Behind on NCIS? Here's where to stream all seasons ahead of the season 21 debut

With just a little less than two months to go until the return of NCIS, you may be wondering just how possible it is to catch up, especially if it’s been a while since you watched the episodes. There are so many great episodes to watch, but where can you stream all 20 seasons before the debut of season 21?

Following NCIS agents as they solve naval crimes, the show has gone through so many changes, especially when it comes to the cast. We’ve grown to love new characters and have had to say goodbye to old ones, especially Mark Harmon’s Leroy Jethro Gibbs. Plus, with the tragic passing of actor David McCallum, it’s only natural to feel inclined to look back at the episodes that featured him heavily.

When we last saw the team, NCIS Agent Nick Torres was confronting a figure from his past, and it looked like he might do something he could later regret. However, anything could happen, and we’re looking forward to finding out how the cliffhanger from season 20 will play out. 

In addition, we also know there will be a tribute episode to David McCallum and his character, Ducky Mallard. Ahead of these episodes, there are plenty of ways to check out past seasons that featured some of our favorite moments with the NCIS crew.

There are a few different streaming services that have NCIS episodes available. Netflix does have the show on its platform, but only up to season 15. Your best bet to watch all 20 seasons is on Paramount+. 

Season 21 will premiere on CBS on Monday, February 12, 2024 so there is plenty of time to catch up, especially if you decide to watch just some of your favorite episodes. It might seem like a lot of episodes to catch up on in less than two months, but looking back at your favorite character moments is worth it!
