Yes, Criminal Minds Evolution Season 4 is officially confirmed. Paramount+ announced the renewal on March 5, 2025, two full months before Season 3 even premiered on May 8. Filming kicked off in late May 2025, with the cast back on set and production running through summer. No exact premiere date has been announced, but a 2026 release on Paramount+ is expected, consistent with the franchise’s recent yearly rhythm.
If you have been following this show since its 2022 debut, you already know Paramount+ treats it like clockwork. But Season 4, technically the 19th season of the entire Criminal Minds franchise, is shaping up to be a genuine pivot point for the BAU, not just another lap around the same track. Here is everything casual fan posts are getting wrong or skipping entirely.
Is Criminal Minds Evolution Season 4 Really Happening?
Absolutely. The renewal came before Season 3 had a single episode in the air, which is rare even for Paramount+ flagship titles. Paget Brewster posted on X in March 2025 that she was doing physical therapy specifically to be ready for the May shoot start. The cast photo dropped May 30 on the official Criminal Minds Instagram, with all seven core members visible on set. This is one of the fastest back-to-back production cycles in the Evolution era.
What Is the Season 4 Premiere Date?
No official date has been locked. What we do know is that Season 3 ran from May 8 to July 10, 2025, and production on Season 4 began immediately after. Seasons 2 and 3 premiered just 11 months apart, which is an aggressive turnaround for a scripted Paramount+ drama. If that pace holds, a spring or early summer 2026 window is realistic, but Paramount+ has not committed to any specific part of the year for this franchise.
Who Is in the Cast for Season 4?
The entire core BAU returns: Joe Mantegna as Rossi, Paget Brewster as Prentiss, A.J. Cook as JJ, Kirsten Vangsness as Garcia, Aisha Tyler as Tara Lewis, Adam Rodriguez as Alvez, and RJ Hatanaka as Tyler Green. The notable addition is Jeri Ryan, best known as Seven of Nine in Star Trek: Voyager and Star Trek: Picard, where she won Saturn Awards in both 2001 and 2024. Her role is undisclosed, but she is confirmed for at least the Season 4 premiere. Showrunner Erica Messer noted that Ryan and premiere director Doug Aarniokoski go back years from their shared Star Trek work, which is how the casting came together organically.
What Happened to Josh Stewart and Will LaMontagne?
Will LaMontagne is dead and gone from the show. Josh Stewart had been appearing in a guest capacity since Season 2 of the original CBS run, but his scheduling made returns impossible. Will LaMontagne was killed off in Season 3, Episode 2, which aired May 15, 2025, a blunt and permanent exit that caught even longtime viewers off guard. A.J. Cook confirmed JJ’s grief will be a thread carried through the entirety of Season 4, not resolved in a single episode.
Will Spencer Reid Return in Season 4?
This is the question every forum is debating. Matthew Gray Gubler did reprise Dr. Reid for one episode of Season 3, his first Evolution appearance. However, Gubler now has the CBS drama pilot Einstein lined up for the 2026-2027 network season, which creates a real scheduling conflict. Showrunner Erica Messer told TV Insider that no appearance from Gubler is currently planned for Season 4 due to the writers’ room timing and his availability. No confirmation either way, but the odds are lower than fans hope.
What Is the Season 4 Storyline and New Unsub?
Erica Messer confirmed that Season 4 will feature a new season-long unsub, and crucially, the audience will learn who the unsub is before the BAU does, which mirrors the Voit structure from earlier seasons. She also promised the season would lean into what she called “real, simple, scary stories” that take the audience into the dark and back out. Meanwhile, Elias Voit has transitioned from invisible killer to public figure. Messer described him in Season 4 as a household name, as famous as Ted Bundy, serving life without parole and now forced to deal with unwanted celebrity. His presence in Season 4 will be a very different dynamic than the cat-and-mouse of the previous three seasons.
Who Gets the Spotlight in Season 4?
Showrunner Erica Messer was specific about this: Adam Rodriguez’s Luke Alvez is the breakout focus of Season 4. She told entertainment outlets over the summer that his arc kicks off hard in Episode 2, and that she sees this as Alvez’s season to grow. Additionally, Zach Gilford will make his directorial debut behind the camera on Episode 7, which is a notable creative milestone for someone who spent three seasons playing the franchise’s most psychologically complex villain.
Will Hotch or Morgan Come Back in Season 4?
No confirmation for either. Thomas Gibson, who played Aaron Hotchner, left the original CBS series under difficult circumstances and has not been part of Evolution at any point. Shemar Moore’s return as Derek Morgan has been a fan request since 2022, but Messer has consistently cited scheduling and the writers’ room timing as barriers. Neither is currently planned for Season 4, though the showrunner has never closed the door permanently.
Is Criminal Minds Evolution Season 4 the Last Season?
Nothing suggests cancellation is on the table. Paramount+ renewed Season 4 in March 2025 before Season 3 even aired, which is not the behavior of a platform cooling on a title. The franchise has now reached 19 seasons across its full history, and the Evolution era has shown Paramount+ is willing to invest in a yearly cycle. The show is one of the streamer’s most consistent performers, and the early renewals are a deliberate strategy to keep the cast and crew committed. Season 5 is not confirmed, but Season 4 is clearly not being treated like a final chapter.
The BAU’s Next Chapter Is a Real Unknown, and That’s the Point
What makes Season 4 genuinely interesting to watch develop is that it is the first Evolution season without a direct cliffhanger feeding it. Season 3 wrapped more neatly than expected, with the BAU celebrating a rare clean win. That creative reset gives Erica Messer room to build something new from the ground up rather than service an existing mystery.
The Jeri Ryan casting, the Alvez spotlight, Gilford stepping behind the camera, and a new season-long unsub who the audience knows before the BAU does, all signal that the writers are treating this less like a sequel and more like a second act. If the 2026 premiere lands in the same spring window as Season 3, the BAU will have maintained one of the tighter production rhythms in prestige cable drama. That alone is worth paying attention to.
