There have been a lot of changes to the Chicago Fire cast over the years. We’ve seen beloved characters walk away after their character arcs came to a close, as new faces emerged and became integral parts of the cast.

The Chicago Fire cast is filled with amazing actors, some who have been with the series from Day 1 and others whose journeys on the show have only just begun. Regardless of when they made their debuts though, these characters all play a part in making the show what it is today.

With so many casting changes and such a large ensemble, it can be hard to keep track of the Chicago Fire cast. Fortunately, we’re here to help! Below we break down all of the season’s key players via a guide to the Chicago Fire season 11 cast.
