I, Detective is an American documentary-style series that aired on Court TV (now truTV) from 2001 to 2006.

For a time in early 2014, the show returned in reruns on sister network HLN. At first, it was retitled Detective Files, but a month later, the show returned to its original title. The reruns have been repackaged to include updates at the end of some episodes on what became of the suspect(s) or parties involved since the final verdicts. As of late January 2015, the reruns now air on Justice Network.
