Walter Koenig, Star Trek's Chekov, dies at 90

Walter Koenig, who played navigator Pavel Chekov in the original Star Trek and seven films, has died at 90, his representatives confirmed Monday.

Walter Koenig, the actor who played navigator Pavel Chekov on the original Star Trek and in seven of its movies, has died at 90. Deadline reported on Monday, Oct. 26, 2026, that his representative confirmed the news. His representatives say he died of natural causes at home in North Hollywood, California.

What we know about his death

According to Deadline, a representative named Zachery McGinnis of Galactic Productions announced the death on Facebook and said Koenig died of natural causes. IGN, citing TMZ, reports that Koenig's daughter, Danielle, and his niece were with him when he died of old age. Rolling Stone, which credits Variety for the first report, says his reps confirmed the same details in a statement.

The outlets differ slightly on timing. TMZ, as relayed by IGN, says he died Sunday. George Takei, who played Sulu, wrote on social media that Koenig passed away early Monday. We are treating the exact day as unsettled and will update if the family clarifies.

The role that defined his career

Koenig was born in Chicago on Sept. 14, 1936, and worked as an actor for roughly a decade before joining Star Trek in 1967, the start of its second season. Chekov was a young Russian officer, written in part to appeal to teenagers, and Rolling Stone notes the part was meant to draw the same young fans as Davy Jones of The Monkees. He stayed through the show's third season, then returned for the films that began with Star Trek: The Motion Picture in 1979 and ended with Generations in 1994.

Outside the Enterprise, he is also remembered for playing Psi Corps officer Alfred Bester on Babylon 5, and he spent years writing for television and meeting fans at conventions.

Who is left from the original cast

Deadline and IGN both note that William Shatner and Takei are now the only surviving main cast members of the original series. Takei said Koenig was best man at his 2008 wedding and that the two stayed friends for nearly 60 years. The loss comes as the franchise marks the 60th anniversary of the first Star Trek episode.

What is not confirmed yet

None of the reports we read include funeral or memorial plans. The two reports we read do not agree on which day he died.

Our take

Chekov was never the captain or the alien, which is partly why people loved him. He was the kid at the console with a huge accent and a shaky claim that everything was invented in Russia, and Koenig played the joke with a straight face for decades. His fans will remember that more than any plot point.
