Star Trek: Strange New Worlds season 3: Full cast list
Anson Mount as Captain Christopher Pike

The commanding officer of the USS Enterprise. Pike is portrayed as an empathetic and collaborative leader, in contrast to the authoritative version first introduced in the 1960s series. Star Trek: Strange New Worlds season 3 begins with Pike facing the Gorn threat and the potential loss of Captain Batel.
Beyond Star Trek, Mount is known for leading roles in Hell on Wheels, Marvel’s Inhumans, and Conviction, and he has voiced Batman in Injustice.
Ethan Peck as Spock

The science officer of the Enterprise, Spock, is a half-human, half-Vulcan officer known for his logical approach and inner conflict with emotion. Strange New Worlds explores a more emotionally open version of Spock before he becomes the stoic figure seen in The Original Series.
Ethan Peck has worked closely with the legacy of Leonard Nimoy's portrayal and made notable physical commitments, such as shaving his eyebrows to match the Vulcan look more accurately.
Beyond Star Trek, Peck is known for roles in 10 Things I Hate About You, Madam Secretary, and The Midnight Sky, and he voiced characters in the video game Halo 5: Guardians.
Jess Bush as Nurse Christine Chapel

A civilian nurse on the Enterprise, Chapel, returns while continuing her work in archaeological medicine. Star Trek: Strange New Worlds season 3 focuses on her relationships with both Spock and her future fiancé, Dr. Roger Korby. The series reimagines Chapel from her original depiction in The Original Series, placing greater emphasis on her independence, wit, and emotional complexity.
Known for her background in visual arts and modeling, Jess Bush previously appeared in the Australian series Playing for Keeps and competed on Australia’s Next Top Model.
Christina Chong as La’an Noonien-Singh

Chief of security aboard the Enterprise, La’an is a survivor of a Gorn attack that killed her family. Her character is shaped by trauma, survivor’s guilt, and a guarded demeanor, though over time she becomes more connected to the crew. As a descendant of Khan Noonien Singh, she faces discrimination and internal conflict about her legacy.
Season 2 introduced a romantic storyline with an alternate version of James T. Kirk, while Star Trek: Strange New Worlds season 3 sees her continue to confront her past and personal growth. Chong has also appeared in Doctor Who, Black Mirror, and Dominion.
Melissa Navia as Lt. Erica Ortegas

The Enterprise's helmsman, Ortegas, is a highly skilled pilot with a military veteran background. She is known for her quick wit and confidence in high-pressure situations.
Navia worked closely with the show's graphics and technical team to portray the act of piloting the Enterprise accurately. The character's name references Jose Ortegas from the original Star Trek pitch. In addition to her role in New Amsterdam, Navia has also appeared in Billions and Dietland.
Rebecca Romijn as Lt. Commander Una Chin-Riley / Number One

Serving as the Enterprise's first officer and second-in-command to Captain Pike, Una Chin-Riley, also known as Number One, continues her duties with renewed assurance after the events of her season 2 court-martial. The character, originally portrayed by Majel Barrett and unnamed in The Original Series, was given her full name in Strange New Worlds, which also confirmed her Illyrian heritage.
Her story arc has dealt with Starfleet's genetic modification laws and themes of identity and justice. Romijn is known for her role as Mystique in the X-Men film series and for starring in The Librarians, Ugly Betty, and King & Maxwell.
