Time After Time is a 1979 science fiction novel by American writer Karl Alexander. Its plot speculates what might have happened if H. G. Wells had built a real time machine to travel to the 1970s in search of Jack the Ripper.

The novel was adapted to film the same year, under the same title, by Alexander's friend Nicholas Meyer who had optioned the story after reading the early pages. Meyer wrote his screenplay as Alexander finished the novel and the two freely shared ideas for their respective iterations. A short-lived television series adaptation aired in 2017.
