Reacher season 4 release date
Reacher season 4 hit Prime Video on August 12, 2026.
Ritchson previously took to Instagram to share the news, writing, "We got a heavy one-two punch coming your way," adding that Reacher spin-off show Neagly will hit Prime one month after Reacher season 4, on September 16. Entertainment Weekly later added that Reacher season 4 will kick off with a three-episode premiere.
Reacher season 4 plot
The series as a whole is based on Lee Child's works, with each season exploring a separate book. Season 1 was adapted from book 1, The Killing Floor, season 2 was taken from book 11, Bad Luck and Trouble, and season 3 is based on book 7, The Persuader. Reacher season 4 adapts Child's 13th Reacher book, Gone Tomorrow.
Per the official Reacher season 4 synopsis: "Jack Reacher is drawn into a deadly mystery on a late-night subway ride after a chance encounter with a distraught stranger goes horribly wrong, pulling him deep into a high-stakes web of government secrets and ruthless political power."
Reacher season 3 recap and ending explained
Reacher season 3 saw the ex-soldier go to his most vulnerable state yet as we went undercover and lived in enemy territory. In order to find a lost DEA informant named Teresa, Reacher posed as a wannabe bodyguard to gain access to a dodgy rug import business involved in shady dealings. However, once inside it became apparent that a dark figure from Reacher’s past who he thought he had killed years ago, Xavier Quinn, was in control of the whole thing.
With Reacher out for revenge and DEA agent Susan Duffy hellbent on finding her informant, the season came to a fiery end with Reacher pointing a gun at the man he hates most. For more on that, check out our Reacher season 3 ending explained guide.
However, as each season of Reacher follows a separate story, we don't think season 4 will continue the New England Storyline. But some characters from season 3 could well show up in the next installment just as seasons 1 and 2 stars, such as Maria Sten's Franic Negaley, have appeared in following seasons.
Reacher season 4 cast
The show shakes up the cast every season due to Reacher landing in a brand new town each time. This time, Jacob Merrick and Tamara Green were Reacher's go-to guys. The villains were terrorist duo Lila and Amisha Hoth, played by Agnez Mo and Angunn, respectively.
Some things to note to note: Jay Baruchel did not end up playing Jacob due to personal matters, and the role instead went to Barry actor Christopher Rodriguez-Marquette (though Baruchel will indeed join Reacher season 5 as a different character). Sydelle Noel, star of Netflix's GLOW, played NYPD Homicide Detective Tamara. In the novel, her character's name is actually Theresa Lee.
The cast list includes:
- Alan Ritchson as Jack Reacher
- Christopher Rodriguez-Marquette as Jacob Merrick
- Sydelle Noel as Tamara Green
- Agnez Mo as Lila Hoth
- Anggun as Amisha Hoth
- Dean Armstrong as Foster
- Kevin Weisman as Russell Plum
- Marc Blucas as John Sampson
- Kathleen Robertson as Elsbeth Sampson
Reacher season 4 trailer
The official trailer dropped in July 2026, one month ahead of release. The clip, which you can watch above, opens with Alan Ritchson's ex-soldier sitting inside a subway car when he witnesses a woman end her own life. The police pick up Reacher for the crime, but soon after escaping their clutches, Reacher sets out to solve the death, which he thinks was suspicious. Reacher meets up with the woman's brother (Christopher Rodriguez-Marquette), who is adamant she didn't kill herself. From then on, the two are pulled into a dangerous web of criminal activity.
Is Reacher season 4 the final season?
Reacher season 5 was officially greenlit in May, with principal photography set to begin in August. Per Deadline, season 5 is based on the Lee Child novel Make Me, which is set in rural Oklahoma. The synopsis is as follows: "After his train stops in the mysterious town of Mother’s Rest, Reacher teams up with a private investigator in the search for a missing person and uncovers a dangerous and deadly criminal conspiracy."
Ritchson is also star is set to make an appearance in spin-off Neagly. Prime Video shared the first look at the upcoming spin-off on Twitter, which shows Reacher accompanying Neagly to a funeral.
