Bliss is a British television science thriller series first broadcast on 11 October 1995. It ran for a total of five episodes on ITV. The series starred Simon Shepherd as Dr. Sam Bliss, a medical research scientist based at Cambridge University, and widowed father-of-two, who often finds himself investigating bizarre and unexplained deaths, with the help of his assistant, Dr. Melanie Kilpatrick (Sian Webber). Initially broadcast as a single stand-alone pilot episode in 1995, Bliss spawned a run of four episodes, which followed in 1997.

The initial pilot was directed by Marc Evans and written by novelist Michael Stewart. Jonathan Hyde, Reece Dinsdale and Jennifer Hilary co-starred in the pilot, alongside Sarah Smart and Zoë Hart, who later reprised their roles for the series. The initial pilot drew a viewing audience of approximately 10 million, while viewing figures for the series averaged around 7 million. In 2000, both the pilot episode and series were released on VHS via Carlton Television. Neither the pilot episode, nor the series, have been released on DVD.
