In February 2022, CBS announced that the network had renewed NCIS for Season 21, which will air during the 2023-2024 TV season.

The network said in a statement at the time, “We are excited to announce that we have renewed NCIS for Season 21. We look forward to seeing you next season.”

While no release date has been announced yet, CBS has confirmed that the series will remain in its Monday night time slot at 9:00 PM ET, with new NCIS: Hawaii with new Season 3 episodes airing at 10:00 PM ET following.
