Walter Koenig, who played Pavel Chekov in the original Star Trek series and its films, has died at 90.
His representatives told Variety that he died Sunday, October 25, at his home in North Hollywood, California.
George Takei, who played Hikaru Sulu alongside him, shared a tribute on Monday. “My heart is heavy,” he wrote.

Galactic Productions founder Zachery McGinnis announced the death on October 26. The agency said Koenig died of old age, with his daughter and niece beside him.
Its statement highlighted his years of convention appearances, where he shared his humor and appreciation with fans. His representatives remembered an actor who understood how much Star Trek meant to the people who came to meet him.
Koenig married actress Judy Levitt in 1965, and they remained together until her death in 2022. Their son, actor Andrew Koenig, died in 2010. He is survived by their daughter, Danielle, a writer and comedian.

Takei posted a photograph of the two actors together, recalling how they met on the Enterprise’s bridge in the 1960s. Their characters occupied neighboring stations, with Sulu at the helm and Chekov navigating, and their friendship lasted nearly six decades.
Koenig served as best man when Takei married Brad Altman on September 14, 2008. The date was also Koenig’s birthday. This year, he turned 90 as the couple celebrated their 18th anniversary.
“He was a writer, a teacher, a thoughtful man, and a loyal friend,” Takei wrote, according to Entertainment Weekly. He closed with a farewell to his former navigator: “Rest well, my dear friend. Keep navigating a steady course.”
Chekov Took Koenig From Television to Seven Feature Films
Koenig joined Star Trek in 1967, during its second season. His first broadcast appearance was in “Amok Time,” and he went on to appear in 36 episodes, according to Paramount+.
The Russian navigator became part of the Enterprise’s multinational crew during the Cold War. His enthusiasm and insistence that great inventions originated in Russia supplied some of the show’s humor.
Koenig reunited with the original cast for six theatrical films, beginning with Star Trek: The Motion Picture in 1979. He then appeared in Star Trek: Generations in 1994, bringing his total to seven.
He also contributed behind the scenes, writing “The Infinite Vulcan” for Star Trek: The Animated Series. Decades later, he voiced Federation President Anton Chekov, Pavel’s son, in the 2023 finale of Star Trek: Picard.
In a 1984 Good Morning America interview revisited by ABC News, Koenig credited the franchise with sustaining his acting career and allowing him to pursue writing, directing and producing.
His Later Work Included ‘Babylon 5’ and an Acting Award at 90
Koenig found another science-fiction audience as Alfred Bester, the sinister telepath he played in 12 episodes of Babylon 5. Away from television, he taught acting, worked in theater and wrote books, including the memoir Warped Factors.
Among his later roles was the lead in Frank Crim’s short film Mr. Fleischmann. He played a Holocaust survivor whose new neighbor is the Nazi officer responsible for his parents’ deaths.
The Independent Shorts Awards named Koenig Best Actor at its September 19 annual ceremony at Regal LA LIVE in Los Angeles. The film also won Best Thriller Short.
