- "From the moment your children are born, you worry what the world might do to them...but you never stop to think what you might do to them. That we could be our worst enemy."
- —Moira to Oliver Queen[src]
Moira was the wife of the late Robert Queen, the mother of Oliver Queen and Thea Queen, the grandmother of William, the ex-wife of Walter Steele, the ex-close friend/ex-lover/enemy of Malcolm Merlyn, the ex-friend of the late Frank Chen, and the old friend of Jean Loring and Jessica Danforth. After Walter was kidnapped by Malcolm, she became the new acting CEO of Queen Consolidated. In "Sacrifice", after Oliver convinces her to do the right thing, she held a press conference and confessed her involvement in a conspiracy to destroy the Glades and everyone in it, against her free will; in the press conference, she testified that the mastermind of this conspiracy was Malcolm. After this, she is arrested for conspiracy to commit murder. In "State v. Queen", Moira was released from prison, by Malcolm's help, and it was revealed that Thea is the daughter of Malcolm Merlyn. She was running for mayor of Starling City but was stabbed through her heart by Slade Wilson with his katana, in front of Oliver and Thea in his own mission of vengeance against Oliver.
Moira was born in 1964. She met and married a man named Robert Queen, who she had a son with, Oliver. At some point Moira met and became close friends with Malcolm Merlyn and Walter Steele. She also became good friends with Jessica Danforth.
Due to her husband constantly cheating on her, in retaliation Moira cheated on Robert with his best friend Malcolm, who was in grief over his wife Rebecca's death; the affair was brief but it resulted in her getting pregnant with his second child and only daughter, Thea.
Later on, Oliver got a girl, Samantha Clayton, pregnant. After a thorough investigation confirming the child is in fact Oliver's, believing this could potentially ruin Oliver's life, Moira went behind Oliver's back and did a compromise. She offered the girl two million dollars if she told Oliver she had a miscarriage and moved to Central City and never spoke to Oliver again, allowing both Oliver and her grandchild to have a bright future. Despite Samantha agreed to lie to Oliver, it is later revealed that she never cashed Moira's check, and she denied Moira access to her grandson, William, due to the former's hatred of her. Moira finds herself cannot seek legal battle against Samantha without Oliver and her family knowing the truth. During the Undertaking Moira went to Malcolm and tried to get out. Malcolm however slapped Moira's cheek.
In "Pilot", when her son returns, she goes to the hospital and is told by Doctor Neil Lamb that "the Oliver you lost, may not be the one they found". After Oliver is abducted, she voices concern over his safety and hires John Diggle to be his bodyguard. However, at the end of the episode, she is shown to be the one behind Oliver's abduction, after his arrival.
In "Honor Thy Father", she is first seen accompanying Oliver with the rest of her family and Tommy Merlyn to go to court to get Oliver legally resurrected. Later on, as Oliver is taken to his father's company, Walter and Moira try to convince Oliver that he needs to be the one to run the company though they do so unsuccessfully. After Oliver ditches his bodyguard Diggle once again, she expresses to Oliver that she lost him once and doesn't want to do so again, so she wants Diggle to accompany him when he goes out. As the episode ends she is seen getting into a limousine with an unknown man, it is here revealed that the ship Oliver and his father were on didn't shipwreck but was sabotaged by Moira and the unknown man, later revealed to be Malcolm Merlyn.
In "Lone Gunmen",
In "An Innocent Man", Moira is further questioned by Malcolm Merlyn, who points out to her that The Hood isn't going after the rich, but is actually going after the people on "the List". Later at some Quentin arrives with multiple police officers and arrests Oliver accusing him of being the Arrow.
In "Damaged", when Oliver is in the interrogation room Moira and Walter barge in and stop it while talking to Oliver about attorneys to use but Oliver wants Laurel. Though hesitant at first Moira then does ask Laurel but she declines but eventually decides to do so and Moira is present to see it in court, though Oliver isn't arrested he is put under house arrest. Furthermore, Oliver decides to have a house party much to Moira's concern. She is later interrogated by Malcolm who suspects Oliver of being the Hood because of the evidence but Moira assures him that he is not. Moira later visits Walter who tells her that he has found the remains of the Queen's Gambit and Josiah Hudson was killed trying to move the wreck but Moira tells him not to look any further into the matter. When Moira returns a gunman has attempted to kill Oliver and Moira openly blames Quentin for accusing Oliver publicly and making him a target, Oliver is then cleared of charges when Quentin states that the Hood was seen elsewhere at the time and Moira apologists for his family's troubles but calmly tells him to get the @#!*% out. She later visits Malcolm, knowing that he sent the gunman to kill Oliver and had Josiah killed, and threatens to destroy everything Malcolm was worked toward. Later Walter leaves but doesn't know when he'll be back much to Moira's concern.
