Cold Case Files is a reality legal show/documentary on the cable channel A&E Network and the rebooted series on Netflix. It is hosted by Bill Kurtis and the original series produced by Tom Golden. The show documents the investigation of many long-unsolved murders (referred to as "cold cases" in detectives' parlance) through the use of modern forensic science (especially recent advances in DNA techniques), and criminal psychology, in addition to recent breakthroughs in the case(s) involving previously silent witnesses.

On January 19, 2017, Blumhouse Television, AMPLE Entertainment and A&E revived the series for a ten-episode run. The well received reboot features highly cinematic recreations and music. The new episodes first began airing on February 27, 2017. Actor Danny Glover took over for Kurtis as narrator for this new 10-episode series. Kurtis later returned. On August 20, 2021, after a four-year hiatus, the series returned with a new season on A&E, again with Kurtis as the host.
