stern but fair man, Frank Reagan often has to deal with the complexities and
  • Action Dad: He may be the police commissioner, but he was still a member of New York's Finest and is not averse to getting his hands dirty.
  • Always Gets His Man: Oh yes. If you've done wrong on his watch he will find a way to get you, and he'll do it by the book. If by some miracle the guilty party manages to slip out of getting caught, Frank is a patient man. The next time they slip up, he'll be waiting for them.
  • Badass Grandpa: A grandfather of three and someone not to underestimate.
  • Badass in a Nice Suit: Invariably wears very snazzy three-piece suits while at work, and once kills a man for putting a gun to Erin's head while wearing it.
  • Badass Mustache: Wouldn't be a Tom Selleck role without it.
  • Berserk Button: Frank loathes Dirty Cops. He considers them a disgrace to good police in general and the NYPD in particular, and then a group of them made it personal by murdering his son. What's notable is how low-key he is about it. He doesn't raise his voice and his expression barely changes even though it's abundantly clear how furious he is. When he confronted the ones responsible at the end of the first season, it's almost terrifying how calm he looks during the entire exchange. He only loses his cool for a moment when he knocks some things off the top of a cabinet, which is also one of the few times he raises his voice. He's not shouting either, he raises it the way people do when they want to make sure they're heard.
  • Beware the Nice Ones: Do NOT hurt a member of his family. He'll put you down without a word.
  • By-the-Book Cop: Firmly believes that the rules are there for a good reason, and stresses that a cop who follows them will do more good than by ignoring them. There are several occasions where he's seen reviewing methods and procedures with his lieutenants to see what's working and what isn't. The book is there to help officers do their jobs correctly, and if something new will help with that then he makes sure it gets added.
  • Can't Take Criticism: His main fault: Frank gets all defensive when anyone from from City Hall dares to criticize his department. It's one of the reasons why he's unpopular there, with the exception of Mayor Poole.
  • Change the Uncomfortable Subject: Virtually every time a family-dinner argument reaches the point where he's asked to take sides, Frank opts out of doing so by complimenting the food or asking someone to pass him a dish.
  • Cool Shades
  • Create Your Own Villain: He admits to Danny that the NYPD's inaction against Rev. Potter is partly why the man is so dangerous.
  • Da Chief: One of the best you'll see on television, no less. Frank Reagan is the kind of authority figure that people wish was more common.
  • Dead Partner: As a young cop, Frank worked with the NYPD's canine unit until his dog was killed by the criminal he'd sent her after. When another canine officer is accused of biting a child, Frank makes a special effort to exonerate the dog, and Henry suggests Frank does so to make it up to his fallen animal partner.
  • A Father to His Men: Cares deeply about the NYPD and his children.
  • Four-Star Badass
  • The Good Chancellor: A commissioner variant. Frank Reagan is one of the best.
  • Good Is Not Soft: He's personally killed at least one villain, and in the season five finale he uses a little Loophole Abuse to send an already-convicted Gang Banger to federal death row, which has the dual effects of removing his ability to control his gang from inside the joint (since he'll be transferred to Indiana for trial), and exacting justice for the murder of a police chief, his wife, and a witness, and the nonfatal shooting of Linda.
  • Guile Hero: Has run gambits on criminals before, as well as once maneuvering a diplomat whose son was a rapist into unintentionally giving him a DNA sample. His PR guy says he should run for mayor, because though he states he hates politics, he is very good at it.
  • Hero Does Public Service: When Mayor Poole takes office, he reveals to Frank Reagan that he wants to keep him on as police commissioner partly because, back when he was a kid, there was this white Irish beat cop who coached his basketball team.
  • Hero with Bad Publicity: Thanks to Rev. Potter's constant hate-mongering half of New York City is convinced that Frank is some sort of fascist dictator. As a whole, Frank is continually frustrated that cops as a whole don't get respect anymore from either average citizens or their fellow city officials. He was really furious at having to answer to a court appointed Inspector General in Season 4.
  • Idiot Ball: Despite all the blatant illegal things Rev. Potter does, Frank never presses to have him arrested which just gives Potter the freedom to continue his witch hunt against the Reagan Family and NYCPD.
  • It's All My Fault: As Henry explains, he tends to blame himself if something goes wrong.
  • Like Father, Like Son: Despite being able to adapt with the times, their scenes together show that Frank is very close to Henry.
  • Manly Tears: Not actually seen, but heavily implied during a private moment. When his old partner dies from respiratory disease caused by exposure to toxic fumes on 9/11, the episode ends with Frank visiting the 9/11 Memorial (the first time it ever appeared in a TV show) by himself, and standing with his back to the camera, placing his hand on his friend's engraved name on the memorial: we purposely can't see his face, but his stance and the way his shoulders are moving clearly imply that Frank is crying.
  • Nice Guy: Frank is the thoughtful one of the family and is always willing to stop disputes if they arise at Sunday dinners.
  • Papa Wolf: To his family, naturally, and to the men and women of the New York Police Department. Perfectly summed up in a speech where he tells the NYPD rank-and-file, including Jamie and Danny, "I will ALWAYS have your back." He himself is backed up by his own Papa Wolf, Henry.
  • Parental Substitute: Acted as the closest father figure to his only granddaughter, Nicky, since her biological (and still alive) father was a deadbeat.
  • The Patriarch: The head figure of the Reagan family.
  • Poor Communication Kills: He's never able to effectively counter all the bad publicity that police get, and when coupled with Rev. Potter's hate-mongering means that by Season 6 his reputation is in shambles. It's so bad that Mayor Poole is actually reluctant to keep Frank as PC because he's a political liability.
  • Reasonable Authority Figure: Out of all the family members, you can usually count on Frank to be the one most likely to see and understand both sides of a debate. He's usually quite excellent at weighing both sides, and coming to a reasonable solution, and despite his pride, he's not shy about admitting when he himself makes a mistake. Some have compared him to an idealized Roman magistrate. Many have noted that he's the type of authority figure that people wish was more common.
  • Revolvers Are Just Better: Frank continues to carry his old snubnose .38 Special revolver, despite his father telling him he should switch to a semiautomatic for more firepower. In one scene, Frank demonstrated he doesn't need to.
  • Semper Fi: Was a Marine in Vietnam.
  • Shell-Shocked Veteran: Became The Stoic due to this, having seen many terrible things in the line of duty and bottling it up to keep from spilling over onto his family.
  • The Stoic: But it doesn't mean he's heartless. In one episode, he admits to his granddaughter Nicki that he has decades worth of tragedies he's seen and experienced, and instead of showing these emotions, "I sit on them." Occasionally, and mostly in private, these emotions do come out. When his old partner dies from respiratory disease caused by exposure to toxic fumes on 9/11, the episode ends with Frank visiting the 9/11 Memorial (the first time it ever appeared in a TV show) by himself, and standing with his back to the camera, placing his hand on his friend's engraved name on the memorial: we purposely can't see his face, but his stance and the way his shoulders are moving clearly imply that Frank is crying.
  • Survivor's Guilt: In "The Job" Frank admits to feeling some over the fact that some of his other former cop friends became ill from chemical exposure experienced during and 9/11.
    "Why them and not me?"
  • To Be Lawful or Good: A recurring plot is Frank being forced to choose between his legal responsibilities as police commissioner and his desire to do what is morally right. He's extremely good at finding the third option that allows him to do both.
  • What Would X Do?: His go-to when it comes up is "What would Theodore Roosevelt do?"

