The final season of Mayor of Kingstown is now in production. After that dark and deadly Season 4 finale ending changed everything for the heroes of the Paramount+ drama, the Taylor Sheridan-verse crime series was renewed for a fifth season to finish out the series.

Season 4 of Mayor of Kingstown amped up the grit with tons of shocking character demises and clashes, so what does the future hold for Mayor of Kingstown? Here’s a look.

When will Mayor of Kingstown Season 5 premiere?

No premiere date details have been revealed for Mayor of Kingstown Season 5, and the past is definitely not prologue with this show. Previously, the seasons have aired on very scattered premiere timelines, with Season 1 dropping in November 2021, Season 2 in January 2023, Season 3 in June 2024, and Season 4 in October 2025. The series went into production, according to cocreator and star Hugh Dillon, in early March 2026.

Paramount+ confirmed the start of production on March 13, sharing behind-the-scenes photos of the stars on set.

'Mayor of Kingstown' Stars Break Down That Brutal Season 4 Finale

What will happen in Mayor of Kingstown Season 5?

The new season will follow up on the consequential Season 4 finale, which saw Kyle take revenge against Merle Callahan (Richard Brake) for the murder of his wife, Tracy, in an uncharacteristically brutal fashion.

The description for the season tells us, “This season, in the wake of Tracy’s murder and the vengeance visited upon Callahan by Mike and Kyle, FBI agent Russell Hardy arrives in Kingstown searching for the ‘fugitive’ Callahan. A true lawman, Agent Hardy threatens to unearth all of Mike’s sins and secrets and disrupt Kingstown’s tenuous balance of power.”

What will that look like, exactly? The cast did share some clues: “With all the damage that he’s doing, it may feel good in the moment, but I think that he’s going to have a hard time dealing with himself if this story goes on,” Handley told TV Insider of his character’s gutwrenching arc.

Meanwhile, Ian won the lottery on a scratch-off after expressing a desire to leave Kingstown for Montana; Cindy found herself in the middle of a deadly gang war inside the prison’s infirmary; and Bunny successfully usurped Frank Moses to take over his Detroit-based depot empire… for now, at least.
