NCIS first premiered in 2003, and this juggernaut of a franchise is showing no signs of slowing down even now - 20 years later.


With three spin-offs and a fourth on the way - NCIS: Sydney - this flagship series for CBS is more popular than ever, which means all eyes are now on what's next in NCIS season 21.

Join us here at as we reveal everything you need to know about whether NCIS will return for season 21, which airs on CBS in the US and Disney Plus in the UK.

Will there be a NCIS season 21?

Yes, NCIS will definitely return for season 21 - and probably for a hundred more years after that, too...

As the third-longest-running scripted, non-animated primetime TV show the US has to offer, NCIS isn't going anywhere any time soon.

In fact, it might even rise up the ranks of longest-running scripted shows ever, where it currently holds seventh place.

We will keep this page updated with all the latest news on NCIS season 21 when we hear more.

NCIS season 21 release date: When will it air?

NCIS usually starts each new season in the autumn like clockwork, but due to the strike organised by SAG-AFTRA and the Writers Guild of America, season 21 will take longer to arrive than expected.

As it stands, new episodes probably won't arrive now until the start of 2024 at the very earliest, and that's only if the unions are satisfied soon.

NCIS season 21 cast: Who could return?

Assuming that everything goes according to plan, here are all the main stars expected to return in NCIS season 21:

  • Gary Cole plays Alden Parker
  • Sean Murray plays Timothy McGee
  • Wilmer Valderrama plays Nick Torres
  • Katrina Law plays Jess Knight
  • Brian Dietzen plays Dr Jimmy Palmer
  • Diona Reasonover plays Kasie Hines
  • David McCallum plays Dr Donald Mallard
  • Rocky Carroll plays Leon Vance

New faces will, of course, join in guest roles, too. And who knows? Maybe some of them could become principal players one day, starting out like some of these stars did.

And if we're very lucky, fan favourites like Mark Harmon and Pauley Perrette might return for guest spots, as well. That would certainly bring more interest to the new season, although the show continues to fare well without them, despite how beloved they are by the fandom.

Is there a trailer for NCIS season 21?

No new footage of NCIS season 21 has been released just yet, and we probably won't see any for some time with the strikes still underway.

Once things are resolved, we will hopefully see a season 21 trailer pop up online by the end of 2023 at the very latest.

NCIS is available to watch on Disney Plus in the UK. You can sign up to Disney Plus for £7.99 a month or £79.90 a year now.