    Henry Reagan 
Played by Len Cariou

Great-grandpa of the Reagan family. Was a hardbitten Da Chief in his day; now dispenses wisdom and advice.
  • Badass Grandpa: Oh yeah. When Frank is shot, he's the one sitting in the hallway, up all night alert, ready to protect his family. Not to mention an episode where Henry, while withdrawing cash from an ATM, is attacked by a mugger: Henry is not letting this happen without a fight, and defends himself with a pistol hidden in his ankle holster. When the criminal struggles to prevent him from reaching it, Henry then resorts to Good Old Fisticuffs.
  • Cool Old Guy: Is this to his grandchildren and great-grandchildren. Also, due to being an honest cop and not taking any shit, has the eternal respect of the NYPD rank and file. He's also lost absolutely none of his toughness since his days as a cop.
  • Cowboy Cop: Henry seems to indicate that he was a Cowboy Cop in his time. Of course back then there was more "flexibility" in what was allowed anyway. At one point, he is caught on video mouthing off (while drunk) to an old buddy about how he'd like to reintroduce some very heavy-handed tactics, resulting in a public controversy that causes both Frank and DCPI Garrett Moore to give him a What the Hell, Hero? speech, much to his chagrin.
  • Da Chief: Henry is a former police commissioner, detective, and officer, who was known for being incorruptible.
  • Drives Like Crazy: Mostly because he's in his eighties and his eyesight isn't what it used to be. One subplot has him arguing with Frank about giving up the keys after he banged the fender on the garage door for (apparently) the umpteenth time. In the end he gives his car to Danny and Linda because their minivan caught fire due to an electrical fault earlier in the episode.
  • Everybody Has Standards: While Henry believes in the "cops should be loyal to cops" philosophy, he will not honor a cop that had two families a the same time.
  • Glory Days: Sometimes longs for the days when life was simpler and you could be a cowboy cop.
  • Good Old Ways: Generally tends to be older fashioned, but with one subversion: he advises Frank to switch to an automatic instead of a revolver, for more firepower. In general, Henry tends to prefer the older Cowboy Cop methods from back in the day, which often causes him to clash with Frank and Jamie (though it definitely endears him to Danny). In one episode he refers to this trope almost word for word: in response to being chastised by Frank and Garrett for most of the episode (because of his bragging about heavy-handed methods from the old days), he responds by growling "I still think the old ways are the best ways."
  • Hollywood Heart Attack: Poor Henry is hit with one on Thanksgiving.
  • Mysterious Past: We know he served in Korea, but he apparently doesn't like to talk about it.
  • Noble Bigot with a Badge: A rare example where the person is someone who is a former officer. He has some conservative views on gay individuals, but doesn't harbor any actual malice.
  • Papa Wolf: When Frank is shot, he's the one sitting up the whole night with his hand by his gun, guarding his family. In other words, he's the Papa Wolf to the Papa Wolf! Do NOT mess with the Reagan family, a Badass Family protected by two suitably badass father figures.
  • Semper Fi: Was a Marine in Korea. A throwaway line implies he may have been in the Pacific theater of WWII as well.
  • War Is Hell: He's proud of his military service, but his reluctance to go into detail about his war experiences indicates that he probably saw a lot of things that still haunt him. The same may be true of some of his experiences as a police officer.
  • When I Was Your Age: Often gives the younger family members anecdotes and advice based on his experience.

