Chicago P.D. season 1

The first season of Chicago P.D. aired on NBC from January 8, 2014, at 10:00 p.m. EST, to May 21, 2014. The season consisted of 15 episodes.

Production
On March 27, 2013, it was reported that NBC was considering plans for a spin-off of Chicago Fire. Deadline revealed that the proposed spin-off would involve the Chicago Police Department, and would be created and executive produced by Dick Wolf, Derek Haas, Michael Brandt, and Matt Olmstead.

On May 10, 2013, NBC picked up the proposed spin-off, now titled Chicago P.D., for the 2013–14 United States network television schedule. On October 18, the series was given a premiere date of January 8, 2014.

On January 31, 2014, NBC ordered two additional episodes of Chicago P.D., bringing the total number of episodes for the first season to fifteen.

Casting
Tania Raymonde was cast in the planned series as an Officer named Nicole. Kelly Blatz, the lead-actor of Disney XD's Aaron Stone, was also cast as a young but seasoned Officer Elam. Scott Eastwood was set to portray Officer Jim Barnes. Eastwood also co-starred with Tania Raymonde in Texas Chainsaw 3D. Melissa Sagemiller would portray Detective Willhite, a member of the Chicago P.D. Intelligence Unit. LaRoyce Hawkins, in the role of Officer Kevin Atwater, was the only Chicago-area actor originally cast in May. These characters were introduced in the penultimate episodes of Chicago Fire's first season.

Sagemiller's character was dropped after her initial guest spot on Chicago Fire and in the first episode of Chicago P.D.. Jesse Lee Soffer, who already had a recurring role on Chicago Fire as undercover cop Detective Jay Halstead, was added to the main cast in her place. Jason Beghe was cast as Sergeant of the Intelligence Unit Hank Voight and Jon Seda would play the role of Intelligence Unit Detective Antonio Dawson. Patrick Flueger and One Tree Hill star Sophia Bush joined the cast as Officer Adam Ruzek and Detective Erin Lindsay respectively. Marina Squerciati joined the cast in the role of Officer Kim Burgess. Elias Koteas became a member of the main cast and would play Intelligence Unit Detective Alvin Olinsky. Archie Kao was later announced to be playing Sheldon Jin, a tech-expert working with the Intelligence Unit. Stella Maeve was cast in the recurring role of playing Nadia, a pretty 18-year-old escort who is addicted to heroin and goes through a very difficult withdrawal. Both Eastwood and Raymonde, like Sagemiller, departed the series and would no longer be a part of the show's main cast. Sydney Tamiia Poitier was to guest star in five episodes as a Detective, who would eventually crossover on to the parent series, Chicago Fire.
