Hammer House of Mystery and Suspense, aired in the United States as Fox Mystery Theater, is a British mystery anthology television series produced in Britain in 1984 by Hammer Film Productions. Though similar in format to the 1980 series Hammer House of Horror, the Mystery and Suspense series had feature-length episodes, usually running around 70 minutes without commercials.

The series was a co-production by Hammer Film Productions with 20th Century Fox Television (as was the 1968 anthology series Journey to the Unknown). It was first aired in the UK by ITV in 1984, though it was shown in different timeslots (and a different running order) throughout the various ITV regions. The Hammer House of Mystery and Suspense series was the last production undertaken by the Hammer film company.
