NCIS, the long-running military police procedural series, has been renewed for a 21st season. The show, which debuted in 2003, is a spinoff of the legal drama JAG. Season 21 is expected to continue exploring naval crimes with the special agents of NCIS. The new season will feature both familiar faces and new characters. Originally scheduled for release in 2023, the season has been delayed due to strikes by performers and writers. The premiere date is now expected to be in early 2024. NCIS Season 21 will air on CBS and can also be streamed on Paramount+.