    Danny Reagan 
Played by Donnie Wahlberg

Ambiguously the eldest of the Reagan siblingsnote , Danny is a police detective assigned to Manhattan. He is Happily Married and has two sons.
  • Action Dad: A cop detective and father of two.
  • Aloof Big Brother: Isn't very close to Jamie, due to their age differences.
  • Always Gets His Man: Danny has one of the highest case closure rates of any NYPD detective.
  • Badass: Like all the Reagans he's no pushover. He was also the winner of a NYPD/FDNY boxing tournament two years in a row.
  • Berserk Button: Danny has a lot of them. So take notes.
    • Don't hurt his family.
    • Don't hurt his partners.
    • Don't kill a cop.
    • Don't kill someone from the Marines.
    • Don't say "America should just forget about 9/11".
    • Don't hurt a child.
  • Big Brother Bully: Downplayed. Danny makes insensitive remarks towards Jamie, but it's more of a way to prepare his little brother to the dangerous streets.
  • Big Brother Instinct: An asshole he may be to Jamie at time, there's no denying that Danny won't hurt someone who threatens his little brother. The same goes with Erin, although it's yet to be revealed if he's older or younger.
  • Big Brother Mentor: Any opportunity he has to teach Jamie, he'll do it.
  • Chick Magnet: Implied. Danny apparently had a lot of girlfriends before he married Linda.
  • Cowboy Cop: He bends the rules in pursuit of justice. Although he's also been known to bend them the other direction (i.e. coaching an illegal immigrant on how to frame his confession to manslaughter for sympathy). Deconstructed in "Absolute Power". Danny goes in solo after a Serial Killer instead of waiting for Baez and ESU. While he rescues the would-be victim, the killer puts him in the hospital with a broken forearm and gets away.
  • The Cynic: Danny has a sour perspective in general, especially towards criminals.
  • Deadpan Snarker: Always ready with the quips.
  • Fatal Flaw: Danny's inability to control his temper has strained his relationships with his family (to the point he got in a fight with Jamie) and has gotten several reprimands because of it.
  • Fighting Irish: He's from an Irish-American family and has a history as a Marine, a Cowboy Cop and a highly-competitive amateur sportsman.
  • First-Person Smartass: Danny will snark anyone — His family, his partners, other cops/detectives, or civilians.
  • Friend to All Children: As tough as he is with grown-ups, he's actually quite tender when talking with youngsters, to the point where at times he's the "good cop" instead of Jackie.
  • Generation Xerox: Shares Grandpa Henry's preference for Cowboy Cop methods. Also, he, Jamie, Joe, and Frank all followed in Henry's footsteps in becoming cops (even if Danny's the only one who shares Henry's belief in the Cowboy Cop methods).
  • Good Is Not Nice: He is an honest cop, a skilled detective, and a devoted family man. He's also fond of screaming at and insulting suspects and isn't above using the Jack Bauer Interrogation Technique on occasion. In addition, he makes some borderline Islamophobic remarks in "Worst Case Scenario" (and is called out for it by his partner Maria Baez).
  • Guile Hero: Although subtlety doesn't seem like his strong suit, he can run a game on the bad guys when he puts his mind to it.
  • Happily Married: To his wife, Linda.
  • Hot-Blooded: His temper is very well-known around the NYPD and landed him in anger management therapy at one point. He channels it into his job and tries very hard to avoid bringing it home; he doesn't always succeed.
  • Hypocrite: Danny has no problem committing acts that go beyond the rules (though he's not a Dirty Cop). However, if another cop does the same thing he did, he'll call them out on it.
  • It's All About Me: Danny has a rather selfish attitude when it comes to solving his cases. For example, in "Ends and Means", he remained very upset with Linda throughout the episode for not letting him talk to an informant (who later died), even though Linda could've been in trouble had she done so.
  • Jack Bauer Interrogation Technique: Not often, but on occasion. He waterboards a Serial Killer in the first episode for information. Although he does tend to bend the rules, this is the only time he uses torture in the entire first season, but the quickness with which he uses it in the pilot seems to imply this is a semi-regular thing for him. In a season four episode he beats information out of a heroin dealer whose accidentally uncut load of dope caused several fatal overdoses (and then uses him as a Human Shield), which suggests the takeaway is that he's not above torture when he views the situation to be serious enough.
  • Jerkass Fašade: Generally behaves like a jerk towards his youngest brother Jamie; Frank explains to Jaime that it's because Danny can't bear the thought of losing another brother, so he tries to Stealth Mentor him.
  • Jerk with a Heart of Gold: Danny is abrasive, rude, and can be a real jerk. Despite all that, he's still a good and fair cop, as well as someone who deeply treasures his family.
  • Karma Houdini: Downplayed. Danny has never committed an outright heinous act and is by no means a Dirty Cop. However, he has done many acts that are considered violations of protocol and the rights of a suspect; things that could get him fired in real life.
  • Knight in Sour Armor: Generally sour towards the world in general, but gets up every morning to make New York a better place because he loves this city.
  • Man Child: Downplayed. Danny is mature, but often the most immature of his siblings and refuses to let go of a topic if it personally offended him.
  • Married to the Job: Much to his actual wife Linda's chagrin, and often a source of tension when Danny has to leave his family's side to go out on a mission.
  • Nice Hat: Danny is often seen wearing a greyish-black cap.
  • Noble Bigot with a Badge: Danny made some borderline Islamophobic remarks in "Worst Case Scenario", but doesn't harbor any actual hatred.
  • The Not-Love Interest: To his partner Jackie. During the rare instances where she and his wife Linda are onscreen at the same time, it's quite clear Linda has no problem with her.
  • Papa Wolf: As noted above, anyone coming near his family is pretty much leaning on his Berserk Button.
  • Pay Evil unto Evil: His general MO. He can be absolutely vicious in the pursuit of justice (like when he beat a confession out of a child predator) and gets called on it on occasion by fellow cops and his more level-headed siblings.
  • Red Oni: Again, to his partner Jackie.
  • Semper Fi: Served as a Marine in Iraq — specifically Fallujah.
  • Sole Survivor: He was the only member of his Marine unit in Iraq to make it back home.
  • The Southpaw: Because Donnie Wahlberg is a lefty.
  • Tough Love: Deconstructed with Jamie — Danny puts on a Jerkass Fašade to his brother because he wants him to know everything he needs to know. However, this (unsurprisingly) causes Jamie to resent his brother for "tearing me [him] down every chance" and only adds more tension to their already distant relationship.
  • Weapon of Choice: In keeping with his maverick attitude, he carries a noticeably different, silver pistol rather than the black Glocks used by the rest of the NYPD cast (other than Frank's ancient Fitz Special). IMFDB identifies it as a Smith & Wesson 5946, a pragmatic choice by the props department considering that the weapon, though not standard issue, is still allowed by NYPD regs in real life.
  • When You Coming Home, Dad?: Danny's sons have never complained on-screen about his absence, but his siblings and wife have called him out on not spending time with his kids. At least one episode indicates he schedules himself for a lot of extra tours because he and Linda are having money problems (which makes sense: they're supporting two kids and a mortgage as a police detective and a nurse, neither of which pays well).

    Joe Reagan 

The middle Reagan brother. Killed in the line of duty before the show starts, a running arc in the first season is Jamie investigating his death.

