On October 14, the 23rd season of NCIS starts in the USA. In Germany, we may have to wait a little longer for the release. If you need something to do until then, we have here the top 5 best seasons so far.
How was this ranking created? NCIS is one of the longest TV series in the United States with 487 episodes across currently 22 seasons. There are now several spin-offs, most recently NCIS: Tony & Ziva. On October 14, 2025, the 23rd season will already start in the USA. If you are looking for something to binge watch until it begins, you can enjoy the top 5 seasons in this list.
For the ranking, we looked at the episode ratings of each episode on IMDb and ranked the seasons based on the average rating. We excluded the spin-offs from the evaluation.
Place 5: Season 3
We start the ranking with one of the earliest seasons of NCIS: Season 3 with an average rating of 8.05 stars. At the end of Season 2, team member Kate Todd was shot by the Mossad agent Ari Haswari. At the season premiere, fellow Mossad agent Ziva David assists in solving the case.
Later, she joins the team around Leroy Jethro Gibbs (Mark Harmon), Anthony DiNozzo (Micheal Weatherly), and Timothy McGee (Sean Murray) as a new, fourth member – although Gibbs and Tony especially have concerns.
With 8.7 out of 10 stars, episode 2 is the highest-rated of the season. It is the second part of the two-part episode revolving around the hunt for Kate’s killer Ari.
