LOS ANGELES, October 26, 2026 – Walter Koenig, the actor who played navigator Pavel Chekov in the original “Star Trek” television series and seven “Star Trek” feature films, has died in Los Angeles at the age of 90.
Variety confirmed that Koenig died on Sunday, and the entertainment publication shared the news on X. His representatives said he died of old age at his home in North Hollywood, surrounded by his daughter and niece.
“Today we mourn the passing of Walter Koenig, whose talent, warmth, and unforgettable performances left a lasting mark on generations of fans around the world,” his representatives said in a statement. “Thank you, Walter, for the memories, the inspiration, and for boldly going where few have gone before.”
The statement noted that he remained active late in life, most recently winning the Platinum Award for Best Actor at the 2026 Independent Shorts Awards for the short film “Mr. Fleischmann”.
George Takei: ‘Keep navigating a steady course’
Fellow “Star Trek” star George Takei, who played helmsman Hikaru Sulu, paid an emotional tribute to his longtime friend, in remarks highlighted by Variety on X.
“My heart is heavy. Walter Koenig, our Ensign Pavel Chekov, passed away early today. Walter and I met on the bridge of the Enterprise in the 1960s, and we stayed friends for nearly six decades,” Takei wrote. “When Brad and I married in 2008, Walter stood beside us as our best man.”
Takei noted that Koenig turned 90 on September 14, the same day he and husband Brad Altman marked their 18th wedding anniversary. “Walter was more than Chekov. He was a writer, a teacher, a thoughtful man, and a loyal friend,” he wrote. “Rest well, my dear friend. Keep navigating a steady course.”
From the Enterprise to ‘Babylon 5’
Koenig’s Chekov, a brash young Russian-born navigation officer, was brought into the original series to appeal to teenage viewers, with a hairstyle that recalled the Monkees’ Davy Jones. The character later took centre stage in 1982’s “Star Trek II: The Wrath of Khan”, widely regarded as the finest of the franchise’s films. Koenig also wrote the “Star Trek: The Animated Series” episode “The Infinite Vulcan”, and returned as an admiral Chekov in the crowdfunded 2015 production “Star Trek: Renegades”.
Beyond “Star Trek”, he played the sinister Psi Cop Alfred Bester in 12 episodes of J. Michael Straczynski’s science-fiction series “Babylon 5” between 1994 and 1998, and voiced himself in a 2002 episode of “Futurama”.
Born Walter Marvin Koenig in Chicago to a family of Russian Jewish heritage, he studied psychology at UCLA before training at the Neighborhood Playhouse in New York, where his classmates included Christopher Lloyd, James Caan and Dabney Coleman. He made his screen debut in “Combat!” in 1962 and went on to guest roles in “The Untouchables”, “The Alfred Hitchcock Hour”, “I Spy” and “Columbo”.
Koenig also built a long career as a writer, stage director and acting teacher. He wrote the memoirs “Chekov’s Enterprise” (1980) and “Warped Factors — A Neurotic’s Guide to the Universe” (1998), created the comic book “Raver”, and taught acting at UCLA.
He is survived by his daughter, actress-writer Danielle Koenig. His son, actor Andrew Koenig, died in 2010.
