You’re staring at the Paramount+ screen or maybe flipping through cable and wondering how much of your life you're about to lose to the BAU. It's a lot. Honestly, keeping track of how many episodes of Criminal Minds exist is harder than it sounds because the show basically died and came back as a slightly different beast.
If you want the quick answer: As of right now, there are 344 episodes.
But that number isn't static. It's growing.
The show spent fifteen years on CBS, racking up a massive library before "ending" in 2020. Then, streaming changed everything. Criminal Minds: Evolution kicked off, which is technically Season 16 and Season 17, adding more chapters to the book. When you’re trying to figure out how many episodes of Criminal Minds you need to get through to be "caught up," you’re looking at a mountain of content that spans nearly two decades. It’s a massive commitment.
Breaking Down the Seasons: The CBS Era
For most of its life, this was a procedural powerhouse. The original run on CBS consists of 324 episodes.
The early days were wild. Season 1 started in 2005 with Mandy Patinkin as Jason Gideon. It had 22 episodes. This was the era of the "UnSub" being a mystery until the final ten minutes. Most seasons followed a similar pattern, usually landing between 22 and 24 episodes. This was the golden age of network TV where they just churned out content like a factory.
Season 4 is often cited by fans—and honestly, by critics too—as the peak. It has 26 episodes, the longest season in the entire franchise. This is the season with the "Reid in peril" arcs and some of the most haunting writing in the series. If you're counting, by the end of Season 10, you've already sat through 233 episodes. That’s roughly 165 hours of profiling.
Then things started to slim down. By the time we hit Season 14 and Season 15, the episode counts dropped significantly. Season 14 had 15 episodes, and the "final" Season 15 had only 10. People thought that was it. The jet was grounded.

The Evolution Era: A Different Kind of Count
Then came the revival. Streaming changed the math.
When Paramount+ picked up the show for Criminal Minds: Evolution, they ditched the 22-episode slog. Season 16 (Evolution Season 1) consists of 10 episodes. Season 17 (Evolution Season 2) also consists of 10 episodes. This brings the total from 324 up to 344.
The vibe is different now. It’s more serialized. Instead of a new killer every week, they track one major threat across the whole season. It makes the episode count feel "shorter" even though the episodes themselves sometimes run a bit longer than the old 42-minute broadcast standard.
What About the Spinoffs?
If you’re a completionist, the question of how many episodes of Criminal Minds exist gets even more annoying.
There were two spinoffs that most people kind of forget about. Criminal Minds: Suspect Behavior lasted only 13 episodes before getting the axe. Then there was Criminal Minds: Beyond Borders, which managed to squeeze out 26 episodes over two seasons.
If you add those 39 spinoff episodes to the main tally of 344, you are looking at 383 total episodes in the "Criminal Minds Universe."
But let’s be real. Most people just care about the main BAU team. Prentiss, Rossi, Reid, Morgan, Garcia—that’s the core. The spinoffs didn't have that magic, which is why they didn't last. They’re basically footnotes in the larger history of the show.

Why the Number Keeps Changing
The reason people keep searching for the episode count is that the show is currently active. Unlike The Wire or Breaking Bad, where the number is set in stone, Criminal Minds is a living thing. Season 18 has been confirmed.
When Season 18 drops, the total will likely jump to 354.
There’s also the matter of "hidden" content. There are various featurettes and behind-the-scenes specials, but they don't count toward the official episodic total. If you’re a purist, you stick to the numbered episodes that aired on TV or streamed on Paramount+.
How to Watch Them Without Losing Your Mind
If you're starting from scratch, don't look at the number 344. It's too big. It's intimidating.
Instead, look at it in blocks.
- The Gideon Years (Seasons 1-2): 45 episodes.
- The Hotch/Prentiss/Morgan Era (Seasons 3-7): 117 episodes. This is the "prime" era.
- The Transition Years (Seasons 8-12): 117 episodes. This is where cast changes started happening frequently.
- The Final CBS Push (Seasons 13-15): 45 episodes.
- The Evolution Era (Seasons 16+): 20+ episodes and counting.
Honestly, the best way to handle the volume is to realize you don't have to watch every single one. There are "monster of the week" episodes in Season 9 that have zero impact on the overall plot. But if you want the full experience, you’re looking at weeks of continuous viewing.
The Impact of the Episode Count on Syndication
Part of why there are so many episodes is because of how TV used to work. To get a "syndication deal"—where a show is sold to local stations to play every day at 4:00 PM—you usually needed 100 episodes. Criminal Minds hit that mark early and just kept going.

This is why you can turn on ION Television or WE tv at almost any hour of the day and see Joe Mantegna's face. The sheer volume of episodes makes it a goldmine for cable networks. They can play a marathon for 24 hours and not repeat an episode.
Is Every Episode Actually Canon?
In a show this long, there are bound to be mistakes. With over 340 episodes, the writers sometimes forget what they wrote ten years ago. Fans have pointed out inconsistencies in character backstories—especially Reid’s family history and Rossi’s past marriages.
But officially? Yes, every single one of those 344 episodes is canon. Even the weird ones. Even the ones where the UnSub is basically a superhero. It all counts toward the history of the BAU.
The sheer longevity of the show is a testament to the formula. People love watching smart people catch bad people. Whether it's episode 10 or episode 310, that core appeal doesn't change.
Finalizing Your Binge Plan
If you're planning to tackle the whole thing, here is how you should actually do it.
First, ignore the spinoffs. They aren't necessary for the main plot and usually just confuse things.
Second, pay attention to the season finales. Criminal Minds is famous for its cliffhangers. The Season 3 finale, "Lo-Fi," is a classic example. It’s one of the few times where the episode count actually matters because the story is so tightly wound between the end of one season and the start of the next.
Third, keep a "cast tracker" handy. People leave and come back constantly. Paget Brewster (Emily Prentiss) has left and returned so many times it's hard to keep track without a spreadsheet. A.J. Cook (JJ) was famously let go and then brought back after a fan revolt.
Next Steps for Your Rewatch:
- Check your streaming platform: Most of the series is on Paramount+, but Hulu and Netflix sometimes have specific seasons depending on your region.
- Start with "Extreme Aggressor": That's Season 1, Episode 1. Don't skip the early stuff; it sets the psychological foundation for everything that follows.
- Note the shift in Season 16: Be prepared for the change in tone. It gets darker, the language gets a bit more "streaming-appropriate" (they can swear now), and the pacing slows down.
- Track the "Golden" episodes: Look up fan-favorite lists to make sure you're paying extra attention during episodes like "100," "Revelations," and "Entropy."
