Dolores Abernathy is portrayed by Evan Rachel Wood and is one of the series' central characters. She is the oldest host still working in the park. Dolores is a rancher's daughter who discovers her entire life is an elaborately constructed lie. Her aesthetic drew influences from Andrew Wyeth's painting Christina's World as well as Lewis Carroll's Alice.
Maeve Millay is portrayed by Thandie Newton. Maeve is a host who acts as the madam of Sweetwater, the largest town in Westworld. Through Dolores, she becomes aware that her life has been a lie, and recalls memories of raising a daughter before she was killed by a guest. She is able to "wake up" within the Mesa, where she coerces technician Felix to alter her programming, making her more intelligent and able to control other hosts with her voice, and befriends Hector and Armistice to help protect her. At the end of the first season, Felix is able to help her leave the Westworld park. However, she is drawn back on the promise of finding her daughter, even though she is aware this daughter was from a previous narrative. The second season focuses on her attempts to locate her daughter.
Bernard Lowe is portrayed by Jeffrey Wright. He is the head of the Westworld Programming Division and creator of artificial people. Later in the plot, he is revealed to be a host under Ford's control, made in the image of Westworld's co-creator, Arnold Weber, and based on Ford's and Dolores' memories of him. "Bernard Lowe" is an anagram of "Arnold Weber".
Arnold Weber is portrayed by Jeffrey Wright. He was the co-founder and developer of Westworld alongside Ford. Arnold had come to anthropomorphize his already life-like creations, and made it his goal to bring the Westworld hosts to full sentience, with Dolores as his test bed. When the park was nearing opening, 30+ years before the "present day" of the show's timeline, Arnold had not yet been able to succeed in this, having concluded that the path to sentience was not simply linear. Having failed to achieve his goal, and believing that the intended function of even non-sentient hosts was still tantamount to them being misused by guests, he instructed Dolores to kill all the other hosts, then kill himself and herself, hoping this tragic event would prevent the park from opening.
Theodore "Teddy" Flood is portrayed by James Marsden. He is a host in the role of a gunslinger who returns to Sweetwater looking to rekindle his relationship with Dolores.
Armistice is portrayed by Ingrid Bolsø Berdal. Armistice is a host who is a brutal and ruthless bandit and a member of Hector Escaton's gang.
Ashley Stubbs is portrayed by Luke Hemsworth. He is the head of Westworld security, charged with monitoring host and human interactions and ensuring the safety of the guests. At the end of the second season, it was revealed that he is a host and he is well aware of the implantation of Dolores' consciousness into the Charlotte-body replica, but he let her escape the park since he is "responsible for every host inside the park". 
Theresa Cullen is portrayed by Sidse Babett Knudsen. She is Westworld's terse operations leader, responsible for keeping the park from sliding into unscripted disarray. She later forms an alliance with Charlotte Hale and Delos to conspire against Dr. Ford and remove him from power. Ford orchestrates the death of Theresa soon after by having Bernard murder her.
Lee Sizemore is portrayed by Simon Quarterman. He is Westworld's narrative director, whose artistic temperament aggravates his co-workers. After the host uprising, Sizemore accompanies Maeve on her journey to find her daughter.
Clementine Pennyfeather is portrayed by Angela Sarafyan. She is a host who works for Maeve and is one of Westworld's most popular attractions. When she is decommissioned, her role is given to another host (portrayed by guest actress Lili Simmons in seasons 1-2) and the lobotomised Clementine is put into cold storage.
Elsie Hughes is portrayed by Shannon Woodward. A rising star in the Programming Division tasked with remedying odd behavior in the park's hosts. She was briefly knocked out by Bernard (under the control of Ford) as she 'got in the way' of Ford's plan. In the second season, she was shocked to learn Delos' secret guest-data collection project while also learning that Bernard is a host. Fearing that Bernard is still under the control of Ford even after Ford has died, she attempted to negotiate with Charlotte to keep Bernard within the park, in exchange for her silence on the project - instead, Charlotte kills her ruthlessly.
William, also known as the Man in Black or Billy, is portrayed by Jimmi Simpson as a young man and by Ed Harris as an elderly man. He was a reluctant first-time visitor to Westworld, joining his future brother-in-law, Logan Delos. Initially dismissive of the park's more lascivious attractions, he slowly uncovered a deeper meaning to the park's narrative. He later became a rich, sadistic Westworld guest searching for a "deeper level" in the park. Outside of the park, he is married to Juliet, the daughter of Delos corporation creator James Delos, and has a daughter Emily. He is also a board member of Delos, and has achieved prominence as the owner of a medical foundation. His obsession with the Westworld park, and the dark acts he committed against hosts while in it, led to Juliet's suicide, which he blamed himself for. While he once had a vision of using host bodies to house the minds of humans—such as trying to help his deceased father-in-law gain immortality—he later expresses regret at having allowed the project which he characterises as his "greatest mistake". His motives are often unclear, at once seeking to destroy Westworld whilst simultaneously rejecting the possibility of personal redemption.
