Mark Harmon Breaks His Silence as ‘NCIS’ Fans Go Wild About His Shocking Career News
NCIS star Mark Harmon famously portrayed Leroy Jethro Gibbs for 19 seasons.
Mark left the CBS drama in 2021, and fans have been begging for him to return to the show.
CBS announced Mark will make a guest appearance on NCIS and NCIS: Origins on November 11, 2025, and the actor spoke out about the news.
It’s been four years since we last saw Mark portray Leroy Jethro Gibbs on the CBS drama, with fans continuing to hope for his return every single week. And while he is an executive producer and narrator on the spinoff series NCIS: Origins (Austin Stowell plays a younger Gibbs on that show), it’s just not the same as seeing Mark on TV in real-time! But trust the hit TV franchise to hear fans’ cries for more Mark, because they seriously delivered with an announcement that’ll leave everyone absolutely shook.
Thanks to a report from Deadline October 28, fans learned Mark Harmon will return to NCIS in 2025. In fact, he’s set to make a special guest appearance during the upcoming NCIS and NCIS: Origins crossover event on November 11, 2025 on CBS, which will see the two shows coming together for a storyline fans will see over the course of a two-hour period.