    Jamison "Jamie" Reagan 
Played by Will Estes

The youngest of Frank Reagan's surviving children, and a rookie cop at the start of the series. A Harvard Law graduate, he changed his mind about being a lawyer and joined the NYPD partly because of his dead brother Joe, and partly because he wanted to help people more than he wanted to make money.
  • All-Loving Hero: Jamie is always looking out for those he thinks need help and tries to sympathize with criminals.
  • All of the Other Reindeer: Downplayed. Jamie isn't actively ostracized by his cop peers, but many of them think he's an Entitled Bastard because he's the police commissioner's son and will often accuse him as such.
  • Amazon Chaser: Jamie has a thing for opinionated, strong women.
  • The Baby Of The Bunch: Like it stated earlier, Jamie is the youngest of Frank's children.
  • Berserk Button: Jamie will lose his normally cool and level-headed exterior if someone hurts the ones he loves. Sgt. Renzulli notes that Jamie's absolute ferocity when a criminal attacks Eddie implies that Jamie loves her; he's right.
  • Beware the Nice Ones: Jamie is much more even-tempered than Danny and tends to have better people skills, but when he does lose his temper? Whoo, boy. In one episode he goes for a tour with a cop who turned in her partner for killing a suspect with an illegal choke-hold (because she's being shunned for snitching). After Eddie and her current ride-along have to drive halfway across the patrol area to back them up in a shootout (because nobody else responded to the snitch's call for backup), he lets every cop in the precinct have it with both barrels.
  • Break the Cutie: His biggest ones were as followed:
    • Being tricked into a Suicide by Cop.
    • His partner, Vinny, being gunned down and witnessing his death.
  • By-the-Book Cop: Very much so; this is part of the tension between him and Danny.
  • Character Development: Undergoes the most of any of the main characters, with a years-long arc tracking his development from New Meat into a seasoned beat cop bucking for detective.
  • Chick Magnet: Put Jamie in the same room with almost any woman his age (minus Erin, naturally) and she'll be cooing over him before long.
    • He starts the series with Sydney, later attracts Laura (a witness he had to guard), then attracts Bianca, a Mafia Princess.
    • If Erin can be believed, he sets all the female paralegals in the DA's office a-twitter as well.
    • A deleted scene says that he was the source of much gossip among his female classmates at the academy. He doesn't seem to capitalize on any of these opportunities though.
    • As of Seasons 4/5, his new female partner Eddie (nickname for Edit, a Hungarian name) is shown to be falling for him. Jamie himself seems to reciprocate, though both are still in denial about it, at least partially because admitting it would be mean that Sergeant Renzulli would be forced to reassign them to different partners.
  • Chronic Hero Syndrome: Any life insurance company that sells to him doesn't know it's job.
  • Drives Like Crazy: Averted, in contrast to the rest of his family, which leads to Erin arranging for him to teach Nicky how to drive.
  • Dude, Where's My Respect?:
    • Jaimie is a good cop with a strong moral compass and strong respect for the rules, and yet he is often shut down by other superior officers mainly because he's the commissioner's son, and they assume he's an Entitled Bastard as a result. The phrase "I don't care what your last name is" is something he's told a lot. And because he's Frank's son he's subject to enforced Limited Advancement Opportunities to avoid any appearance of favoritism. By Season 6, he's becoming bitter about this and has taken a level in jerkass as result.
    • In Season 6, he's subject to an IA investigation due to an accusation of excessive force, and Rev. Potter uses it as an excuse to launch another attack on the Reagan Family. When he expresses frustration at being taken off duty Frank tells him he's being treated like any other cop according to protocol, Jaimie points he's not - he's being treated worse because of last name, something the Jerkass DA investigating the case makes perfectly clear. Frank and Henry telling him he need to just "grin and bare it" don't help his attitude.
  • The Dulcinea Effect: Jamie cannot resist a Damsel in Distress.
  • Fair Cop: A cop and a resident Chick Magnet.
  • Forbidden Fruit: He becomes this to Eddie after Sgt. Renzulli informs them that they would be split up if they developed romantic feelings for each other.
  • Friends with Benefits: By season 4 he ends up in this relationship with a law school classmate.
  • Has a Type: As Erin states in "Partners", Jamie has always had a thing for "bossy, strong, and opinionated" women.
  • Hero Does Public Service: As part of an NYPD initiative to boost their public involvement in the wake of the Bitterman Houses events at the close of season 3 during which Jamie's partner Vinny was killed, Jamie is shown coaching basketball in a poor neighborhood in "Growing Boys". He gets involved in the plot when two gangsters start pressuring one of his players to rejoin the gang and one of them is inadvertently hit by a car when Jamie goes after them.
  • Honor Before Reason: Is very idealistic.
  • Incorruptible Pure Pureness: Jamie has shades of this.
  • The Infiltration: After he saved the life of mob heir Noble Sanfino while in plainclothes at the beginning of season 2, he has occasionally gone undercover in the Sanfino organization.
  • Ivy League for Everyone: Jamie is a Harvard boy.
  • Knight in Shining Armor: Again, the idealistic child — he was inspired to join the NYPD not just because of Joe, but because of the examples of his dad and grandfather.
  • Limited Advancement Opportunities: Acknowledged In-Universe, because Frank is worried that any promotion Jamie receives will automatically be seen as nepotism, so for the moment he's still a beat cop, something he's not happy with especially since most of his Academy classmates have already made detective.
  • Love Cannot Overcome: Jamie's girlfriend left him because she couldn't stand loving a cop with Chronic Hero Syndrome.
  • The McCoy
  • New Meat: Much of the focus on him is his professional and personal growth as a cop.
  • Nice Guy: Is even called "the patient one" by the rest of his family.
  • Old Cop, Young Cop: He's the Young Cop with Renzulli, but as if to specifically highlight his Character Development, he's the Old Cop with his season 4 partner Eddie Janko, a rookie.
  • Only Known by Their Nickname: His full first name is apparently "Jamison".
  • Screw the Rules, I'm Doing What's Right: Jaime has no problem arguing with or outright disobeying superior officers if he feels it's the right thing to do. Unfortunately this why he has an undeserved reputation as Entitled Bastard.
  • Swallow the Key: Frank Reagan didn't raise no fools. When confronted by some mob brokers, Jamie hastily swallows the thumbdrive he used to hack into their finances.
  • These Hands Have Killed: After his first line-of-duty fatal shooting. He did everything right, but he's still in shock, which is only exacerbated by the revelation that the perp was committing Suicide by Cop.
  • Took a Level in Badass: When the Sanfinos put out a hit on his alias and on Noble, he saved Noble's life again and coolly talked him into testifying.
  • Took a Level in Jerkass: By season 6, though it's justified and downplayed. For the former, anyone would start to become angry over being thought of as an Entitled Bastard and having Limited Advancement Opportunities because it may look like favoritism since your father is the commissioner; for the latter, while he does have more jerkass moments, Jamie does apologize for what he said to the person he hurt.
  • "Well Done, Son!" Guy: Jamie is always trying to make his father and (by some extent) Danny proud of him.

