CBS announced today that NCIS has been renewed for Season 21. The news comes as the network's flagship series is set to hit the 450-episode mark next week.

On the air since 2003, the show is one of CBS' most successful series of all-time, ranking as the longest-running drama currently on the network. It has two spin-offs on the air, 'NCIS: Los Angeles,' which will be ending this spring, and 'NCIS: Hawai'i,' which was also renewed today. An upcoming international spin-off, 'NCIS: Sydney,' is coming this year to Paramount+.

Originating from a concept and characters that were initially introduced in a two-part episode of the CBS series 'JAG,' NCIS was originally referred to as 'Navy NCIS' in its first season. The series follows the Naval Criminal Investigative Service, which is the primary law enforcement and counter-intelligence arm of the United States Department of the Navy. Together, the team works in high-stress situations while dealing with often-complex and always-amusing personal dynamics.

Look for Season 21 of NCIS as part of the 2023-2024 television season this fall.
