He is portrayed by former Magnum P.I. star Tom Selleck. Biography and family ( Edit ) Frank is the younger son of Henry ( Len Cariou ) and Betty Reagan, born in Bay Ridge, Brooklyn, New York in the early 1950s. His older brother, Peter Christopher Reagan, died of leukemia at the age of 18 months over a year before Frank was born. Frank married Mary Margaret Reagan in the early 1970s, and they have four children together : Danny, Erin, Joe, and Jamie. Each of Frank 's sons followed him into the NYPD : Danny ( Donnie Wahlberg ) is a Detective 1st Grade and lead investigator with the 54th Precinct 's Detective Squad ; Joe was a Detective with the Warrants Squad who was murdered on the orders of his partner Sonny Malevsky ( Michael T. Weiss ), the leader of a corrupt gang of police officers called the Blue Templar ; and Jamie ( Will Estes ) is a patrol officer assigned to the 12th Precinct with a law degree from Harvard University. Frank 's only daughter, Erin ( Bridget Moynahan ), is also in law enforcement as a Manhattan Assistant District Attorney. Erin was promoted to Deputy Bureau Chief of the NYCDA 's Trial Bureau in 2013. In addition to his children, Frank is also a loving grandfather to Erin 's daughter, Nicky Reagan - Boyle ( Sami Gayle ), and Danny 's two children, Jack ( Tony Terraciano ) and Sean Reagan ( Andrew Terraciano ). In one episode, it is mentioned that Frank 's wife 's grandfather was one of the builders on the Brooklyn Bridge in the 1870s and ' 80s. Frank 's dad 's father, Charles Reagan, was an Irish immigrant who served in World War I before becoming a police officer. Charles was the one who taught him how to fish. In `` Whistle Blower '' ( season 2, episode 10 ), Frank mentions his great - uncle Teddy Reagan, a member of the NYPD Mounted Unit, who spent a cold night in a boxcar with his horse, Dolly, and woke up in Pittsburgh. Growing up, Frank became friends with Angelo Gallo ( Chazz Palminteri ), who grew up to be one of the top mafia lawyers. After Gallo was shot on the orders of a former client, Frank has him publicly arrested for hindering prosecution, to protect him from being considered a rat. Another close friend of his is Monsignor Walter Donahue, a member of the city archdiocese. However, it is also mentioned that Frank does not have many friends in the New York City Council, especially after Danny 's arrest of city Councilman Tony Mancini ( Richard Burgi ), a former NYPD detective, for domestic abuse. Service ( Edit ) After serving in the United States Marine Corps during the Vietnam War ( during which time he held the rank of Lieutenant and was awarded the Navy & Marine Corps Achievement Medal ), Frank became the third generation of Reagans to become a police officer. He began his career as a patrol officer stationed at the 27th Precinct. After three years on patrol, he was promoted to Detective 3rd Grade. Since then, he has served in various positions across the city, including Chief of the Brooklyn South Division and the Chief of Department of the NYPD, culminating in being appointed Police Commissioner. In the 1970s, Frank led the attempt to apprehend Whitey Brennan, the head of the Westies, at his grandson 's baptism. Due to the chaos, a shootout ensued in which two police officers were wounded and four people from the Westies were killed, including Whitey 's wife and grandson. In the early 1980s, Frank served in the Canine Unit as a dog handler. However, he transferred out of the unit after Greta, his partner, was shot and killed by a burglar Frank sent her in after. From 1995 to 1999, Frank was the Commanding Officer of the Special Investigations Unit, a special anti-narcotics task force. On September 11, 2001, Frank was working in the North Tower when the South Tower collapsed. He spent days at Ground Zero, and took refuge at St. Paul 's Chapel, where