NBC’s One Chicago Sets Premiere Date For 2027 Crossover Event

The new year will bring a new One Chicago crossover event between NBC ‘s Chicago Med , Chicago P.D. , and Chicago Fire , set to air on January 13 from 8-11 p.m. ET/PT. Across three episodes, an unexpected suspect in the death of a patient at Chicago Med will be the focus of a dramatic investigation that involves characters from all three shows.

This latest crossover marks the third consecutive season that One Chicago teams up for an epic night of camaraderie, always to much fanfare. Most recently, Chicago Med , Chicago Fire and Chicago P.D. participated in a crossover in March, which saw the big return of Tracy Spiridakos and Jesse Lee Soffer, their first since exiting the series.

The trio of shows has recently said goodbye to multiple actors, like Joe Miñoso and Dermot Mulroney on Chicago Fire , as well as LaRoyce Hawkins on Chicago P.D. While it would make for a big surprise to see any of them return, special guest stars for the January 2027 celebration have not been revealed.

Chicago Med , Chicago Fire and Chicago P.D. are produced by Universal Television, a division of Universal Studio Group, and Wolf Entertainment.
