The drama is part of a shared television universe also inhabited by Chicago PD, Chicago Med and Chicago Justice, with crossovers between the four shows expected to continue this year.
As one star returns, another exits: Deadline reports that Alberto Rosende is bowing out of the role of firefighter Blake Gallo under "amicable" circumstances, presumably with an eye to pursuing other projects.
Read on for more details on the upcoming episodes, including the latest news and speculation on when they could arrive on Sky and NOW in the UK.

Chicago Fire season 12 release date

Chicago Fire usually returns in the autumn of each year, following a brief hiatus over the summer as the cast and crew get prepped for their next round of shooting.
However, due to the lengthy strike organised by the Screen Actors Guild (SAG) and the Writers Guild of America (WGA), this process was delayed – hence why Chicago Fire season 12 is making its US premiere on Wednesday 17th January.
The programme returns to the 9pm slot on NBC, while it will also be available on Peacock in the US. However, fans in the UK are still awaiting an exact return date.
The show is expected to continue airing on Sky Witness and NOW, which has typically debuted seasons a few months later than the US broadcasters – which would suggest a spring 2024 launch for Chicago Fire.
However, given that the show is already running behind, it's possible we could see a change in course this year. We'll update this page as new information comes in.
Chicago Fire season 12 cast: Who could return?

Chicago Fire fans can expect to see the following stars return in season 12:
- David Eigenberg as Lieutenant Christopher Herrmann
- Joe Minoso as Joe Cruz
- Miranda Rae Mayo as Lt Stella Kidd
- Kara Killmer's return as Sylvie Brett
- Daniel Kyri as Darren Ritter
- Hanako Greensmith as Violet Mikami
- Taylor Kinney as Kelly Severide
- Rome Flynn as Jake Gibson
Christian Stolte's future with the show is now in question following the events of season 11's dramatic finale.
Randall "Mouch" McHolland appeared to be recovering from his gunshot injury until Herrmann suddenly saw him flatline in hospital as blood soaked through his blanket.
While he could still pull through, this wouldn't be the first time that the writers have killed off a major character on this show.
Taylor Kinney's future as Kelly Severide was previously also in doubt, after the star took a temporary leave of absence. However, it has now been reported he will indeed be back at the start of season 12.
Rome Flynn (How to Get Away with Murder) has also been added to the cast as amateur boxer Jake Gibson, who crosses paths with team at Firehouse 51 and becomes a recurring player throughout the season (via Deadline).
However, Alberto Rosende is officially out as firefighter Blake Gallo, after amicably parting ways with Dick Wolf Productions.
