Walter Koenig, who became a sci-fi icon by playing Chekov—the Russian navigation officer aboard the USS Enterprise—in the original Star Trek series as well as its feature films, has died. He was 90 years old.
Koenig’s passing was confirmed by Variety and other outlets, with the trade noting the character of Chekov, who debuted in season two, “was introduced to the series to appeal to teenage viewers—his hairstyle recalled that of the Monkees’ Davy Jones.” As time went on, the character became a more serious member of the Enterprise crew, playing a key role in 1982’s Star Trek II: The Wrath of Khan.
In Star Trek: Picard, the actor gave voice to “President Anton Chekov” for the 2023 series finale. The character was meant to be the son of Pavel Chekov, Koenig’s original character, while also paying tribute to the late Anton Yelchin, who played a younger version of the character in the Star Trek reboot movies.
Koenig also voiced Chekov across multiple Trek video games. Beyond the sci-fi franchise he was best known for, he also appeared in the 1990s series Babylon 5.
Original Trek co-star George Takei paid tribute to his colleague and friend on Bluesky, writing:
“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. When Brad and I married in 2008, Walter stood beside us as our best man.
Just last month, on Sept. 14, he turned 90, on the same day Brad and I celebrated our 18th wedding anniversary. I will always treasure that he and I shared that date.
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.
Rest well, my dear friend. Keep navigating a steady course.
– George.”
