Fans of NCIS are getting an exciting glimpse of Mark Harmon back as Leroy Jethro Gibbs.

Although Harmon left the CBS series in 2021, he has remained connected to the franchise by narrating NCIS: Origins. Now, he’s set to appear on screen again as Gibbs in a crossover event that aired on November 11, 2025.

Ahead of the episode, NCIS shared a teaser showing Gibbs at home, writing notes from an old case-hinting at his possible involvement with both past and present storylines.

The preview quickly sparked emotional reactions from fans, many expressing excitement and welcoming Gibbs back after his long absence.

While it’s unclear whether this marks a longer return to the franchise, Harmon has said he’s open to possibilities, as long as it serves the story. He emphasized the importance of allowing the writers to shape the show’s direction in a way that feels right.

For now, fans are simply thrilled to see Gibbs back on screen, even if only for a special appearance.
