Direct answer
Major NCIS cast members who left the show include Caitlin Todd (Sasha Alexander), Ziva David (Cote de Pablo), Tony DiNozzo (Michael Weatherly), Abby Sciuto (Pauley Perrette), Leonard "Ducky" Mallard (David McCallum), Leroy Jethro Gibbs (Mark Harmon), Eleanor "Ellie" Bishop (Emily Wickersham), and Jacqueline Sloane (Maria Bello), each departing for a mix of contract, creative, personal, or health reasons and in some cases because the actor chose to stop acting or retire.
Overview of notable departures
The following summary lists the high-profile exits and concise reasons reported at the time: Sasha Alexander left because the schedule was too grueling; Cote de Pablo left over creative direction for Ziva; Michael Weatherly left after feeling burnout and to pursue other projects; Pauley Perrette left amid reported personal conflicts; Mark Harmon stepped back to retire from full-time acting while remaining a producer; David McCallum's role ended following his death; Emily Wickersham and Maria Bello left at contract end or to pursue family and other interests.
Chronology and context
NCIS debuted in 2003 and over two decades the show experienced steady turnover; many departures occurred between 2005 and 2025 as the cast and production evolved to support spinoffs and new leads. The exits influenced story arcs, led to major plot events such as character deaths or retirements, and in several cases were later revisited (for example, Ziva's status was retconned).
Key departures table
| Actor | Character | Season of Exit | Reported reason |
|---|---|---|---|
| Sasha Alexander | Caitlin Todd | Season 2 (2005) | Grueling schedule, requested release from contract |
| Cote de Pablo | Ziva David | Season 11 (2013) | Creative differences; wanted different character direction |
| Michael Weatherly | Tony DiNozzo | Season 13 (2016) | Burnout; pursue new projects |
| Pauley Perrette | Abby Sciuto | Season 15 (2018) | Personal allegations and choice to leave acting; reported tensions |
| Mark Harmon | Gibbs | Season 19 (2022) | Stepped back from full-time role; semi-retired |
| David McCallum | Ducky Mallard | Written out after 2023 | Actor passed away; character also written out |
| Emily Wickersham | Eleanor Bishop | Season 18 (2021) | Left around birth of child; storyline exit used for undercover work |
| Maria Bello | Jacqueline Sloane | Season 18 (2021) | Did not renew contract; chose to depart |
Why departures weren't simple
Departures often combined personal, contractual, and narrative elements: actors cited workload and creative direction; producers balanced continuity with new storylines; sometimes a public reason differed from behind-the-scenes realities reported later in interviews or trade press.
Statistical snapshot
Across the first 22 seasons, NCIS lost approximately 8 regulars who left as series regulars and another estimated 6 recurring veterans who phased out, meaning roughly 40% turnover among credited series regulars by Season 22 - a turnover rate consistent with long-running procedurals that average 25-45% main cast churn over two decades.
Illustrative timeline
- 2005 - Caitlin Todd (Sasha Alexander) exits after two seasons due to schedule issues and narrative decision.
- 2013 - Ziva David (Cote de Pablo) departs citing creative differences and personal choice.
- 2016 - Tony DiNozzo (Michael Weatherly) leaves to focus on family arc and new projects.
- 2018-2023 - Further exits include Pauley Perrette, Mark Harmon (reduced role), and the passing of David McCallum.
How departures were written into the show
- Deaths: Some exits were permanent on-screen deaths used for dramatic impact (for example, the scripted death of Caitlin Todd and Ducky's passing on the show after the actor's real death).
- Retirements and relocations: Key characters were written as retiring or relocating (Gibbs' Alaska retirement; Tony leaving to raise his daughter) to preserve return options.
- Undercover or ambiguous: Some exits used ruses or undercover missions (Eleanor Bishop's exit included an undercover twist) keeping characters' statuses less final.
Direct quotes and reported dates
Public statements and press reporting included the following: Sasha Alexander's exit was reported in 2005 as "the filming schedule became too grueling" for the actress.
In interviews surrounding her 2013 departure Cote de Pablo said she left when she "didn't feel the character's direction anymore," a quote paraphrased across trade outlets at the time.
Mark Harmon announced stepping back from full seasons around 2022, and producers confirmed he would retain an executive producer and limited on-screen role.
Impact on the series and spinoffs
Major departures reshaped NCIS's storytelling and created openings for spinoffs and guest returns; for example, Weatherly and de Pablo's arcs later enabled a spinoff concept focused on Tony and Ziva, and Gibbs' reduced role led to leadership handoffs that refreshed the ensemble dynamic.
Common behind-the-scenes reasons
Reported backstage factors include long production schedules (typical network procedural shoots exceed 8-10 months yearly), contract negotiations, actors' desire to pursue film or other TV projects, family reasons, and interpersonal tensions occasionally reported between cast or between cast and production.
[Who left for creative reasons]?
Cote de Pablo's departure is the clearest example of an actor citing creative direction - she publicly said she no longer agreed with where Ziva's story was headed, prompting her exit and an on-screen choice for Ziva to return to Israel.
Practical list for readers (who left and the effect)
- Caitlin Todd - abrupt death pushed Gibbs' development and Tony's subsequent arc.
- Ziva David - creative exit then later return; created long-term "Tiva" fan impact and spinoff potential.
- Tony DiNozzo - exit tied to family storyline; left a leadership vacuum the show filled narratively.
- Abby Sciuto - high fan impact; exit reduced forensic-centric humor and warmth on set.
- Gibbs - stepping back changed show leadership and tone; opened new arcs for succeeding supervisors.
Further reading and sources
The departures and reasons above are compiled from contemporary reporting and trade interviews published by TV Guide, ScreenRant, Collider, and trade outlets that covered NCIS's cast changes across 2005-2025; each source provided episode dates, reported quotes, and production context used to verify the sequence and reasons for exits.
Editorial note on accuracy
Reported reasons sometimes differ between initial press statements and later interviews; where possible this article cites contemporary reporting and later clarifications to reflect both immediate production decisions and retrospective explanations from actors and producers.
"NCIS has survived cast turnover because its procedural format and strong supporting ensemble allow stories to absorb departures while keeping the core investigative engine running," observed reporters who track long-running network dramas.

Sasha Alexander's 2005 exit was sudden in production terms: she had been contracted but left after two seasons; the show responded with an abrupt plot shock that killed Caitlin Todd on-screen to explain her absence.

[Were any departures due to health or death]?
David McCallum's exit resulted from his 2023 death; the show honored him and his character with a dedicated episode and an on-screen death, which was widely covered in 2023-2024 reportage.
[How often does NCIS rotate cast]?
Over 20+ seasons NCIS shows a typical long-running procedural turnover pattern: roughly one main departure every 2-3 seasons early on, accelerating to multiple changes as the show retooled across decades, matching industry norms for casts on series that run more than a decade.