In "Muse of Fire",
In "Year's End",
In "Trust but Verify",
In "Betrayal", she burned the book that held "The List". She later had a brief meeting with Malcolm Merlyn which Diggle eavesdropped on and recorded, learning about the Undertaking that they have planned.

In "Salvation", when Malcolm seemed on the verge of being able to determine who paid the Chinese Triad, Moira betrayed her co-conspirator Frank Chen and set him up to be killed by Malcolm so that Malcolm would not discover she was the one behind the assassination attempt. She then begged that the life of Frank's daughter be spared, and Malcolm, as the Dark Archer, agreed.
In "Home Invasion", Moira welcomes Tommy and Laurel into her home, while they are hiding from the assassin who is trying to kill the child they are watching over. When she is talking to Laurel later, she admits that she liked who Oliver was when she was dating him.
In "The Undertaking", during flashback sequences, Robert confides in Moira about the Undertaking and she tries to convince him not to do it. In the present, she is online shopping with Thea when Oliver comes in to tell them that Walter was dead. She goes straight to Malcolm and is furious with him for having Walter killed. Malcolm calls someone to turn on the camera, and she is shown that Walter is actually alive. Oliver hears her admit that she was part of the Undertaking.
In "Darkness on the Edge of Town", Walter is distant from Moira as he realizes that she was behind his kidnapping. He files for divorce soon after. Oliver later talks to her, and they are both kidnapped by John, disguised as The Hood. She confesses her involvement in the Undertaking, after John hits Oliver multiple times.
In "Sacrifice", Oliver convinces Moira that she had to do something. She holds a press conference where she admits her culpability in the Undertaking out of fear for her family's life. After a statement in front of the Starling City press, she is arrested for conspiracy to commit murder.

Thea dumps Roy but does not reveal the real reason until Moira contacts Roy and Thea from the prison, bringing them together again.
In "State v. Queen", Moira is put on trial for her involvement in the Undertaking and the resulting deaths of 503 people in the Glades. Laurel Lance tries to dissuade Moira from testifying in her own defense after discovering ADA Adam Donner has a "trump card" that will swing the jury against her. Moira later confesses to her children that Donner's trump card is the fact that she once had an affair with Malcolm Merlyn.
During the trial, Moira decides to take the witness stand. Laurel cross-examines her and reveals the affair with Merlyn in open court. However, the jury finds Moira not guilty on all counts despite the apparent strength of the prosecution's case. After she is released, Moira is taken by her driver to meet a very alive Malcolm Merlyn, who informs a stunned Moira that it was he who manipulated the jury to get her acquitted, and that he knows Thea is his daughter. It is implied that hers and Malcolm's affair was not as brief as she claimed it to be.

In "Tremors", she has dinner with Walter and one of his colleagues, who try and convince her to run for mayor against Sebastian Blood, whose policies they believe would threaten the corporations of Starling City. At first, she believes both of them are in way over their heads as she doesn't believe anyone in Starling City would vote for her as a result of the Undertaking. However, Walter later points out that 43% of the people in Starling City do not blame her for the Undertaking, and that everyone loves a redemption story. After talking with Thea, who agrees with Walter and believes that Moira would make a great mayor, Moira soon agrees to run, but tells Walter (who is revealed to be aware that Thea is not Robert's daughter), that her OBGYN knows about Thea's true parentage and must be silenced throughout her campaign.
In "Heir to the Demon", Moira is confronted by Felicity, who has figured out Thea's true parentage. Manipulating Felicity's feelings towards her son, Moira convinces her not to tell Oliver the truth.
She kicks off her mayoral campaign, with Oliver and Thea by her side. Later she then meets with Sebastian Blood, who tells her to get out of the mayoral race; she refuses and warns Blood not to underestimate her.
An angry Oliver later meets with Moira, furious that she has hidden the truth about Thea from everyone. Moira pleads that she was doing it to protect their family, but Oliver declares that their relationship is over.
Moira also appears in a flashback sequence, visiting Quentin and Laurel Lance in order to tell them that Sara was on the Queen's Gambit when it sank.