he and other officers slept in the pews. As a `` Member Of the Service '' ( MOS ) prior to 1994, Frank continues to carry a revolver ( a Colt Official Police `` Fitz Special '' that originally belonged to his father and grandfather ) as his duty weapon. He also owns a Colt Government M1911. At one point, he uses it on a serial rapist who was about to rape and kill Erin. As police Commissioner ( Edit ) List of Blue Bloods characters New York City Police Commissioner Incumbent Assumed office September 24, 2010 Appointed by Frank Russo Carter Poole Preceded by Commissioner Connors Frank was appointed the Police Commissioner by Mayor Frank Russo ( Bruce Altman ). In 2011, after the election of Carter Poole ( David Ramsey ), Frank offers to tender his resignation, but Poole decided to keep Frank on as PC. In 2015, after Mayor Poole 's successful reelection, Frank struggles with whether he even wants to stay on for another four years as PC, assuming the Mayor even asks him to. He ultimately decides to stay for `` as long as the Mayor 's head is in his ass '' ( which was remarked as indefinitely ). The Mayor officially asked Frank to re-up in February 2016 and he agrees. Frank has an indifferent attitude towards politics, often taking on the mayor and numerous reporters who misinterpret his actions. He tries hard not to judge people, and tends to purse his lips together when hearing bad news or the horrific details of an ongoing case. He also refuses to play favorites ; in season 4, he mentions that he is afraid to recommend Jamie, now with four years on the force, for promotion to Detective because it would look like nepotism. In 2011, Frank was shot by Kevin Brennan ( Jack Gwaltney ), the son of the former head of the Westies who Frank arrested back in the ' 70s. In 2013, Frank is the target of an assassination attempt by Hector Santiago ( Omar Maskati ), a mentally - challenged teenager of the Bitterman housing projects who is tricked by a member of the Los Lordes gang who declared war on the NYPD. The bullets miss Frank, but hit Mayor Poole, leaving him paralyzed and confined to a wheelchair. One of Frank 's predecessors, `` Crooked '' Commissioner Connors, served time in a federal prison after his term as PC was completed and left him with more than one mess to clean up, including Officer Thomas Sculley ( Warren Kole ), one of four patrol officers who, a few months after 9 / 11, accidentally shot an unarmed Muslim teenager, and was acquitted of all charges and allowed by then - Commissioner Connors to keep his job. In 2016, Officer Sculley, who had kept his head down for the last 14 years and made great strides to atone for his horrible rookie mistake, passed the Sergeant 's exam with flying colors. Frank was reluctant to promote him, lest tensions between the citizens and the police grow even worse and ultimately offered Officer Sculley a choice : transfer to another city ( Long Island, Albuquerque, New Mexico, Boulder, Colorado, or San Diego were among the departments Frank talked to ) or take his promotion to Sergeant and ride a desk at the NYPD Erie Basin Auto Pound in Brooklyn for the rest of his career. In the first season, Frank is well regarded and respected by his officers and his city, to the point where the Mayor felt threatened by his popularity ; however, by season 6, public opinion regarding the police -- and him personally -- has changed so drastically that he gets booed off - stage while speaking at Columbia University. However, in season 7, new mayor Margaret Dutton affirms that his polls are better than any of the NY Mayors Frank was nearly served with a vote of no confidence by the NYPD rank and file in 2012 when he publicly apologized for the accidental shooting of a black man by a rookie patrol officer ( Corbin Bleu ) instead of waiting for the official report.

