Chicago Fire season 15 is set to premiere on NBC on October 7, 2026, at 9 p.m. ET, bringing Firehouse 51 back for another chapter after a high-stakes Season 14 finale and several major cast changes.
The upcoming season will continue the long-running NBC firefighter drama with Taylor Kinney, Miranda Rae Mayo and other established stars returning. At the same time, the show is preparing for the departure of original cast member Joe Miñoso and the exit of Dermot Mulroney.
The new season also introduces Da’Vinchi as Marcus Burke, a firefighter candidate joining Firehouse 51. Behind the scenes, Victor Teran is taking over as showrunner after Andrea Newman completed her run with the series.
These changes make the upcoming season an important transition point for the NBC drama while keeping its central Firehouse 51 setting intact.
When Does Season 15 Premiere?
NBC has scheduled the new season for Wednesday, October 7, 2026.
The premiere will air at 9 p.m. ET on NBC. The series will remain part of the Wednesday-night One Chicago lineup, with Chicago Med scheduled at 8 p.m. and Chicago P.D. following at 10 p.m.
U.S. viewers will also be able to stream new episodes through Peacock after their NBC broadcasts.
The October return gives the drama a clear starting point after the Season 14 finale left several characters facing a dangerous emergency.
NBC renewed the series for a 15th season in March 2026. The renewal ensured that the story of Firehouse 51 would continue into the 2026-27 television season.
Season 14 Finale Leaves Firehouse 51 in Danger
The Season 14 finale created a major cliffhanger for the firefighters of Firehouse 51.
Kelly Severide, Joe Cruz, Mouch and other members of the team became involved in a dangerous building fire. The episode ended with the emergency still unfolding, leaving viewers waiting for answers about what happened inside the burning structure.
The situation sets up an immediate storyline for the new season.
However, not every character’s future was left equally uncertain. Taylor Kinney and Miranda Rae Mayo have confirmed returns for the new season, meaning Severide and Stella Kidd will continue their stories.
The opening episodes will have to deal with the consequences of the Season 14 emergency before the series can move fully into its new character arcs.
NBC has not released every detail surrounding the premiere’s storyline. As a result, specific outcomes beyond the confirmed cast information remain unrevealed.
Taylor Kinney Returns as Kelly Severide
Taylor Kinney will continue playing Kelly Severide.
Severide has been one of the show’s central characters since the beginning. His position with Squad 3 has placed him at the center of major rescue operations, investigations and emergencies throughout the series.
His return is particularly important after the Season 14 finale.
Severide’s professional relationship with Stella Kidd also remains one of the show’s established character connections. Both characters will return for the new season.
Kinney’s continued involvement provides an important link between the long-running Firehouse 51 story and the changes coming in Season 15.
Miranda Rae Mayo Continues as Stella Kidd
Miranda Rae Mayo will return as Stella Kidd.
Stella has become one of Firehouse 51’s most important firefighters and leaders. Her career has developed substantially since she first joined the series, and her relationship with Severide remains a major part of her storyline.
Her return also helps preserve the established leadership structure at the firehouse while other characters depart.
With Season 15 bringing new personnel into Firehouse 51, Stella will be part of an ensemble balancing longtime firefighters with newer members.
Joe Miñoso Leaves After a Long Run
One of the biggest changes coming to the new season involves Joe Miñoso.
Miñoso has played firefighter Joe Cruz since the series premiered in 2012. Cruz became one of Firehouse 51’s most recognizable members and remained part of the show for more than a decade.
Miñoso will leave the series during Season 15.
He is expected to appear in select early episodes before his storyline concludes. That allows the show to give Cruz a proper exit rather than removing the character without explanation.
Cruz’s departure is significant because he has been part of the series from the beginning. His friendships, family storylines and work inside Squad 3 have all contributed to the identity of Firehouse 51.
His exit will therefore create a noticeable change for the remaining firefighters.
The timing also gives the new season another major storyline to handle alongside the aftermath of the Season 14 finale.
Dermot Mulroney Is Leaving as Dom Pascal
Dermot Mulroney is also set to depart during Season 15.
Mulroney joined Chicago Fire in Season 13 as Battalion Chief Dom Pascal. His character arrived after the departure of Wallace Boden, who had served as Firehouse 51’s longtime battalion chief.
Pascal became an important authority figure during his time with the department.
His storyline changed during Season 14, when the character spent an extended period away from the firehouse. Mulroney later returned before the season concluded.
The actor will appear in several early Season 15 episodes before leaving the series.
His exit creates another leadership change for Firehouse 51 as the show moves into its 15th season.
Da’Vinchi Joins the Cast as Marcus Burke
Season 15 will introduce Da’Vinchi as Marcus Burke.
The actor, known for his work in BMF, is joining the NBC drama as a series regular. Marcus is a firefighter candidate assigned to Firehouse 51.
The character brings a different personality to the team. Marcus is described as funny, confident and somewhat defiant, with a sense of humor that can create tension as he adjusts to life inside the firehouse.
His arrival gives the show a new character who can interact with the established firefighters while learning the demands of the job.