In "The Promise",
In "Seeing Red", she is shown having an interview about her mayoral campaign. Thea interrupts the interview to states that Moira can no longer use Verdant for her campaign rally. Moira reminds Thea that she signed a contract, further alienating her daughter. Moira's campaign manager advises her that Moira cannot be a candidate and a mother at the same time. Later, she is shown telling Sebastian Blood that she is dropping out of the mayoral race, even though she is ahead in the polls. Sebastian requests an explanation, and Moira replies it's because her family needs her. Later, she is getting ready for her speech at the rally. Oliver comes in and demands to know why she is dropping out. She says that she needs to be with Thea. Oliver says that she should show Thea that she is a good person by changing Starling City as mayor. Moira then reveals that she has known that Oliver is the Arrow after the events of the Undertaking, and says she has never been so proud of him. She makes her speech and decides to keep running for mayor. Then, she flees along with everyone else in Verdant when Roy Harper comes in. Later she is shown in a limousine with Thea and Oliver. Thea says that Oliver and Moira should tell the truth. Moira is about to reveal something to Thea and Oliver about Malcolm Merlyn (presumably that he is still alive) when the car is hit. Moira is then shown tied up with Thea and Oliver, and Slade Wilson asks Oliver to choose which one of them should be killed. Moira volunteers herself, stating that both of her children will live. Slade states that Moira has true courage, and that it is a shame that it wasn't passed on to Oliver, then he stabs Moira in the chest with his sword.
Throughout the episode, Moira appears in a flashback sequence from seven years ago. Oliver finds out that he has gotten a girl pregnant, and Moira resolves the situation by giving the girl two million dollars to never contact Oliver again and say that she lost the baby.
Moira loved both of her children very much, although she made mistakes, she was also not afraid to die for her children, however, her constant lies was what eventually destroyed her relationship with Oliver and Thea. While Moira did not live to see this; Thea ultimately matured even more after her death. Ironically, the one who helped her mature is Malcolm Merlyn; the very person that she failed to keep away from Thea.
A year and a half later, her friend Jessica Danforth decided to run for mayor until her daughter Madison Danforth was kidnapped by Lonnie Machin, her daughter was saved by Oliver and she decided to step down for her daughter's safety. Oliver was inspired by the words of Quentin and Jessica, he then decide to follow in his mother's footsteps and run for mayor.
Oliver eventually learns that Moira kept his son William with Samantha Clayton a secret from him 9 years later, which complicating his life instead of making it better as he does want to be a father, and thus proving to be another one of her mistakes; as Oliver becomes very angry that his late mother deprived him of his own child and how it could risk his relationship with Felicity Smoak.
Because of her manipulative and lying traits, Moira was never allowed access to her grandson William, as Samantha correctly believe the latter would be a bad influence on her son; this makes Samantha a foil to Moira in parenthood as the former has proven to be a good mother to her own child without resorting to manipulation and constantly lying to her son.
Moira was oftentimes ruthless and immoral, in an ends-justify-the-means sense. She had her own son kidnapped, but tried to justify it as doing so to prove he knew nothing about the Undertaking, and to save his life. She attempted to have Malcolm Merlyn killed, so that she would be out from under his thumb, she and her children would be safe, and to prevent the deaths of innocent thousands. When the attempt failed, she betrayed her co-conspirator and old friend, Frank Chen, to avoid her own implication and so she and her children would not be killed. Malcolm, as the Dark Archer, killed Frank. Despite evident and prevalent flaws, it should be noted that Moira convinced the Dark Archer to spare Frank's daughter, however she disregarded the fact, that Frank was Amanda only family left alive, and this did not stop from him from orphaning Amanda.
As a parent, Moira was a poor one, always giving her children too much space. After receiving encouragement from the reformed Oliver, Moira tried to be a better parent, trying to ground Thea for breaking into a store and underage drinking.
In Season 2, Moira showed guilt and remorse for her involvement in the Undertaking, for being partly responsible, the deaths of 503 including Tommy, she almost went through with the assistant district attorney, agreement, just so her children would not find out about her affair with Malcolm, and that Malcolm is Thea's biological father, when Moira discovered that Malcolm is still alive, she reveals he is alive to Ra's al Ghul.
Moira had failed time and again to learn from her mistakes, as her constant lies was what eventually destroyed her relationship with her children.
Moira eventually reveals to Oliver that she knows he is the Arrow. She, Oliver and Thea are kidnapped by Slade Wilson. Slade then makes Oliver choose who to kill the same way Ivo did for Shado and Sara. Slade decides to kill Thea but, instead Moira chooses to sacrifice herself. Slade kills Moira with his sword into her heart, leaving her to die.
