Main

* Tatiana Maslany as a number of clones (Sarah Manning, Beth Childs, Katja Obinger, Alison Hendrix, Cosima Niehaus, Helena, Rachel Duncan, Jennifer Fitzsimmons, Tony Sawicki, Krystal Goderitch, Veera "MK" Suominen), all born in 1984 to various women by in vitro fertilisation. Their creation was referred to as Project Leda. The series focuses on Sarah Manning, a small-time con woman and orphan who is the only clone to have a biological daughter. (All clones were presumed to be sterile before Sarah was discovered, with one of the original scientists revealing that the clones, as 'prototypes', were all designed to be sterile, and it is also revealed in season 2 that Helena is also able to conceive given her origin as Sarah's specific twin.) Other clones include Elizabeth "Beth" Childs, a police detective whose suicide at the start of the series leads Sarah into the conspiracy; Alison Hendrix, a soccer mom who tries to be the perfect housewife, but suffers from pill and drink addiction as well as jumping to conclusions; Cosima Niehaus, a lesbian graduate student studying evolutionary developmental ("evo-devo") biology who researches the clones' biology; Helena, the twin sister of Sarah, a fanatic assassin trained by the Proletheans who has suffered severe abuse throughout her life; Rachel Duncan, an executive at the Dyad Institute, who was raised knowing that she is a clone from childhood. Maslany also voiced the scorpion, called Pupok, that speaks to Helena in her hallucinations in Season 3.
* Dylan Bruce as Paul Dierden, an ex-military mercenary, who was blackmailed into being Beth's monitor under the guise of being her boyfriend. Following the discovery of Beth's death and Sarah's impersonation of her, he chooses to continue trying to protect Sarah, calling it his job. The two continue a sexual relationship. However Dyad still holds his past over him and makes him Rachel's new monitor, with Rachel forcing him into a sexual relationship with her. In the season 2 finale it is revealed he is still in the military and was a double agent from Project Castor spying on Dyad and Project Leda. Paul checks on Rudy and Seth's cognitive functions and orders them to return to the military base. He also warns Cal that Sarah needs to stop investigating Castor for her own safety. Paul begins to investigate Dr. Coady at the military compound, and he finds that she has been illegally sterilizing common women with the contagious Castor disease in order to collect data and potentially produce a deadly biological weapon. Paul helps Sarah escape the military compound, and he confesses that, even though he never loved Beth, his love for Sarah was genuine. During their escape, Miller stabs Paul several times to stop him from fleeing. Paul breaks Miller's neck and then sends Sarah away on her own in an attempt to destroy Coady's research in order to prevent the development of the weaponry. When Coady and Rudy rush to retrieve Coady's scientific work, they confront Paul who is attempting to stop the two from reclaiming Coady's unethical scientific data. Coady shoots Paul multiple times in the chest who then releases a grenade while he is dying. Rudy reacts quickly to the danger, allowing him and Coady a few extra seconds of escape before Paul's grenade detonates. (seasons 1–4)
* Jordan Gavaris as Felix "Fee" Dawkins, Sarah's gay foster brother and confidant; when none of her sisters are available, he acts as Sarah's backup. During childhood, they were quite close, but she often abused him for amusement; they are still close as adults. He identifies as a modern artist, but moonlights as a prostitute. He is the first person Sarah confides in about the existence of clones, and has developed his own friendship with Alison in particular while helping her cope with the stress of her existence as a clone. During Seasons 2 and 3, Cosima stays with him, due to her declining health.
* Kevin Hanchard as Detective Arthur "Art" Bell, Beth's police partner. He cares for Beth and tries to guide her through tough times even when she is dead as he unknowingly is helping Sarah as Beth. After he learns of Beth's stolen identity and death he decides to side with the clones over the police department, carrying out off-the-books research for them. In Season 3, Sarah figures out that Art was in love with Beth, but wasn't able to bring himself to tell her. It turns out Art was close enough to Beth that she called him for help prior to her suicide to explain about the clones; however, Art dismissed the call, believing Beth was high on her prescription drugs.
* Michael Mando as Victor "Vic" Schmidt, Sarah's abusive, drug-dealing ex-boyfriend. Vic is something of a nosy idiot, as he cannot accept facts when told to his face (such as Sarah hating him and never wanting him around) and investigates anything suspicious. After being tricked by Felix into thinking Beth's corpse was Sarah, Vic grieves; however, he later meets Alison, thinking she's Sarah. He invites himself to Alison's potluck, thinking Sarah is pulling a scam; however, Paul manages to scare him off. He becomes a police informant for Angie and under her orders he befriends Alison at rehab; Angie would erase his criminal record in exchange. He is later intimidated by Donnie to stay away from the Hendrix family. (regular season 1; recurring season 2)
