Walter Koenig, Star Trek's Ensign Chekov, Dies at 90
The actor, who played the Russian navigator in the original series and subsequent films, passed away peacefully at his home.
Walter Koenig, best known for his role as Ensign Pavel Chekov in the original Star Trek series and its film franchise, died Sunday at his North Hollywood, California, home. He was 90.
Koenig's agency confirmed his death in a Facebook post on Monday, stating he passed away from old age and was with his daughter, Danielle, and niece. "Walter’s legacy extends far beyond the screen," the statement read. "Through countless convention appearances and interactions with fans, he shared his kindness, wit, and appreciation with everyone fortunate enough to meet him."
George Takei, who played Sulu in Star Trek, shared his grief on Facebook, recounting his friendship with Koenig that began in 1960. "My heart is heavy," Takei wrote. "Walter was more than Chekov. He was a writer, a teacher, a thoughtful man, and a loyal friend. To the fans who loved him for so many years, thank you. He loved you too."
Born in Chicago on September 14, 1936, Koenig was raised in New York City by Russian Jewish immigrant parents. He initially pursued pre-med studies at Grinnell College before transferring to the University of California, Los Angeles, where he earned a degree in psychology. A professor at UCLA encouraged him to pursue acting, leading him to study at New York's Neighborhood Playhouse.
Koenig's early television credits included appearances on "Combat!" and "The Untouchables." He also had a role on "General Hospital" before being cast as Ensign Chekov in "Star Trek" in 1967, joining the series for its second season.
In a 2013 interview with the TV Academy Foundation, Koenig recalled learning he had landed the role when a wardrobe assistant measured him for his costume. "And that’s the auspicious way I learned I was on 'Star Trek' and it was going to change my life," he said.
He continued with the series through its third season and reprised the role of Chekov in "Star Trek: The Motion Picture" (1979), "Star Trek II: The Wrath of Khan" (1982), "Star Trek III: The Search for Spock" (1984), and several subsequent films.
Koenig's other acting credits include roles in films such as "Raging Midlife" (2025) and the short "Lost Voyages: Phase II and the Rebirth of Star Trek" (2025). He also appeared as himself in "The Adam Project" (2022).
He married Judy Levitt in 1965, with whom he had a daughter, Danielle, and a son, Andrew, who died by suicide in 2010. Levitt passed away in 2022.