While up for a promotion to Deputy Chief as the Deputy Commander of Patrol Borough Manhattan South, it was revealed that he had been cooking the books for his precinct 's CompStats.

He is portrayed by Donnie Wahlberg. Biography ( Edit ) The oldest son of the current New York City Police Commissioner Frank Reagan and his wife Mary, Danny grew up in Bay Ridge, Brooklyn with a younger sister, Erin, and two younger brothers, Joe and Jamie. He was happily married to Linda since 1996, with whom he has two sons, Jack ( b. 2000 ) and Sean ( b. 2004 ), until Linda 's death between seasons 7 and 8. They lived on Staten Island until their home was destroyed in a fire in the season 7 finale, which was set by a drug cartel in retaliation to a recent bust Danny made. During high school, Danny dated Marianne Romano ( Charisma Carpenter ), who was described by his partner Baez as `` the queen bee, super good looking, a little crazy, and dynamite in the sack '' to which he agreed. As a young man, Danny worked construction. For a class project of Nicky 's, Danny mentioned that when he was three years old, he wanted to be a firefighter for Halloween, but his grandfather Henry swore that as long as he was alive, no Reagan would ever be a member of the FDNY, got him into a police uniform, and he `` never took it off '' until he made Detective. On the job for 15 years ( as of season 1 ), Danny took a leave of absence from the New York City Police Department to serve two tours in the Iraq War as a Marine. Danny saw combat in Fallujah, and was the only member of his platoon to come home alive ( resulting in some post-traumatic stress ). During his time in the Marines, Danny was decorated for heroism. He is old - school ; his hotheadedness and harsh methods of detective work sometimes get him in trouble, which his father worries about. When asked if his son `` crosses the line '' and violates procedure from time to time, Frank answered, `` I think he walks on the line ''. Danny is hard on other policemen and detectives when he feels they are unprofessional or not doing their duty to its utmost. He is currently assigned to the Detective Squad of the 54th Precinct, and partnered with Detective Maria Baez. In `` Most Wanted '', it is mentioned that he leads the Manhattan South Detective Borough in both collars and complaints. In `` Love Stories '', he and Baez are awarded the NYPD Medal for Valor for their actions in `` Partners ''. As a detective with the NYPD, Danny carries a Kahr K9 in 9 × 19mm as his duty weapon, and drives a Dodge Charger on duty, which replaced his previous Chevrolet Impala 9C1. He also owns a Glock 19 in 9 × 19mm, and previously used a Smith & Wesson 5946 in 9 × 19mm. Danny drove a Jeep XJ Cherokee as his personal / family vehicle from Season 1 to Season 5, whilst Linda drove a rather troublesome 2001 Kia Sedona / Carnival ; this vehicle was replaced when Henry lost his driver 's license and gave Linda his car. In Season 6, Danny 's Cherokee was replaced by a fourth - generation Ford Explorer. Partners ( Edit ) Over his career, Danny has had numerous partners. Detective Darryl Reid ( Malik Yoba ) -- Partnered together for `` eight months seven years ago '' ( c. 2008 ), Reid 's career came to an end ( and put Danny 's in jeopardy ) when it was revealed that he planted evidence to secure a murder conviction. Detective DeMarcus King ( Flex Alexander ) Detective Ava Hotchkiss ( Yvonna Kopacz Wright ) -- First partner of Danny 's when he was assigned to Major Crimes. Detective First Grade Jackie Curatola ( Jennifer Esposito ) -- From 2010 until 2012, Danny was primarily partnered with Detective Jackie Curatola at the 54th Precinct. In 2012, Jackie took early retirement from the NYPD after starting to show signs of burning out. Detective Kate Lansing ( Megan Ketch ) -- Assigned to replace Detective Curatola in 2012, Detective Kate Lansing worked with Danny for almost three months. She transferred back to Internal Affairs after the arrest of Captain Derek Elwood ( Nestor Serrano ), who framed Danny for possession of narcotics in order to prevent him from discovering his gambling problem. Detective Candice `` Mac '' McElroy ( Megan Boone ) -- A temporary addition to the 54th Precinct, Detective Candice McElroy briefly served as Danny 's partner in 2013.

