The 2026 TV schedule recently marked the end of NCIS Season 23, but the show definitely isn't done for good. CBS' long-running procedural is coming back for Season 24 this fall and will be joined by three spinoffs next season as well. It’s hard to believe the flagship show is still going strong after all this time, and even Mark Harmon is OK admitting his shock over the once-struggling series still being on the air.
Some may not remember (or even know this), but NCIS is actually a spinoff of the military legal drama JAG, which ran for 10 seasons and ended in 2005. NCIS has gone on to become even more successful than its predecessor, spawning a whole franchise, but the Mothership took a while to really find its footing.
