Let's Go Back is a nostalgia-based game show that tested contestants' knowledge of pop culture from 1950 to 1989. It ran on Nostalgia Television from July 8, 1991 to May 28, 1993, with reruns airing sporadically for a number of years thereafter. Scott Sternberg was the host, creator and executive producer, while Charlie O'Donnell held announcing duties.

The show is remembered for its acapella, Doo-Wop style theme song and music cues, whose performers are unknown to this day.