    Erin Reagan 
Played by Bridget Moynahan

Frank's daughter and Danny's and Jamie's sister, she is an Assistant District Attorney for Manhattan. She was married to a defense attorney, but they divorced before the series began and she is now a single mom. Her daughter Nicky recently raised her ire by deciding she wants to be the first female Reagan to become a cop.
  • All Girls Want Bad Boys: Erin gets weak in the knees when she meets art aficionado "Frank Weller." And she gets even weaker when he turns out to be an art thief (albeit one who returns art stolen by the Nazis during World War II to its rightful owners) who is using a fake alias.
  • Amicable Exes: Downplayed with her ex-husband Jack Boyle. They're reasonable but rather curt with each other, and the first time we meet him, Jack wonders why Erin still has her married name "Reagan-Boyle" on her door. She says it's the same reason people who have lost weight keep a "before" picture. Ouch. However, they still trust each other enough that Erin calls Jack to represent Danny after he gets framed. She eventually has the 'Boyle' removed.
  • Brainy Brunette: Very much so.
  • Daddy's Girl: Frank and Erin make it a habit to meet for lunch every Wednesday, and often lean on each other for advice on whatever case is going on.
  • Dating Catwoman: Erin has a habit of this.
  • Fanservice with a Smile: In her teens, Erin worked as a roller-bunny at a cocktail bar (specifically Roxy's). Frank was apparently aware of it (his mustache twitches in amusement at the memory) but he let it slide.
  • Former Teen Rebel: Many references to her teen years indicates that Erin would get into a lot of trouble.
  • Fox News Liberal: Zig-Zagged. Early on, Danny calls her a "liberal" when she gets particularly testy about his methods in dealing with bad guys. Still, she's characterized well enough to avoid any Strawman Political tropes. She actually comes across more as a libertarian: holding many conservative viewpoints, and having a tough stance on crime while still being very concerned about civil liberties and sometimes skeptical towards law enforcement, a position that often brings her into conflict with Danny. (Indeed, many conservatives in Real Life often accuse libertarians of being "liberal" because of this stance, so this is probably intentionally reflected in Danny's arguments with Erin.)
  • Glamorous Single Mother: Averted. Erin expertly juggles work and her teenage daughter, but has little time left for a social life.
  • Guile Heroine: Her skill as a rather clever attorney has come in handy many times.
  • Hello, Attorney!: Yes, she is hot.
  • Hidden Depths:
    • "Risk and Reward" shows Erin to be great at playing pool.
    • She absolutely adores Halloween.
  • Outnumbered Sibling: The only Reagan daughter out of four kids.
  • Overprotective Mom: To Nicky.
  • Principles Zealot: Is strongly committed to her principles and the law, and doesn't like Danny's Cowboy Cop tendencies. She has been known to bend on occasion, though.
  • Sex with the Ex: The C-plot in "Knockout Game" opens with Jack Boyle, Erin's ex, turning up in her shower the morning after they apparently went out on a date and slept together afterwards. It doesn't go anywhere because she decides he hasn't really changed.
  • Taking the Kids: Erin got Nicky after divorcing her husband, a defense attorney.

    Nicole "Nicky" Reagan-Boyle 
Played by Sami Gayle

Erin's daughter. She recently decided she wants to be the first female Reagan to join the NYPD. Her mom was thrilled.
  • Adorably Precocious Child: She's in middle school, but dresses and behaves like a thirty-two year old. She isn't cowed by any of the Reagans, regardless of age, and seems to view herself as the matriarch of the family.
  • Be Careful What You Wish For: She wants to be a cop and was eager to go on a ride along and from it sees her first dead body. She has many night terrors after that.
  • Boyish Short Hair
  • Brainy Brunette
  • Daddy's Girl: Despite the below trope, she is thankfully not lacking a male role model in her grandfather.
  • Disappeared Dad: She knows exactly where her dad is, but he usually takes little-to-no interest in his daughter's life. Erin and the rest of the Reagans are not amused. Henry refuses to shake Nicky's father's hand when they run into him at a party, and Frank bluntly tells him "You walked away from two of the most wonderful women I've ever known."
  • From the Mouths of Babes: In the early seasons. Around Seasons 4 and 5 she quite noticeably becomes more mature and outspoken.
  • It Runs in the Family: Nicky browbeats Erin into letting her stay out until 11:00. Frank wryly observes that she "made a very convincing argument."
  • The Matchmaker: Nicky is interested in pairing her mom off with her boss, DA Rossalini. She also lobbied for Erin to date the art thief.
  • Mouthy Kid: She has her moments.
  • Ordinary High-School Student: She's very well-behaved and intelligent, but increasingly chafes at Erin's stern restrictions on her social life. Still manages to remain quite level-headed through it all.
  • The Paragon: One of the smartest and most well-behaved students at her school, to the point where other kids' parents apparently have asked them why they can't be "more like that Nicky Reagan-Boyle." Nicky uses that fact to point out that she deserves the benefit of the doubt when she asks for more personal freedom.
  • Turn Out Like His Father: She intends to be a cop too. Erin is ambiguous about that.
  • Wise Beyond Their Years