* Maria Doyle Kennedy as Siobhan Sadler, Sarah's and Felix's Irish foster mother; they call her "Mrs. S.". She fell in love with and married John Sadler at a young age, befriending his group of freedom fighters – the Birdwatchers. After John was murdered in a fight with her mother back in '78, Siobhan started a new relationship with Carlton. She acts as guardian to Sarah's daughter Kira while Sarah is away. She is shown to be intelligent and resourceful, hiding Sarah for years and protecting her and Kira. Mrs. S used her network to hide Ethan Duncan and find Sarah as a child, claiming to have protected her from Dyad Sarah's whole life. Mrs. S makes a deal with Paul and the military to work with them and abduct Helena in exchange for a way to help Sarah and Kira. She eventually is forgiven by both sisters and is stunned as everyone else to learn that the genetic original for both clone lines is her mother Kendall Malone. Biologically speaking, Siobhan is Sarah's niece and that would make Kira her cousin. Siobhan later has her mother sent to Iceland, where Cal and Kira are hiding out. After Kendall is murdered by Marty Duko, a vengeful Siobhan eventually kills him. In the final stages of the clones' war with Neolution, Siobhan persuades Rachel to double-cross her lover Ferdinand, leading to a confrontation in which Siobhan and Ferdinand killed each other.
* Evelyne Brochu as Dr. Delphine Cormier, Cosima's monitor, girlfriend, and fellow scientist. She is torn between her job at Dyad and her love for Cosima. After finding out about Cosima's illness she works with her in the Dyad to try to find a cure. She is promoted to the public leader of Dyad after Leekie's death and unintentionally helps Rachel kidnap Kira. Rachel then bans her from working with clones and tries to send her away to Frankfurt. However, Marion promotes Delphine to take over Rachel's position and Delphine enacts her revenge on Rachel. Delphine returns to Dyad, supposedly after learning that Sarah was kidnapped and has been missing for five days, but it is later revealed that her jealousy has led her to spy on Cosima and Shay's relationship, photographing and videotaping the two on their various dates. Delphine interrogates Shay, believing her to be the Castor mole. She is about to begin cutting Shay when Cosima calls to inform her that Gracie admitted to being the Castor mole. Delphine finds out that Dr. Nealon replaced Rachel with an induced Krystal and sent her to Vienna. She confronts him in an enclosed room, and he reveals that Rachel now belongs to Neolution, the group that he has been working for all along, attempting to procure the Leda and Castor original genomes for scientific advancement. Delphine calls for the guards to take Nealon away, but she receives no responses, and Dr. Nealon suddenly attacks her as he bleeds from the mouth. He leans over her, spilling blood onto her face, as a regurgitated worm spills from his mouth. Delphine shoots Nealon before the worm can reach her. As he dies, he proclaims that Delphine will be dead before morning. Delphine confronts Shay to apologize and tells her that she is giving Cosima permission to reveal everything to Shay, stating that the two are right for each other. She then visits Cosima at ''Bubbles'', discreetly saying goodbye to Cosima and the other Leda clones. Delphine parks her car in a parking garage and is followed by unseen pursuer. Delphine asks "what will happen to osima" and receives no response; instead, the pursuer shoots Delphine, whose death is implied but not seen. Krystal confirms in season 4 that Delphine was picked up, alive, by after being shot. She has been on the Island in the north this whole time after being spared by P.T. Westmorland, she reunites with a hypothermic Cosima, and then proceeds to undress to share body warmth with her in the patient bed located inside of one of the houses on the Island. (recurring seasons 1 & 4–5; regular seasons 2–3)
* Ari Millen as a number of male clones (see here) – the result of a sister project to Project Leda: Project Castor, a top-secret military program. Unlike their Leda counterparts, the Castor clones have always been aware of what they are, being raised together by the US military; their caretaker was Virginia Coady, who they refer to as Mother. They suffer a mental defect, which basically turns their brains to, quoting Scotty, "Swiss cheese" after set amount of time; unfortunately the defect is also an STD, which sterilizes women. Coady studies this, often sending Rudy off on leave to infect new test subjects. The first Castor clone to be introduced to the viewers is Mark Rollins, coming off as a homicidal Prolethean, before being exposed as an undercover Castor agent; he marries fellow Prolethean Gracie Johanssen after running away from the Prolethean farm, wanting a normal life with her before his defect kills him. Other major Castor clones includes the menacing scarefaced Rudy, the tormented Seth, the crippled Miller and the Neolutionist Ira. All the Castor clones are now deceased, with Mark, the last, executed by Coady. (recurring season 2; regular season 3–5)
* Kristian Bruun as Donnie Hendrix (né Chubbs), husband to Alison Hendrix. He was once Alison's monitor, working for Dyad. His and Alison's marriage was strained for a long time, especially after Alison cornered him and tortured him to find out if he was a monitor or not. He lied, and they reconciled. However, she then found out the truth: that he really was a monitor but was unaware of his true purpose and that Alison was a clone. He then cornered his boss, Dr. Leekie, in his car and killed him with an accidental pistol shot to the head. He fled back to Alison, begging her to help him do away with the body. They buried Leekie under their garage. This "bonding" helped to jump-start their relationship, giving it newfound passion, trust, and happiness. In season 3, he got fired after telling his boss Susan Teller that she was a bitch, something he found "frickin' glorious". He and Alison later briefly sold drugs for Pouchie, and got the Hendrix family soap store Bubbles from Ali's mother. Helena comes to live with them, and Donnie comes to see that she means well; he even helps find her boyfriend as a "thank you" present. After Pouchie's niece threatens Oscar and Gemma, Donnie is left with all the drug lord's money after Helena murders them to protect the children. (recurring seasons 1–2; regular season 3–5)

