With NCIS returning for its 23rd season, fans are more eager than ever to know who’s coming back, who’s leaving, and who might surprise us with a new appearance. After over two decades, the beloved CBS crime procedural still knows how to keep things fresh, even as it honors the legacy of its original cast. Here’s everything we know so far about the cast lineup for next season.
Returning Favorites
Sean Murray (Timothy McGee) remains the bedrock of the team. As McGee continues to grow into a leadership role, his loyalty and tech-savvy style continue to shape the team’s culture. Expect more emotional depth from him in the upcoming season, especially with hints of personal storylines.
Wilmer Valderrama (Nick Torres) returns despite last season’s intense cliffhangers. His troubled past and his fierce loyalty to his team continue to make him one of the most complex characters on the show.
Katrina Law (Jessica Knight) will also be back. She’s quickly become a fan favorite with her no-nonsense attitude, precision skills, and ability to balance emotion with professionalism.
Diona Reasonover (Kasie Hines) remains the quirky, brilliant heart of the forensic department. Her unique energy and sharp mind will continue to keep the lab running smoothly.
Brian Dietzen (Dr. Jimmy Palmer), the ever-empathetic chief medical examiner, is returning. His steady presence and emotional intelligence remain vital to the team dynamic.
Special Return: Rocky Carroll and Gary Cole
Rocky Carroll (Leon Vance), the long-time NCIS Director, will be back, providing structure and gravitas to the team.
Gary Cole (Alden Parker), who stepped in following Mark Harmon’s departure, continues to find his rhythm as the team leader. While fans were initially unsure, Cole has grown into a more nuanced version of a team boss—more collaborative, less mysterious, but still authoritative.
Who’s Not Returning?
As of now, there are no confirmed major departures, but some recurring characters from previous seasons are not expected to return. Fans continue to hope for guest appearances from past icons like Michael Weatherly (Tony DiNozzo) or Cote de Pablo (Ziva David)—and with NCIS, never say never.
Possible New Faces?
CBS has been tight-lipped about any new cast members, but it’s possible we may meet new recurring agents, analysts, or even family members connected to current team members. Every few seasons, NCIS introduces a fresh face that re-energizes the dynamics, and season 23 may be no exception.
Final Thoughts
As the franchise flagship continues to evolve, NCIS proves it still has stories to tell. While it may never fully return to its Gibbs-era roots, the current cast brings a fresh energy that balances legacy and innovation. Whether you’re a day-one viewer or a recent fan, the next season’s cast is ready to deliver action, mystery, and emotional storytelling in true NCIS fashion.