    Linda Reagan 
Played by Amy Carlson

Wife of Danny and mother of their two grade-school boys (Jack and Sean), Linda works as a charge nurse at St. Vincent's Hospital. As the sole Reagan adult not professionally involved in law enforcement, her views sometimes contrast with those of her in-laws, but her loyalty to Danny and commitment to her patients and children are unquestionable.
  • The Chick: She's probably the most traditionally feminine woman in the series, a nurse and mother of two with no combat training who Doesn't Like Guns.
  • Clingy Jealous Girl: At one point, Linda worried that Danny would have an affair with a bar waitress and doesn't hide her jealousy over Danny helping out his ex-girlfriend.
  • Doesn't Like Guns: At least, she doesn't like that Danny dealt with Jack's fear after a shooting incident by teaching him how to safely handle his father's sidearm. She also at one point bought a revolver for self-defense after being mugged, but decided "it's not me."
  • Expository Hairstyle Change: Her hair gets shorter after she becomes a nurse.
  • The Glorious War of Sisterly Rivalry: An early episode features Linda's sister, a fashion designer, who she has a somewhat tense relationship with. Her sister appears on some level to believe that the rest of their family admire Linda's choice to be a nurse and a Staten Island family woman more than her decision to be a fashion designer.
  • Go Through Me: Linda is tending to a patient who's about to testify against a violent street gang. A gunman enters and tells her to leave the room, but she won't abandon her patient and deliberately steps between them.
  • Hello, Nurse!: A literal example. Linda is attractive and restarts her nursing career.
  • I Ain't Got Time to Bleed: When a key witness is shot in his hospital bed in the season 5 finale, Linda takes two in the abdomen, but she's so hopped-up on adrenaline she does a full round of CPR and doesn't even realize she was hit until after the witness has already flatlined.
  • Single Woman Seeks Good Man: While Linda can get exasperated at Danny's workload and angry at his negative traits, she loves him because he's a "good man".
  • Team Mom: The one first to offer support and has a gentle nature.

    Jack and Sean Reagan 
From left to right: Jack and Sean.
Played by Tony and Andrew Terraciano respectively

The two sons of Danny and Linda.
  • The Baby Of The Bunch: Sean is the youngest member of the entire Reagan family.
  • Children Are Innocent: Whenever a particularly adult topic comes up, Linda will immediately tell her sons to go eat in the kitchen or go upstairs to play.
  • Innocently Insensitive: Some of the questions they ask can be this, with them not understanding how certain topics can be painful and/or sensitive to the older members of the Reagan family.
  • Satellite Character: They only serve as the children on Danny and Linda who often ask questions regarding the current episode's topic.
  • Trademark Favorite Food: As "Growing Boys" revealed, their favorite meal are taco pies.


    Sgt. Anthony Renzulli 
Played by Nicholas Turturro

Jamie's training officer and partner through season 2. Took public credit for a rescue performed by Jamie in order to keep the latter's face out of the press for the benefit of the Sanfino undercover operation.
  • Big Brother Mentor: To Jamie.
  • Book Dumb: Renzulli isn't really a book smart person.
  • Demoted to Extra: In Season 3, he moves out from a patrol car to running the patrolmen of the 12th Precinct. He doesn't show up as often as the first two seasons now, though this is arguably to accentuate the fact that his former protege Jamie is now coming into his own as a mature policeman with a newbie partner of his own to train.
  • Donut Mess with a Cop: Likely donuts. At least it sure is something.
  • Old Cop, Young Cop: To Jamie. He is the old one.
  • Plucky Comic Relief: In Season 1.
  • Secret Keeper: He was asked by Frank to publicly take credit for a rescue Jamie performed, in order to protect the undercover operation.
  • Street Smart: Renzulli doesn't seem to have much in higher education, but he's very savvy and is an experienced cop.
  • Real Men Cook: Cooks a special Valentine's Day dinner for his wife, using a recipe his mom taught him.

    Detective Jackie Curatola 
Played by Jennifer Esposito

Danny Reagan's first partner. Leaves the series a third of the way into season three because the actress got sick.

    Abigail Baker 
Played by Abigail Hawk

Frank Reagan's executive assistant.
  • Badass Bureaucrat
  • Beware the Nice Ones: Baker is generally a quiet, efficient and demure personal assistant, who deftly manages Frank's schedule. She is also an NYPD detective, and whenever Frank needs dirt dug up, she delivers.
  • Deadpan Snarker: A jerk from a neighboring police department on Long Island is being extremely rude during Det. Baker's presentation at a police symposium...and she calmly shuts him up with a quick one-liner.
  • Girl Friday: For Frank.
  • Office Lady: Much of her role — until Frank needs a quiet investigation, at which the viewers are reminded that Baker is not just an office lady, she's also a detective.

    Detective Maria Baez 
Played by Marisa Ramirez

Danny's replacement partner starting episode 17 of season 3 (his third overall, he has another one played by Megan Boone for a few episode in the same season).
  • Action Girl: She's a female cop, so this naturally comes with the territory. And indeed, Maria has had to call on these skills a lot in the line of duty.
  • Big Brother Worship: Maria painfully remembers how she used to look up to her older brother Javi when they were kids, and he used to protect her from bullies. Nowadays, he's a recovering drug addict with a criminal history, while she's a police detective: the roles have reversed.
  • Fair Cop: Invoked in the season six premiere "Worst Case Scenario", where Baez plays up her good looks to pull a Distracted by the Sexy on some terrorism suspects. It works like a charm, up to and including a Wolf Whistle.
  • Foolish Sibling, Responsible Sibling: The responsible sibling to her older brother Javi, who grew up to be the foolish one.
  • Spicy Latina
  • Suspiciously Similar Substitute: For Jackie, at first. Both of them are savvy Latina detectives from rough backgrounds. She eventually gains Character Development.

    Officer Vincent "Vinny" Cruz 
Played by Sebastian Sozzi

Jamie's partner for season three. He grew up in the Bitterman Houses, a troubled housing project.
  • The Casanova: Definitely has an eye for the ladies.
  • Dark and Troubled Past: He grew up in a housing project beset with gangs and drugs, but managed to escape that life and join the NYPD.
  • Sacrificial Lion: In "The Bitter End" the gang that de facto runs the Bitterman Houses basically declares war on the NYPD. Vinny and Jamie are lured into the project and ambushed, and Vinny is fatally shot.
  • Sensitive Guy and Manly Man: The manly man to Jamie's sensitive guy.

    Officer Edit "Eddie" Janko 
Played by Vanessa Ray

Jamie's partner starting season four. A rookie cop.

