Time Machine: The Journey Back is a combination documentary short-sequel to George Pal's 1960 film The Time Machine, hosted by Time Machine star Rod Taylor and produced and directed by Clyde Lucas. The film was produced in 1993 for airing on PBS stations.

The film's first section is about the time machine prop from The Time Machine, not the film itself, and includes interviews with Academy Award-winner special effect creators Wah Chang and Gene Warren. In its second section, Michael J. Fox sits in the time machine prop and talks about his experience with the DeLorean sports car time machine from the 1985 film Back to the Future. In the film's final section (written by The Time Machine screenwriter David Duncan), Rod Taylor, Alan Young, and Whit Bissell reprise their roles from the original 1960 film.
