NCIS, the long-running CBS procedural drama, continues to captivate audiences with its compelling mix of crime-solving, character-driven storytelling, and military intrigue. With Season 22 concluding on May 5, 2025, fans are eagerly anticipating NCIS Season 23. Here’s everything we know so far about the release date, cast, plot details, and more.
NCIS Season 23 Release Date Speculation
CBS confirmed the renewal of NCIS for Season 23 in February 2025, alongside other franchise shows like NCIS: Origins and NCIS: Sydney. While an exact premiere date has not been announced, the series has historically been a fall staple. Based on previous seasons, such as Season 22’s premiere on October 14, 2024, and industry reports, NCIS Season 23 is expected to debut in late September or early October 2025. Some reports speculate a potential premiere as early as August 11, 2025, though this seems optimistic given CBS’s typical scheduling. The show will likely return to its new Tuesday 8/7c slot, following its shift from Mondays in the 2025-2026 lineup, as noted by TV Insider.
NCIS Season 23 Cast: Who’s Returning?
The NCIS Season 23 cast is expected to feature the core team from Season 22, as no major departures were reported following the finale. The main cast members likely to return include:
-
Gary Cole as Supervisory Special Agent Alden Parker
-
Sean Murray as Senior Special Agent Timothy McGee
-
Wilmer Valderrama as Special Agent Nicholas “Nick” Torres
-
Katrina Law as Special Agent Jessica Knight

NCIS Season 23 Plot Details: What to Expect?
As a procedural drama, NCIS Season 23 will likely continue its case-of-the-week format, with each episode introducing standalone mysteries tied to Navy or Marine Corps crimes. However, the Season 22 finale set up a significant overarching narrative that will drive Season 23’s plot, particularly centered on Alden Parker (Gary Cole) and his pursuit of Carla Marino (Rebecca De Mornay).
The Season 22 finale revealed a devastating twist: Carla Marino, Parker’s longtime nemesis, is likely responsible for the murder of his father, Roman Parker (Francis X. McCarthy), as suggested by a lipstick stain on a wine glass. This personal tragedy will push Parker into “very dark places,” according to TV Insider, setting the stage for an emotionally charged arc. The team’s hunt for Marino, connected to a high-stakes plot involving stolen nuclear material and the Nexus cartel, will likely dominate the season’s narrative.