Biography ( Edit ) A New York County Assistant District Attorney and single mother, Erin is the second child and only daughter of the current New York City Police Commissioner Frank Reagan and his wife Mary. She grew up in Bay Ridge, Brooklyn, with three brothers, Danny, Joe, and Jamie. It is implied throughout the series that she had something of a wild streak growing up ( unlike her daughter ). In season 5, it is mentioned that she graduated top of her class from Columbia University ; she later went on to attend Fordham University School of Law. In season 6, Erin celebrated her 40th birthday. Erin is divorced from John `` Jack '' Boyle ( Peter Hermann ), a criminal defense attorney, whom she met when they were 19. In `` Old Wounds '', she finally changes her name from Erin Reagan - Boyle back to Erin Reagan. Since her divorce, Erin has had a few romantic interests. She and her boss, District Attorney Charles Rosselini ( Bobby Cannavale ), flirted with each other and even shared a kiss after a date, but nothing ever came of it mainly due to Erin 's reluctance with the idea of dating her boss. In 2011, she met Jacob Krystal ( Fred Weller ) at an art gallery ; she later learned that he was an art thief who returned once - stolen works to their rightful owners, and he left town. In 2013, after being shot in a courtroom hostage situation, she started up a fling with her ex-husband Jack but broke up when they started getting serious again ( lest he break her heart again, or their daughter find out that they were once again `` hooking up '' ). In 2014, she met Robert McCoy, a defense attorney, on a speed - date, and the two became romantically involved until he was appointed interim District Attorney, at which point she said she ca n't sleep with her boss. Erin is almost raped and killed in `` Re-Do '', though Frank saves her life by shooting her attacker dead. In `` To Protect and Serve '', Erin is taken hostage and shot in the arm at the courthouse. She is saved by Danny after he says a coded message, `` Please, do n't hurt my family, '' after which she dropped to the ground, and Danny shot her assailant. It is revealed that their father taught them this when they were young, as a plan in case one of them was ever held at gunpoint. In `` Working Girls '', Erin is offered the position of Deputy Mayor of Operations by Mayor Poole, but she turns him down. In `` Ends and Means '', Erin is promoted from Senior Counsel to Deputy Bureau Chief of the Trial Bureau. In the season four finale, she filed a complaint against her boss, Bureau Chief Amanda Harris, upon learning she had abused her power. In season six, Erin was considered for a judgeship. Like the rest of her family, Erin is licensed to carry a firearm. Her weapon of choice is the Glock 19 in 9 × 19mm and, according to Frank, she 's a better shot than Danny and Jamie. In season 8, we found out Erin wanted to join the police force like her family, wanted to take the exam but it was n't for her and chose law and become a prosecutor.

Anthony Renzulli ( his training officer ) in seasons one and two, Officer Vinny Cruz in season three, and Officer Eddie Janko since season four. During his first year on the job, Jamie was the one who continued Joe Reagan 's investigation into the Blue Templar. In season two, he takes advantage of a chance opportunity to go undercover in the Sanfino crime family. In `` Front Page News '', Jamie gets his first kill in what he learns is a suicide by cop ; the shooting leaves him with brief post-shooting trauma ( more so since Bryant 's death was found to be a suicide - by - cop ), but between his family and the NYPD psychologist ( Annabella Sciorra ), he quickly recovers. In season four, he begins to express concerns because both his father and brother had made detective by that point in their careers, while he is still a patrol officer. In season six, Jamie is studying for and is considering taking the Sergeant 's exam ; however, he ultimately decides against taking it. In season seven, Frank gets wind from the ranks that he may be the only thing holding Jamie back from becoming a detective. When pressed, Jamie informs his father that he 's happy where he is in his career and does n't necessarily want another assignment. In that same episode, it is mentioned that Jamie is the only NYPD employee with a Harvard Law degree that walks a beat. While attending Harvard, Jamie met and became involved with Sydney Davenport and the two even got engaged. However, Sydney broke up with him a few months after he became a police officer when realizing the true danger of his career. Since 2013, there has been significant romantic tension between Jamie and his patrol partner, Eddie Janko, with the two even sharing a kiss. Despite this, Jamie has chosen not to act on his feelings after learning that Sergeant Renzulli would reassign them to new road partners if they did. Despite agreeing to keep things professional, there remained lingering romantic tension between the two. In 2018, Jamie and Eddie get engaged along with choosing to remain as partners on the job after discovering there is no official rule against it. As a uniformed patrol officer, Jamie drives a patrol car on duty and carries a Glock 19 in 9 × 19mm as his duty weapon ; while in plainclothes, Jamie uses the smaller Glock 26 in 9 × 19mm. While off - duty, Jamie drove his brother Joe 's 1971 Chevy Chevelle Malibu SS until it was sabotaged and totaled by the Blue Templar. Partners ( Edit ) Over his career, Jamie has had a few partners. Sergeant Anthony Renzulli ( Nicholas Turturro ) -- Jamie 's training officer, Sgt. Renzulli knows the beat of his precinct very well and often offers Jamie good advice when he needs it. He believes Jamie will make a great cop, and often pokes fun at him for abandoning a lucrative law career. Officer Vincent Cruz ( Sebastian Sozzi ) -- Jamie 's partner who grew up in the Bitterman housing projects neighborhood of New York City. In `` The Bitter End '', Cruz and Jamie are patrolling near the Bitterman Houses and come across a purse snatcher who leads them on a chase through the project. The purse snatching proves to be a setup, and both officers find themselves under fire from Los Lourdes gang members. Cruz is hit twice in the neck and despite Jamie 's best efforts, he dies at the scene from massive internal bleeding. Officer Edit `` Eddie '' Janko ( Vanessa Ray ) -- A younger police officer and Jamie 's current partner. Feisty and strongly opinionated, she is very passionate when it comes to her job. As of late, her latent romantic feelings for Jamie have become more apparent, but they mutually decided not to pursue a romantic relationship lest they lose their partnership. However, they announced their engagement to the Reagan family in the season 8 finale, `` My Aim Is True ''. Henry Reagan ( Edit ) Former Commissioner Henry Reagan is Frank Reagan 's father.

