New 'One Chicago' Crossover Gets a 2027 Release Date

The next crossover event for the One Chicago franchise has a date set. Characters from Chicago Med, Chicago PD, and Chicago Fire will meet again in the event episode airing in the United States on January 13th.

In this crossover event, spanning three episodes, an unexpected suspect in the death of a patient at Chicago Med will be the focus of a dramatic investigation involving characters from all three series.

This crossover marks the third consecutive season in which the One Chicago franchise unites in a narrative, always surrounded by great anticipation. Most recently, Chicago Med, Chicago Fire, and Chicago PD participated in a crossover in March, which featured the long-awaited return of Tracy Spiridakos and Jesse Lee Soffer—their first appearance since leaving the series.

The trio of productions recently said goodbye to several actors, such as Joe Miñoso and Dermot Mulroney from Chicago Fire, and LaRoyce Hawkins from Chicago PD.

Although the return of any of them would be a big surprise, the names of the special guests for the January 2027 celebration have not yet been revealed.

The One Chicago franchise continues to be a mainstay of NBC's programming, performing strongly on both television and streaming, and maintaining a consistent presence in Peacocks top 10 throughout the season.
