49 free Chicago P.D. trivia questions with answers — entertainment quiz, new questions added Oct 2026.
This Chicago P.D. trivia quiz covers Dick Wolf's police procedural from its 2014 premiere through its renewal for a fourteenth season. Expect questions on Sergeant Hank Voight and the Intelligence Unit, the detectives and patrol officers who have passed through the 21st District — Lindsay, Halstead, Upton, Dawson, Olinsky, Ruzek, Burgess, Atwater, Platt and the newer recruits — and the back-stories the show built for them. There are rounds on the One Chicago crossovers with Fire, Med, Justice and Law & Order: SVU, the Old Maxwell Street station house that once stood in for Hill Street Blues, the casting changes before and after the premiere, and the reviews. Early rounds suit casual viewers; later rounds are for fans who know which episode killed Sheldon Jin. Every answer was checked against encyclopaedia entries before publishing.

Q 04Chicago P.D. follows the patrol officers and Intelligence Unit of which fictional police district?

Q 05At which bar, owned by Chicago Fire characters, do Chicago P.D.'s detectives drink?

Q 06Which Chicago Fire lieutenant did Voight clash with after his son's DUI accident?
Matthew Casey

Q 12Which One Tree Hill star played Detective Erin Lindsay on Chicago P.D.?

Q 23How does Alvin Olinsky die at the end of Chicago P.D.'s fifth season?
