Mark Harmon Returns to All Season 3 Episodes of NCIS: Origins as Elder Gibbs

Summary
Mark Harmon will appear on screen in every episode of "NCIS: Origins" Season 3, expanding beyond his narration and executive producer role on the CBS prequel.
The season-long return ties to a present-day mystery linked to Gibbs' time at Camp Pendleton in the 1990s, alongside Austin Stowell's younger version of the character.
Harmon last played Gibbs full-time for more than 18 seasons on "NCIS" and exited in Season 19, when the character chose to remain in remote Alaska.
His elder Gibbs has appeared only sparingly in "Origins" so far — in the series premiere and a November 2025 crossover — making Season 3 a much larger on-screen role.
"NCIS: Origins" returns this fall on Tuesdays at 10/9c on CBS and Paramount+ after a Season 2 finale that ended with Gibbs and Lala kissing and Randy being kidnapped.