Robert Ford is portrayed by Anthony Hopkins, as a young man by Paul Fox and Paul Riley Fox, as a child by Oliver Bell, and by Gina Torres when disguised as Lauren. He is the founder and creative director of Westworld, who has near-total control over the park's functions and the hosts. It is eventually revealed that he has been orchestrating the hosts' uprising with his new and final park narrative, "Journey into Night". Similar to his old partner Arnold, he wanted hosts such as Dolores and Maeve to achieve consciousness and break free of the park. At the end of the first season, he seemingly allows himself to be killed by Dolores out of her own free will. However, he is revealed to have uploaded his consciousness to the park's "hive mind" data center, from where he has been guiding William through various hosts (portrayed by Oliver Bell, Giancarlo Esposito, and Izabella Alvarez) and continuing to orchestrate the uprising. After reuniting with Bernard, he transfers himself into his former partner's control unit and takes control of his body (portrayed by Jeffrey Wright). Finding an incapacitated Maeve, he encourages his "favourite" host and unlocks her "core" permissions. At the end of the second season, Ford allows himself to be deleted by Bernard so that he can regain his free will, dying a final time. Upon Bernard attaining consciousness, a hallucination of Ford bids him a final farewell.
Logan Delos is portrayed by Ben Barnes. Logan, a member of the Delos Corporation, led the company's investment into Westworld some thirty years prior to the present events. Shortly after this, he brings his soon-to-be brother-in-law William to visit Westworld and tries to have him enjoy the park's more hedonistic offerings, but William comes to other conclusions about how to take advantage of Westworld for financial gain. James Delos, Logan's father, became dissatisfied with Logan's investment in Westworld until William suggested the lucrative opportunities they could pursue, such as selling a form of immortality by transferring human minds into host bodies. James subsequently named William, instead of Logan, as successor to the Delos company, and Logan entered a deep depression, eventually killing himself by overdose.
Lawrence Pedro Maria Gonzalez is portrayed by Clifton Collins Jr.. He is a host with a reputation as a charming but lethal outlaw with a knack for maneuvering and negotiating the various criminal elements of Westworld. In the past, the host has played the El Lazo role. Lawrence (and possibly his version of El Lazo) has a deep love for his wife and daughter, which has an impact on his interactions with the young William and his older Man in Black. In the second season, he becomes a traveling companion of the Man in Black during the early days of the host's rebellion.
El Lazo is a host role formerly filled by Lawrence, portrayed by Clifton Collins Jr.. In the season 1 flashbacks, the host El Lazo encountered Logan, William and Dolores in Pariah. Sometime later, the role of El Lazo was assigned to another host. In the second season, the new El Lazo is portrayed by guest actor Giancarlo Esposito.
Charlotte Hale is portrayed by Tessa Thompson. Delos' executive director of the board overseeing Westworld. She seeks to smuggle Ford's hosts' data out of Westworld on behalf of Delos via Peter Abernathy's control unit and allow the company to wrestle control of the park away from him. Her plan turned awry when Ford had successfully lead to the hosts' uprising, led by the awakened Dolores. She proved to be a ruthless director as she mercilessly kidnaps Peter for his control unit and kills Elsie in exchange for her silence. She was eventually killed by Dolores, who was implanted into an exact Charlotte-body replica by Bernard, in retaliation of Elsie's murder.
Peter Abernathy is portrayed by Louis Herthum. He is a host and Dolores's father. His programming falters when he finds a picture of Times Square that a guest has dropped, forcing the park to decommission him and replace him with a new Peter Abernathy host (portrayed by recurring actor Bradford Tatum in the first season). The original Peter host is put into cold storage, but then is used by Charlotte Hale to try to smuggle intellectual property out of the park. Once the hosts revolt, the Peter host goes missing, and he becomes the target of Charlotte and her Delos security forces, as well as Dolores who considers him her real father. Charlotte recovers Peter but is unable to extract the data before Dolores finds him; after a tearful goodbye knowing that his host system is failing, Dolores cuts the control core, containing the encrypted data, out of his body.
Emily, also known as Grace, is portrayed by Katja Herbers and as a child by Adison LaPenna. She is William's daughter, and is formally introduced in the second season, seen as an adult guest at a Delos park themed on the British Raj, one of the six (or more) parks on the Delos-controlled island. When the hosts in the Raj start to exhibit the same revolt as the Westworld ones, Emily escapes into Westworld and finds William, traveling as the Man in Black, during his mission. She resents her father for past actions that contributed to her mother's suicide. She convinces a sentient Akecheta to give him her wounded father, promising the host that she shares his goal of inflicting pain on the Man in Black. However, in trying to convince her father to come with her for medical help, William still believes she is a host, part of Dr. Ford's game, and kills her. In the far future, a host version of Emily is seen to be giving a Fidelity test to a human-host hybrid version of William.
Akecheta is portrayed by Zahn McClarnon. He is a host and a Ghost Nation elder. He has a fearsome reputation in the park, leading raiding parties and taking hosts prisoner. It is subsequently revealed that he started to achieve sentience decades earlier, purposefully avoiding death for many years and accumulating knowledge of the "other world". Unlike Dolores and Maeve, he has not been manipulated into it by Ford, who nonetheless has followed Akecheta's progress with interest. His raiding parties have been rescue attempts aimed at securing hosts that he intends to lead out of Westworld. Zahn McClarnon is credited as a main character in "Kiksuya".
