Night Heat is a Canadian police crime drama series that aired on both CTV in Canada and CBS in the United States. Original episodes were broadcast from 1985 to 1989. Night Heat was the first Canadian original drama series that was simultaneously aired on an American television network during its original broadcast. It was also the first original, first-run drama series to be aired during a late night time slot on a television network in the United States.

During its original run it was the highest-rated Canadian-produced original series in Canada. The show won the Gemini Award for Best Drama Series in both 1986 and 1987.

The show stars Scott Hylands and Jeff Wincott as police detectives Kevin O'Brien and Frank Giambone who work the graveyard shift in an unnamed northeastern North American metropolis. The series follows their nightly police beat as it is chronicled by journalist Tom Kirkwood (Allan Royal) in his newspaper column titled "Night Heat".

Allan Royal plays Tom Kirkwood, a journalist who writes a newspaper column titled "Night Heat" where he chronicles the nightly police beat of detectives Kevin O'Brien, played by Scott Hylands, and Frank Giambone, played by Jeff Wincott. O'Brien is a tough, cynical, veteran police officer and Giambone is his younger, hot-tempered partner. Kirkwood also serves as the show's narrator; his voice-over commentary starts and ends each episode, recapping the lessons learned and acting as a sort of Greek chorus.

The name of the city in which the show takes place is never mentioned. Each episode represents a single night's shift and, as a result, crimes often remain unresolved by the end of the show.

Night Heat was conceived by Sonny Grosso, a former New York City Police Department detective. Grosso served was the show's executive producer along with his partner, Larry Jacobson.

Grosso had over 20 years experience in law enforcement, later working as a narcotics detective. He and his former NYPD partner, Eddie Egan, were the detectives responsible for bringing an end to the infamous drug smuggling ring known as the French Connection. Grosso served as technical adviser on the film based on the investigation. He also worked as a consultant for the film The Godfather and as story editor for the TV series The Rockford Files, Kojak and Baretta.

Grosso and Jacobson were originally approached by CBS to produce a docudrama series following actual police officers, but they considered the potential risk in filming people who had not yet been convicted of a crime and decided against it. Grosso came up with the idea of creating a police series that would feature a realistic look at police work in a documentary style, similar to the 1950s/1960s police drama Naked City. He wanted to depict the life of the everyday police officer, in contrast to the slicker, high-action, high-drama, yuppie-oriented police series of the time such as Miami Vice and Hill Street Blues. The pilot episode was written by Don Flynn, a crime reporter with the New York Daily News.