Biography ( Edit ) The retired Police Commissioner and father of Frank ( grandfather of Danny, Erin, Jamie, and the late Joe ; great - grandfather of Nicky, Sean, and Jack ).

Henry was a Marine in World War II and Korea, and joined the NYPD in 1952. He got married in 1955. Like his grandson Danny, Henry is socially conservative and hates the political correctness of modern law and order. His wife of 46 years, Betty, died December 2, 2001.

Frank reluctantly tells Abigail later that he found out Bullman mainly wanted to hire her to have someone in his ranks who could pull favors at 1PP.

When Danny was framed for narcotics possession, Henry hired Jack as his attorney. Jack and Erin briefly got back together after surviving a courtroom hostage crisis, but Erin ended it when they started getting serious again ( lest he break her heart again, or their daughter find out that they were once again `` hooking up '' ).

( Whether this assistance is solely for cases or possibly for darker, personal reasons is left open to speculation. ) She is portrayed by Amy Morton. Robert McCoy ( Edit ) A defense attorney Erin met on a speed - date. He was an Assistant District Attorney in Brooklyn for twelve years before leaving to join private practice in 2008. After Bureau Chief Amanda Harris was fired, McCoy was appointed the interim New York County District Attorney. This caused Erin to break off their relationship, saying she ca n't sleep with her boss.

As a result, he is serving a prison sentence. He gets a lighter sentence after busting a prison guard drug ring.

In `` Back in the Day '', Eddie reveals her aspirations of making detective, having signed herself and Jamie up for a surveillance assignment for one of the precinct 's detectives. While awaiting their target, Eddie chose to remain at her post when Jamie chose to respond to an officer - down call, which proved to be false. This led to a brief conflict between them, with Jamie threatening to get a new partner if she ever goes against an emergency call again. There has been significant romantic tension between Eddie and Jamie since the middle of season four, the two even sharing a kiss. Despite their attraction, Jamie had chosen not to act on his feelings after learning that Renzulli would reassign them to new partners per NYPD protocol. Nevertheless, there continued to be romantic tension lingering between the two, which had become much more apparent when they both acknowledged to each other how they feel, leading to another kiss. Despite this, they agreed not to further act on their feelings since they do n't wish to jeopardize their partnership. In the season 8 finale, after a life - threatening situation, Jamie and Eddie accepted their feelings and got engaged. When they announced their engagement to the Reagan family, Frank offered Eddie her choice of a new precinct assignment. However, Jamie pointed out that there is no actual regulation prohibiting married NYPD officers from being partnered on the job. Therefore, they have decided to remain partners as well. As a uniformed patrol officer, Eddie drives a patrol car on duty and carries a Glock 19 in 9 × 19mm as her duty weapon.

In season 7 Potter suffers a personal tragedy when his teenage son is murdered by one of the youths he once sheltered ; Frank consoles him, revealing that his son Joe was killed by a corrupt cop. This, along with Danny 's successful capture of the killer, softens some of Potter 's bitterness towards the Reagans. References ( Edit ) Jump up ^ `` Men in Black ''. Blue Bloods. Season 3.