    Deputy Commissioner of Public Information Garrett Moore 
Played by Gregory Jbara

Frank's de-factor chief of staff.
  • Brutal Honesty: Frank often doesn't like to hear it, but Garrett will give him his honest opinion no matter what. This is exactly why Frank trusts him.
  • Defeat Means Friendship: He once worked for Frank's political opponent, who was also trying to be commissioner.
  • Honest Advisor
  • Slave to PR: To be fair, this is his job. He's the Deputy Commissioner of Public Information, and he often has to give Frank advice that is sometimes frustrating, but in the end this is exactly why Frank trusts him so much: He's loyal, but he's not a yes-man, and will often remind Frank of how certain statements or actions will look to the general public outside the bubble of Frank's office.
  • Vitriolic Best Buds: With Frank. The two spend most of their time disagreeing, but there is a great amount of respect between the two of them, and Frank respects Garrett's advice.
  • What the Hell, Hero?: Has occasionally been on the receiving end when Frank thought he was out of line. Garrett himself delivered a rather eloquent one to Henry when one of Henry's statements lands Frank in hot water.

    Sgt./Lt. Sidney Gormley 
Played by Robert Clohessy

Danny's supervisor at the 5-4 squad for the first four and a half seasons. Later tapped by Frank to work for him at One PP to represent the interests of the department's rank-and-file.
  • Book Dumb: Grumbles that he liked it better before it was common for the department's rank-and-file to have degrees in criminology and tactics. Frank politely, but firmly, calls him out for this attitude.
  • Da Chief: He acts in this role towards Danny, far more than his father does.
  • Rank Up: Initially a sergeant, he's nearing retirement when Frank names him Special Assistant to the Commissioner (a title they made up because as a sergeant he's too low-ranked to be Chief of Department) in "Excessive Force". He gets promoted to lieutenant six episodes later in "Sins of the Father".
  • Reassigned to Antarctica: What he originally thought was going to happened to him after he shot off his mouth at a meeting. He even told Danny that he believed he was being sent to Siberia. Though it turns out Frank was giving him a Rank Up.
  • Turn in Your Badge: He orders Danny to do this in the Season 4 finale.
  • What the Hell, Hero?: He gets pissed off at Frank in one episode for not standing up for a lieutenant who accidentally killed a suspect.

Recurring Characters

    Mayor Carter Poole 
Played by David Ramsay

Mayor of New York starting in season 2.
  • Because You Were Nice to Me: One of the reasons he has a soft spot for Frank is that when he was a kid and Frank was just a patrol officer, Frank coached basketball for him.
  • Commuting on a Bus: Shows up less often from Season 4 onwards due to his being a series regular on Arrow as John Diggle. He still plays a crucial role in the plot though, and his scenes with Frank are typically some of the most crucial in the episodes where he appears.
  • Expy: Of President Barack Obama and possibly also of the famous Mayor Cory Booker of Newark, New Jersey. The Obama comparisons are noted early on when Henry notes that Carter was previously a "community organizer", a phrase frequently thrown around during the 2008 election to describe Barack Obama's earlier work. The Booker comparisons come from his status as a young, personable, media-savvy African-American mayor of a major city in the northeastern United States (indeed, as a neighbor in the Tri-State Area, Newark is just a few miles away from NYC).
  • Our Presidents Are Different: More like Our Mayors Are Different. He's a Mayor Personable/Mayor Minority combo.
  • Reasonable Authority Figure: Seems to work pretty well with Frank, too, though politics puts them at cross-purposes once in a while.
  • Sleazy Politician: Downplayed. He is not very sleazy but he does think like a politician and sometimes cuts corners in morality especially in the eyes of the more straitlaced Frank. Also he sometimes thinks to much about Nepotism toward his original constituents rather then thinking in terms of the whole city. In a way he is a more modernized and respectable version of a traditional New York ward boss. Indeed, at the beginning of the Season 3 finale "This Way Out", as the angry crowd at the town hall meeting says some harsh things about NYPD policy (much to Frank's chagrin), Mayor Poole is seen coolly analyzing the situation and very obviously thinking about how to placate his constituents. He then starts giving a rather politiciany speech, beginning "Now, I as a child of the projects myself, completely understand your frustration..." causing the audience members to groan. Still, although Frank doesn't like to hear it, Mayor Poole does need political popularity and influence in order to help Frank in certain situations.
    • Also, while he does clash often with Frank, at the core both of them are Not So Different: they both want what's best for the city of New York, it's just that they disagree on how to get there. As an example, both of them are concerned over terrorist threats, but Frank would rather work quietly and keep things off the news, while Poole would warn the whole world, partly because he doesn't want to be seen as someone who did nothing, but also because he is genuinely concerned for his city.
    • The most sleazy thing he's done is in Season 6, where due to Frank's bad publicity he's dragging his feet on wether to keep him on as the PC.

    Manhattan DA Amanda Harris 
Played by Amy Morton

Erin's boss, the District Attorney of the Borough of Manhattan.
  • Bitch in Sheep's Clothing: You don't want to be on her bad side.
  • Corrupt Bureaucrat: It turns out that she's got a long-standing deal with a high profile madam who has her people seduce high profile New Yorkers and get them on tape so that Amanda can blackmail them whenever she needs a favor. When Erin finds out and confronts her, Amanda calls Erin stupid for not being on board with this, and threatens her. It doesn't work.
  • Hoist By Their Own Petard: Threatens Erin's career when Erin confronts her on her corruption, but gets arrested in the end, ironically by the very same pair of FBI agents she'd been tricking into doing her bidding earlier in the episode. The look of shock on her face is priceless.
  • The Iron Lady
  • The Mentor: To Erin. She nurtures Erin's talent and notes "Y'know, it wasn't easy getting to where I am, but you know how I did it? In every job along the way, I made myself indispensible. The boss knew I had their back. And now I'm looking for people who can do the same for me. People who want a future in this office. People like you, Erin."
    • Brutally subverted at the end of her arc, in the most gut-wrenching way possible. Erin is horrified to discover that Amanda has been conspiring for years to entrap and blackmail high-level cops, politicians, pro athletes, and various celebrities in order to guarantee their assistance whenever she needs it (whether this assistance is solely for cases or possibly for darker, personal reasons is left open to speculation). When Erin confronts her on it, Amanda—her mentor—replies "Oh you stupid, stupid girl," in the most chillingly calm voice ever, breaking Erin's heart. She then goes to give her a horrifying Breaking Speech, including parts where she mocks Erin, saying "You waltzed in here like a glamorous model posing for a statue of Justice," and goes on to claim that she tried to show Erin how to really get things done, and then threatens Erin's career.
  • She Who Fights Monsters: Maybe. It's possible that she might have started out with good intentions, and that she really did do what she did to guarantee that she could put bad guys away; the problem is that in the process, she became a bad guy herself.

