  Julianna Margulies as Alicia Florrick: The titular character of the show, and the wife of Peter, a disgraced State's Attorney; Alicia returns to work as a junior litigator at the law firm Stern, Lockhart & Gardner in part through her old law school friend Will Gardner, whom she has feelings for.
Having spent so many years as "the good wife", Alicia finds herself at the bottom of the career ladder, trying to juggle both home and professional life with the ongoing scandal surrounding her husband with whom she has two children, Zach and Grace.
Alicia is smart, independent, fiercely protective of her children, and much more than just a good wife.
She excels at keeping a cool exterior.
She is rarely ruffled and almost always thinks through what she is going to say, choosing her words for maximum impact or sting.
Alicia graduated top of her class from Georgetown University Law Center over 15 years ago in the mid-1990s.
After graduation she worked at Crozier, Abrams & Abbott for about two years, but left due to her kids and her husband's career.
Her maiden name is Cavanaugh and she has a younger brother, Owen, who is gay and the polar opposite of Alicia personality-wise, but they do love each other.
Her mother's name is Veronica Loy.
In season 3, Alicia is a third-year associate at the firm.
She and Peter are separated, and she has a sexual affair with Will but by mid-season she breaks it off.
Alicia struggles with her feelings for Peter.
She is deeply hurt and has not entirely forgiven him, but still loves him.
Toward the end of season three, Peter announces his candidacy for governor of Illinois; Alicia stands at his side as he makes the announcement.
In season 4, Alicia gets and takes a promotion as an equity partner of the firm and begins planning to start a new firm with Cary.
Archie Panjabi as Kalinda Sharma: The firm's in-house private investigator.
Kalinda previously worked for Peter for three years.
He fired her after accusing her of working two jobs.
Kalinda is unflappable, inscrutable, fiercely private, and occasionally physically violent.
She is exceptionally good at her job, although her tactics are not always strictly legal.
She is often the key to the firm winning whatever case they are working on, usually at the 11th hour.
She generally does not work well with others.
Although Kalinda doesn't let many people close to her, she becomes good friends with Alicia, with the aid of tequila shots, and she feels protective of Alicia.
After becoming good friends, Alicia finds out Kalinda had a one-night stand with Peter before she knew Alicia, damaging their friendship but over time, the two start to reconcile.
Kalinda has a cynical, misanthropic outlook on human behavior.
She is bisexual and has a series of relationships through the show, mostly with women and often because they can help her with a case.
She often plays a major part in winning cases for Lockhart & Gardner, although not always ethically or legally.
Very little is known about her when the series begins, and she is incredibly secretive about her past.
The character's signature wardrobe piece has become a pair of knee-high boots; the character initially wore pumps but Panjabi felt that boots "grounded her in the character."
In season 4, it is revealed that Kalinda has an abusive husband called Nick Saverese, played by Marc Warren.
Josh Charles as Will Gardner (Season 1-5): An old friend of Alicia from Georgetown University and a named senior partner at the law firm.
Will generally has a good working relationship with Diane Lockhart, his co-managing partner at the firm, and the two demonstrate a shrewd ability to guide their business, even through difficult times.
Will plays in a regular pick-up basketball game with other attorneys and judges, and has friendships with the players that are eventually scrutinized.
In season 3, Will and Alicia have an affair.
Will is suspended from practicing law for six months as punishment stemming from an old bribery scandal.
In season 4, he returns to the firm.
Will and Alicia knew each other when they attended law school at Georgetown University and he helped her get her job with the firm and is constantly trying to avoid appearing as if he favors her.
This is complicated by the fact that he has feelings for Alicia, and when she and Cary leave to start their own firm which competes with him, he takes this betrayal personally.
In episode 15 of the fifth season, he was killed in the courtroom by his client Jeffrey Grant (played by Hunter Parrish).
Christine Baranski as Diane Lockhart: A named senior partner at the firm, she supports other female lawyers.
She is liberal and is a champion of women's causes, thus having strong opinions on many issues, including an extreme dislike of guns and violence, although in one plot line she had a romantic relationship with a conservative ballistics expert.
She speaks fluent French and although she is not married, seems to have an active social life.
Among her paramours is Kurt McVeigh, a firearms expert and conservative Republican, whom Diane is drawn to despite their political opposites and her dislike of guns, and they eventually marry.
Although she is initially skeptical of Alicia Florrick's abilities as a lawyer when she joins the firm, Diane becomes a sort of mentor to her.
But she is a mentor at a distance, and her support often comes by way of cryptic advice that only points Alicia in the right direction.
She does not hesitate to tell anyone when she thinks they are wrong.
Diane is often torn between supporting Alicia and Cary Agos when the two are in competition.
Matt Czuchry as Cary Agos: A young Harvard-educated lawyer who, in the first season, begins as a first year associate at Lockhart Gardner with Alicia Florrick.
In the first episode, it is established that there is only one permanent position, putting Cary into competition with Alicia.
At the end of first season, the firm selects Alicia, and Cary goes to work for the state attorney's office.
In season 3, Cary is appointed Cook County Deputy State's Attorney, though he subsequently demotes himself for having an in-office affair.
Dissatisfied with the demotion, he accepts an offer to return to Lockhart Gardner.
He is often placed in rivalry with Alicia and sometimes resents her for this and her political connections thanks to her husband, Peter Florrick, the disgraced State's Attorney.
His own career trajectory takes many twists and turns, often because of bad luck, but Cary maintains his integrity and loyalty to individual relationships he has formed.
He seems to have a crush on Kalinda Sharma, the firm's investigator.