Marcus also represents the next generation of firefighters at Firehouse 51.
His presence becomes even more significant as Joe Cruz prepares to leave the series.
The new character is not simply replacing Cruz. Instead, Marcus joins a larger group of firefighters and paramedics who will shape the next stage of the drama.
Victor Teran Becomes Showrunner
There is also a major change behind the camera.
Andrea Newman has left her position as showrunner after 14 seasons with the series. Victor Teran is taking over the role for Season 15.
Teran already has extensive experience with Chicago Fire. He joined the writing staff during Season 10 and later moved into an executive producer position.
His promotion provides continuity because he already knows the show’s characters, production and storytelling style.
At the same time, the change marks a new creative chapter.
Newman had been closely associated with the series for many years. Her departure comes as the show also introduces a new regular cast member and prepares to lose two established performers.
The transition is therefore one of the most notable behind-the-scenes developments heading into the new season.
Who Is Returning?
Several important members of the Firehouse 51 team are continuing with the series.
The confirmed returning cast includes:
- Taylor Kinney as Kelly Severide
- Miranda Rae Mayo as Stella Kidd
- David Eigenberg as Christopher Herrmann
- Christian Stolte as Mouch McHolland
- Hanako Greensmith as Violet Mikami
- Jocelyn Hudon as Lyla Novak
- Brandon Larracuente as Sal Vasquez
Their continued presence gives the series a strong connection to its established cast.
Herrmann and Mouch, in particular, remain among the show’s longtime Firehouse 51 veterans. Violet and Novak continue to represent Ambulance 61, while Severide and Stella remain central to the firehouse’s leadership and emergency response stories.
The returning characters will now have to adjust to the arrival of Marcus Burke and the departures of Cruz and Pascal.
What Happens to Firehouse 51 After the Cast Changes?
The biggest challenge for the new season will be maintaining the familiar Firehouse 51 dynamic while introducing new personnel.
Joe Cruz has been part of the show’s foundation since the first season. His departure changes the balance among the firefighters, particularly those who have worked beside him for years.
Pascal’s exit creates another change at the command level.
Marcus Burke, meanwhile, gives the firehouse a new firefighter candidate who still has to prove himself.
These developments create a different workplace environment without changing the basic focus of the series.
Chicago Fire continues to center on firefighters and paramedics responding to emergencies across Chicago. Personal relationships and professional challenges remain closely connected to the emergency calls.
Season 15 Remains Part of One Chicago
The new season will continue as part of NBC’s One Chicago franchise.
Chicago Fire will air between Chicago Med and Chicago P.D. on Wednesday nights.
The lineup is scheduled as follows:
| Series | Time |
|---|---|
| Chicago Med | 8 p.m. ET |
| Chicago Fire | 9 p.m. ET |
| Chicago P.D. | 10 p.m. ET |
The three shows share a fictional universe and have previously connected through crossover events.
NBC has not announced every future crossover storyline for the new television season. Any specific crossover claims beyond officially announced information should therefore be treated cautiously.
For now, the confirmed schedule keeps all three One Chicago dramas together on Wednesday nights.
Where to Watch the New Season
U.S. viewers can watch Season 15 on NBC beginning October 7.
Episodes will also be available on Peacock following their NBC television broadcasts.
The 9 p.m. ET time slot gives the series a familiar place in NBC’s Wednesday lineup.
Viewers who want to follow the new season from its first episode will need to watch the premiere to learn how the Season 14 cliffhanger is resolved.
The premiere also begins the transition involving Cruz, Pascal and Marcus.
Why the New Season Matters
The upcoming season arrives at a significant point in the show’s history.
Chicago Fire has reached its 15th season while retaining several performers who have been associated with Firehouse 51 for many years. Yet the series is also losing one of its original cast members.
Joe Miñoso’s departure closes a major chapter for the show. Dermot Mulroney’s exit creates another shift in the leadership structure. Da’Vinchi’s arrival adds a new personality to the ensemble.
The showrunner change adds another layer to the transition.
Victor Teran now has responsibility for guiding the series into its next season. His previous experience on the drama gives him familiarity with the show’s established characters and production.
At the center of everything is Firehouse 51.
Severide, Stella, Herrmann, Mouch, Violet, Novak and the other returning characters will continue dealing with emergencies while adapting to a changing team.
Latest Status for the Upcoming Season
The confirmed premiere date is October 7, 2026, at 9 p.m. ET on NBC.
Taylor Kinney and Miranda Rae Mayo are returning, along with several other established cast members. Joe Miñoso will leave the show during the season after appearing in select early episodes.
Dermot Mulroney will also depart after several early Season 15 appearances.
Da’Vinchi is joining as Marcus Burke, a new firefighter candidate at Firehouse 51. Victor Teran is taking over as showrunner following Andrea Newman’s departure.
The season will begin by addressing the major situation created during the Season 14 finale before moving into its new cast and character stories.
For fans, the combination of familiar faces and new arrivals gives the next chapter of the NBC drama a distinctly different lineup while preserving the Firehouse 51 setting that has defined the series for years.
