NBC's One Chicago franchise is one of the most successful and popular franchises to ever grace the small screen. What started as a show about firefighters quickly evolved into an interconnected franchise that celebrates first responders working in the police and medical fields as well.
As of 2026, there are a total of 39 seasons of the One Chicago shows between Chicago Fire, Chicago Med, Chicago PD, and the short-lived Chicago Justice. Across those 39 seasons, there are nearly 700 episodes of television to enjoy, which makes the One Chicago franchise the perfect selection for those looking to dive into a new long-term binge-watching commitment.
Of course, if you're going to watch the One Chicago shows from the beginning, the question becomes, how do you do so? After all, like Rome, the One Chicago franchise was not built in a day, and the shows each started at different times, meaning there are certain seasons that take place before some of the shows even began.
How to watch Chicago Fire, PD, and Med in order (plus Chicago Justice)
If you want to watch just one show in the One Chicago franchise, it's easy to just start at the beginning and binge your way through the seasons. However, if you want to do a proper watch of the One Chicago shows from start to finish, it's a bit more complicated given that the shows did not begin in the same year and it took years before NBC put them all together on one night.
The best way to watch the One Chicago shows would be to start at the beginning and then, as the franchise expands, rotate between them by episode, watching episode 1 of each show, then episode 2, and so on. If you take this approach, here is the correct method to watch the shows from start to finish:
- Chicago Fire season 1
- Chicago Fire season 2, episodes 1-10. When you reach Chicago Fire season 2, episode 11, begin Chicago PD season 1 and rotate between episodes.
- Chicago Fire season 3 and Chicago PD season 2 (watch simultaneously, rotating between episodes)
- Chicago Fire season 4 and Chicago PD season 3 (watch simultaneously). When you reach episode 6 of both two shows, add Chicago Med season 1 to the rotation.
- Chicago Fire season 5, Chicago PD season 4, and Chicago Med season 2 (watch simultaneously in this order based on when they aired across NBC's schedule)
- Chicago Med season 3, Chicago PD season 5, and Chicago Fire season 6 (watch simultaneously in this order based on when they aired across NBC's schedule). Add Chicago Justice season 1 into the rotation after watching the 11th episode of Chicago Med, Fire, and PD.
At this point in your binge-watch, One Chicago Wednesdays were established with NBC airing all three shows on the same night rather than having them air on separate nights. This will make binging the seasons much easier as the seasons begin and end at the same time, and the episode orders for the three shows are cohesive moving forward.
Once you hit this stage in your binge, you'll want to rotate between the three shows' respective seasons, watching in the order of Chicago Med, Chicago Fire, and Chicago PD, watching the seasons in the following order:
- Chicago Med season 4, Chicago Fire season 7, Chicago PD season 6Â
- Chicago Med season 5, Chicago Fire season 8, Chicago PD season 7
- Chicago Med season 6, Chicago Fire season 9, Chicago PD season 8
- Chicago Med season 7, Chicago Fire season 10, Chicago PD season 9
- Chicago Med season 8, Chicago Fire season 11, Chicago PD season 10
- Chicago Med season 9, Chicago Fire season 12, Chicago PD season 11
- Chicago Med season 10, Chicago Fire season 13, Chicago PD season 12
- Chicago Med season 11, Chicago Fire season 14, Chicago PD season 13

Now, there is also the aspect of how to watch the various One Chicago crossover events that have occurred through the years, which include crossovers between the One Chicago series as well as other Wolf Entertainment franchises.