It is later revealed that Cary has a very difficult and distant relationship with his father, Jeffrey Agos, a lobbyist in Washington, D.C., who does not ever seem to think Cary is good enough.
As season 4 ends, after not getting the partnership at Lockhart Gardner that he sought, he forms a new firm bringing with him the other fourth year lawyers at the firm, and manages to convince newly minted Lockhart Gardner partner Alicia to come with them.
Graham Phillips as Zachary "Zach" Florrick: The teenage son of Alicia and Peter Florrick, the eldest of the Florrick’s children, the older brother of Grace Florrick, grandson of Jackie Florrick and Veronica Loy (Alicia’s mom), and nephew of Owen Cavanaugh.
Zach has an interest in politics, at one point joining Peter's campaign as an intern.
Zach is smart, stubborn and also has a strong sense of right and wrong, which has led to not be afraid of his questioning authority figures at times.
Zach's computer skills and technical know-how also expose lies that are being spread about his dad.
Beyond his computer skills, he shows an aptitude for using the law like his mother.
He is protective of his mom because of what his father has put her through.
Zach is coping with his parents' separation and starting at a new school and also starting to date.
Throughout the series, Zach dates the scheming Becca and later a girl named Neesa who happens to be African-American and whose race and religion are occasionally brought into his father's campaign, which causes some issues.
This becomes complicated when his father is released from prison and contemplates a run for office, making his children's life political fodder, despite their mother's best efforts.
Makenzie Vega as Grace Florrick: The teenage daughter of Alicia and Peter Florrick, the youngest of the Florrick’s children, the younger sister of Zach Florrick, granddaughter of Jackie Florrick and also Veronica Loy (Alicia's mom), and niece of Owen Cavanaugh.
Although pretty and compassionate, she is friendless, which is most likely due to her outwardness.
She begins to become deeply religious, thanks to a friend at school, much to Alicia's bemusement, and question her faith and read the Bible, which Alicia doesn't understand, but tries to support.
She is naïve and young for her age.
She has a tutor, Jennifer, who likes to bust out dancing in public.
She has many questions about her father's infidelity, which she does not understand.
She previously idolized her father and despite his sins, she wants her parents to get back together.
Grace was not happy about the move from their house in Highland Park to their apartment and initially struggles to make friends in school.
Alan Cumming as Eli Gold: Peter Florrick's campaign strategist and crisis manager, Eli consults for Peter when he considers a return to office.
His style of management is to be blunt, often rude.
Eli is politically astute and doesn't waste time with niceties.
Eli is separated from his wife, Vanessa Gold (played by Parker Posey), who has political aspirations of her own, and has a daughter, Marissa (played by Sarah Steele), who is similarly outspoken like her mother and shares a healthy relationship with her father.
Eli believes that securing the support of Peter's wife Alicia is crucial to any ambitions he may harbor, and he quickly realizes that Alicia is no pushover and his usual wife-coddling techniques will not work.
He mostly seems to respect the boundaries Alicia sets up, particularly where they concern her children Zach and Grace.
As a top political consultant who is also an expert in damage control, Eli has talks with Diane Lockhart and Will Gardner about joining their firm in some way.
Eli seems genuinely invested in Peter Florrick and respects both him and Alicia, although she is often a frustrating enigma to him.
He has a brief shot at romance with Natalie Flores (played by America Ferrera), a student who worked in the past as a nanny for Wendy Scott-Carr.
Eli leaks details to the press of Natalie's status as an illegal immigrant but as he comes to know her he is seen to regret this and later helps her get a job as an intern at Lockhart & Gardner.
Cumming's portrayal of Gold has been compared to Rahm Emanuel.
He was promoted to the main cast in season two.
Eli is Jewish, but not very religious.
He does, however, request the Sabbath off.
In season 5 Peter asks him to be his chief of staff, which he accepts.
Zach Grenier as David Lee: Head of Family Law, a divorce lawyer, and an equity partner at Lockhart/Gardner.
He is the head of the family law division, which is responsible for a sizeable chunk of the firm's income so he has more sway than Diane Lockhart or Will Gardner would like.
David is generally in a bad mood.
He scowls, pouts, whines, complains and connives when he doesn't think things are going his way.
More than anything, he is concerned with making money.
He particularly hates Julius Cane, the firm's head of litigation and an equity partner.
Nevertheless, at rare moments, Alicia Florrick turns to him for help and he comes through.
After recurring in the first four seasons, he was promoted to a series regular for the fifth season.
Matthew Goode as Finn Polmar: Introduced in the fifteenth episode of the fifth season; Finn is responsible for the prosecution case against Jeffrey Grant (played by Hunter Parrish).
During a shooting in the courtroom, Finn is wounded along with Will Gardner, although Finn survives his injuries.
Finn is meant to be a replacement for Gardner.  
Season synopses.
Season 1.
As a junior associate at a prestigious Chicago law firm, Alicia Florrick joins her longtime friend, former law school classmate and firm partner Will Gardner, who is interested in rekindling their former relationship.
The firm's top litigator and other partner, Diane Lockhart, likes Alicia's work and her connections so she and Will award her with a full-time associate position following a trial period.
Alicia beat out Cary Agos, a clever young attorney who takes a job in the state's attorney's office, now bitter and vengeful.
Alicia finds an ally and a friend in Kalinda, the firm's tough and mysterious in-house investigator.
Gaining confidence every day, Alicia transforms herself from embarrassed politician's scorned wife to resilient career woman, especially for the sake of providing a stable home for her children, 14-year-old Zach and 13-year-old Grace.
Now that Peter is back home and planning to run for office again with help from Eli Gold, his cunning image consultant, Alicia continues to redefine herself and her role in her family's life.