    Noble Sanfino 
Played by Eric Morris

While in plainclothes at a bar during the Season 2 premiere, Jamie Reagan saved a young man's life from an accidental overdose. The guy turned out to be Noble Sanfino, the heir to a major crime syndicate. NYPD's Organized Crime division parlayed Jamie's brownie points into an undercover assignment for the rookie cop.

    Kelly Peterson 
Played by Bebe Neuwirth

The new Inspector General as of Season 4.
  • Badass: A tough-talking Jersey Girl who made a name for herself fighting crime, through the legal system, in Newark, eventually rising to become the Essex County Prosecutor. She also shows herself to be a pretty skilled markswoman, as seen when she's practicing at the shooting range.
  • Belligerent Sexual Tension: Often at odd with Frank, but it's obvious they still have feelings.
  • I Love You Because I Can't Control You: It's heavily implied that she and Frank end up feeling this way about each other by the end of her arc. Each of them recognizes the necessary tension that their jobs require them to have in order to make sure that both sides are given a fair hearing, and although they often butt heads and argue, they come to genuinely admire and respect each other for being honestly passionate about their ideals. Humorously noted in one episode when Kelly threatens to subpoena Frank and even get him arrested if he doesn't cooperate with one of her investigations into something Frank deems classified information; Frank asks "Would you really throw me in jail?", to which Kelly responds "Yes....but with a heavy heart." Indeed, the reason she eventually quits her job is because she doesn't think she can keep up the adversarial nature her job requires that she have towards Frank...and it's heavily implied that it's because she's fallen for him.
  • Joisey: A native New Jerseyan, Kelly made her way up the ranks of the Newark DA's office, and was the lead prosecutor in Essex County, NJ before she accepted the position of Inspector General of the NYPD.
  • Obstructive Bureaucrat: Sometimes can come across as a hard case, but her heart's in the right place.
  • Old Flame: With Frank.
  • Put on a Bus: She quits at the end of the season because (paraphrasing her words) her job requires her to have an adversarial relationship with the PC, and she realizes she likes Frank too much. In her words, her job requires her to be antagonistic towards the Commissioner, or at least neutral. She says she's "supposed to be Switzerland"...but instead "I'm Bay Ridge" (Frank's neighborhood). She admits "I root for you, Frank."
  • Sympathetic Inspector Antagonist: When she's Frank's antagonist.

    Rev. Darnell Potter 
Played by Ato Essandoh

A spotlight-loving black pastor who frequently clashes with the NYPD and Frank in particular over race issues, including leveling accusations of Police Brutality.
  • Arch-Enemy: To Frank, or the closest thing he has to one.
  • Enemy Mine: Downplayed with Frank in one episode where both of them are angry that a white supremacist radio host is doing a show in New York (although he and Frank still disagree on how best to deal with the situation).
  • Karma Houdini: The man is blatantly corrupt and is involved with shady characters. It's rather impressive he hasn't been arrested himself for some of his antics, though it's implied that the NYPD is wary of giving him ammunition.
    • In his first appearance in "Black and Blue" he creates a confrontation with the NYPD by having a friend make a 911 call at his church and then having some of his parishioners screw with the responding officers, who happen to be Jamie Reagan and Tony Renzulli. Jamie and Renzulli get knocked down the stairs by a Scary Black Man and Renzulli ends up in the hospital.
    • In "Excessive Force" he basically pays off an immigrant family to keep quiet about the fact that a suspect is lying about Danny throwing him out a third-story window during his arrest.
  • Malcolm Xerox: Rev. Darnell Potter is a fairly transparent strawman of the Rev. Al Sharpton. Not only is he a demagogue, an accessory to murder, a crook, a hatemonger and a liar, he's waging a motiveless war on the NYPD to boot.
  • Sinister Minister: He claims to be a man of God, but he's really just interested in the position for the political power it gives him over the Black community.
  • Straw Man Has A Point: Notably averted, In-Universe. He has never once managed to make a truthful accusation of Police Brutality on-screen, but that hasn't stopped him from jumping on anything he thinks he could twist into one (or one he could create).
  • We Used to Be Friends: With Mayor Poole, until Poole broke it off when Potter's shady dealings came to light.

    Javier "Javi" Baez 
Played by Kirk Acevedo

  • Big Brother Instinct: Maria sobs that the brother who's now involved in crime used to be the guy defending her from "all those bullies when we were kids." Although she has trouble trusting him, Javi is actually still trying to protect her.
    • There is something of a reversal though: in the present day, although Javi is the older sibling, he now desperately wants to regain Maria's approval, due to his fall from grace.
  • Black Sheep: Javi broke the hearts of his parents and Maria by choosing to go down the path that he did. Maria still bitterly resents him for this.
  • Descent into Addiction: A key part of his backstory. This, along with his slide into criminal behavior, is what drove his family away. Now he's desperately trying to prove to them, particularly Maria, that he's clean again and no longer a criminal.
  • Foolish Sibling, Responsible Sibling: The foolish one, to Maria's responsible one.
  • The Informant: For the DEA and then the NYPD. When Maria and Danny force him to reveal this, laments that this is the "first time in [his] life" that he's done something that he thinks Maria will be proud of.
  • Knight Templar Big Brother: Unusually, it's not in a way that's harmful to others, but to himself: he's so desperate to show his little sister that he still loves her and to let her know that he's redeemed himself that he repeatedly goes to insanely dangerous, self-sacrificing lengths to prove that he's not a criminal anymore.
  • Recovered Addict
  • Redemption Equals Death
