Criminal Minds Season 18: Cast, Release Date, and Reid Return

There’s a specific kind of anticipation that builds when a long-running crime drama adds another chapter. For devotees of Criminal Minds, season 18 — the third under the Evolution banner — landed on May 8, 2025, with a surprise one-episode return of Spencer Reid. Here’s what we know about the cast, release schedule, and what might come next for the BAU.

Announced: June 5, 2024 · Filming began: August 2024 · Season designation: Season 18 / Evolution Season 3 · Platform: Paramount+

Six key facts, one pattern: season 18 is both a continuation and a pivot for the franchise.

Is there a season 19 for Criminal Minds?

Paramount+ has not officially announced a season 19. The current renewal — announced June 5, 2024 — covers season 18, the third season of the Evolution revival. Criminal Minds: Evolution was initially conceived as a limited series, but strong viewership drove two additional seasons. The implication: Paramount+ is waiting to see viewership data before committing further.

What is the status of Criminal Minds season 19?

• No official announcement for season 19 has been made (Emily Craig Writer).
• The showrunners have not commented on future seasons beyond 18.
• The pattern of Evolution was originally limited, so season 19 remains uncertain.

Bottom line: Paramount+ has not ordered season 19. Fans hoping for more BAU should brace for the possibility that season 18 might be the final chapter, though the franchise has defied cancellation before.

Is Spencer Reid coming back in season 18?

Matthew Gray Gubler does return as Dr. Spencer Reid in one episode. Appearing in Episode 3, titled “Time to Say Goodbye,” Reid makes a cameo that serves as a farewell for the character within the Evolution universe (Wikipedia). The catch: this closure comes at the cost of Reid’s long-term presence in the franchise.

Why is Reid not in season 18 of Criminal Minds?

• Gubler was unavailable for the entirety of Evolution seasons 16 and 17 due to scheduling conflicts (Emily Craig Writer).
• He was reportedly cast in a CBS pilot titled “Einstein” announced in October 2024 (Emily Craig Writer).
• The single-episode return suggests the character’s story arc is now closed.
