Chicago P.D. is coming back to NBC later this year on the 2026 TV schedule along with the other One Chicago shows, meaning there will be a lot to look forward to... even with a major cast member exiting. Following the One Chicago crossover earlier this year, it’s possible we’ll be able to look forward to more crossovers next season, whether big or small. But I actually just found out a connection that Chicago P.D. has with another NBC series, Hill Street Blues.
Of course, Chicago P.D. is connected to the One Chicago Universe, also consisting of Chicago Fire, Chicago Med, and the short-lived Chicago Justice. It is also connected to fellow Dick Wolf NBC franchise Law & Order through some crossovers with SVU. But that’s not all. TVLine pointed out that there’s yet another connection to a much older NBC series that many people may not have noticed.
