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 Get Their Man
  • 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 Cops Love Jesus
  • 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.

  • Action Dad
  • Always Gets His Man: Oh yes.
  • Badass Grandpa/Papa Wolf/Beware the Nice Ones: Do NOT hurt a member of his family. He'll put you down without a word.
  • 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
  • By-the-Book Cop
  • Cool Shades
  • Da Chief
  • A Father to His Men: Cares deeply about the NYPD and his sons.
  • Four-Star Badass
  • The Good Chancellor
  • 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.
  • Like Father, Like Son: Despite being able to adapt with the times, their scenes together show that Frank is very close to Henry.
  • 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.
  • The Patriarch
  • Reasonable Authority Figure: Out of all the family members, you can usually count on Frank as being 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.
  • Survivors 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.

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.
  • 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.
  • 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.
  • 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.
  • 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.
  • Retired Badass/Retired Chief: Henry is a former police commissioner.
  • 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.

  • Aloof Big Brother: Isn't very close to Jamie, due to their age differences.
  • Always Gets His Man
  • Badass
  • Characterization Marches On: 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 regular thing for him.
  • 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).
  • Deadpan Snarker: Always ready with the quips.
  • Fighting Irish
  • 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.
  • Good Is Not Nice: Very much so.
  • Guile Hero
  • Happily Married: To his wife, Linda.
  • Hot-Blooded
  • Jerk with a Heart of Gold: 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.
  • 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.
  • 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.
  • Mysterious Past
  • 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
  • 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.
  • 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.

Joe Reagan (deceased)

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

Jamie Reagan

Played by Will Estes

The youngest of Frank Reagan's surviving children, and a rookie cop. 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.

  • By-the-Book Cop: Very much so; this is part of the tension between him and Danny.
  • 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.
  • The Dulcinea Effect: Jamie cannot resist a Damsel in Distress.
  • Fair Cop
  • 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.
  • 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.
  • Heroic BSOD/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.
  • 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.
  • 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".
  • 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.
  • 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.

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.

  • 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.
  • 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.
  • 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.
  • Fox News Liberal: Played with. 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.
  • 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.

    The NYPD 

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/Kicked Upstairs: 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.
  • The Danza
  • 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).

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.

Officer 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 sometimes 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.
  • 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.

  • 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.
  • Hey, It's That Guy!: He's an NYPD sergeant here...and also in a memorable scene in The Avengers, where Captain America helps him battle the Chitauri, and gives him a strategy to evacuate civilians out of the affected area.
  • 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 

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.

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.
  • Hey, It's That Guy!: Played by David Ramsey, aka Diggle on Arrow. He began his role on Arrow during his second season on Blue Bloods. He has appeared somewhat less frequently since Arrow began, due to his being a character on both shows, but still remains a very important character on Blue Bloods.
  • 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.
    • 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.

Kelly Peterson

Played by Bebe Neuwirth

The new Inspector General as of Season 4.