Five years later, Duncan returned to her out of grief to confess his true motivations for harvesting her DNA. He divulged his utilization of her DNA in order to produce a line of clones, and informed her of a female clone that had been lost in the foster system – Sarah Manning. Kendall managed to bring Siobhan and Sarah together due to her being a "regretful mother", in order to give Siobhan a piece of herself that is better than the person she turned out to be.

Clones

By the end of the first season, 10 clones are revealed. They are of various nationalities and stations in life. Additional clones are revealed in the second season, including Jennifer, who died from the same respiratory illness that affected Katja and Cosima. In episode 8 of season 2, Tony, a transgender clone is introduced. In the season one finale, Cosima discovers each clone has a different DNA tag based on ASCII coded basepairs. In addition to the identification code is the text "THIS ORGANISM AND DERIVATIVE GENETIC MATERIAL IS RESTRICTED INTELLECTUAL PROPERTY" followed by a series of patent numbers. Sarah is given a photograph whose caption suggests that the cloning project that produced her was called "Project Leda". In the season 2 finale, Charlotte, an 8-year-old clone with a leg disability, is introduced. At the start of Season 3 a non self-aware clone, Krystal, was almost kidnapped by the military. In Season 3 episode 8, a Polish clone is revealed to have recently died from the clone illness.

Season 2's finale reveals that the military carried on with a male cloning project called Project Castor, which created Mark (the Prolethean), Miller (the soldier clone), Rudy (a male clone held in the home of Marion Bowles), Seth (a mustachioed clone) and Parsons a clone kept barely alive by the military to study the cognitive defect. All of the Project Castor clones are self-aware of their clone nature and were raised together in a military-like environment.

In the Season 3 premiere it is revealed in 2006 Ferdinand of Topside was involved in the execution of six self-aware Project Leda clones in the Helsinki area. All were believed to be dead within 24 hours with another 32 people killed as collateral damage. Comics depicting the event would later clearly place it during 2001.

In the third episode of Season 3 it is revealed the originals for Projects Leda and Castor were brother and sister, making all the clones genetic siblings.

It is also revealed the DNA of the original Castor donor was stolen by Henrik Johanssen who wanted a son. This created Abel Johanssen who died as an infant.

The Castor and Leda original genetic source is revealed at the end of season three. It is Siobhan's mother, Kendall Malone, a genetic chimera who provided DNA for both the Leda and Castor lineages of clones, explaining the clones' relationship as genetic brother and sister.

In August 2015, at the conclusion of the ''Orphan Black'' comic book, a survivor of Helsinki was revealed: Veera Suominen. She will star in her comic series starting in November 2015 called ''Orphan Black: Helsinki'' and then appear in Season 4 of the show in 2016.

In March 2016, the new Castor clone Ira was revealed on the website for the show.

The seventh episode of Season 5 mentions a Leda clone, Lisa Glynn, in Rachel's childhood flashback and reveals another, Miriam Johnson, in young adulthood. Miriam was a homeless artist sick with the Leda defect; Rachel arranged her death so research into the illness could progress. The ninth episode of the season shows an unnamed Leda clone praying in a church, the first one Helena killed.

The final episode of the series reveals there are 274 Leda clones in the world. Stephanie Loyd and Gillian West are mentioned directly while other names are seen briefly on a list. The final clone of the series is Camilla Torres, seen being cured by Delphine.
