Walter Koenig, the actor who played the Russian navigator Pavel Chekov on the original Star Trek, has died at the age of 90. He died of natural causes on Sunday, October 25, 2026, at his home in North Hollywood, his representative said. TVLine reported that his daughter and niece were with him.
His death leaves William Shatner and George Takei as the last surviving members of the original series’ main cast.
Joining the Enterprise
Koenig joined Gene Roddenberry’s series at the start of its second season in 1967 and appeared in 36 episodes before the show ended in 1969. Producers wanted a young crew member who would appeal to the same audience as Davy Jones of The Monkees, and Koenig later said his fan mail came mostly from children aged 8 to 14. “I got hundreds and hundreds of letters, the third most after Bill and Leonard,” he recalled in a 2013 interview with the TV Academy Foundation.
He played Chekov again in Star Trek: The Motion Picture (1979) and the five original-cast films that followed, ending with The Undiscovered Country (1991), and once more in Star Trek Generations (1994). He was nominated by the Academy of Science Fiction, Fantasy and Horror Films for The Wrath of Khan and The Voyage Home. In 2023 he voiced President Anton Chekov in an episode of Star Trek: Picard.
Babylon 5 and writing
A heart attack and quadruple bypass in 1993 cost him an early role on Babylon 5, but creator J. Michael Straczynski later wrote the part of the Psi Cop Alfred Bester for him. The character became central to several of the show’s storylines.
Worried about finding acting work after Star Trek was cancelled, Koenig turned to writing. He wrote episodes of Land of the Lost, Family and The Powers of Matthew Star, an episode of Star Trek: The Animated Series, and the 2010 science-fiction film InAlienable. He published the memoir Warped Factors: A Neurotic’s Guide to the Universe in 1998 and expanded it as Beaming Up and Getting Off in 2020.
Early life
Koenig was born in Chicago on September 14, 1936, the son of Lithuanian immigrants, and grew up in Manhattan. He studied pre-med at Grinnell College in Iowa before moving to UCLA to study psychology. An acting class there led him to the Neighborhood Playhouse in New York, where his classmates included James Caan and Christopher Lloyd. Before Star Trek he appeared on General Hospital, Mr. Novak and The Alfred Hitchcock Hour.
He kept working into his final years and this year won best actor at the Independent Shorts Awards for the short film Mr. Fleischmann.
Tributes and family
“Walter and I met on the bridge of the Enterprise in the 1960s, and we stayed friends for nearly six decades,” George Takei wrote on Instagram. “Walter was more than Chekov. He was a writer, a teacher, a thoughtful man, and a loyal friend.”
Koenig was married to the actress Judy Levitt from 1965 until her death in 2022. Their son, the actor Andrew Koenig, died in 2010. He is survived by his daughter, the actress and screenwriter Danielle Koenig.
