My Hero is a British television sitcom, created by Paul Mendelson, and produced for the BBC between 2000 and 2006. The series follows the exploits of an alien superhero known as "Thermoman" - a multi-powered superhero who originates from the planet Ultron - during his time between missions after falling in love with a British nurse he rescued. Although incredibly intelligent amongst his kind, Thermoman is unfamiliar with human life, which not only leads others to consider him dim-witted and idiotic, but also causes problems due to his many misunderstandings.

The main role of Thermoman was portrayed by Ardal O'Hanlon up until 2005, before he was replaced by James Dreyfus for the final series. The cast itself remained largely unchanged throughout its broadcast history, and included Emily Joyce, Lill Roughley, Tim Wylton, Lou Hirsch, Hugh Dennis, Geraldine McNulty, and Philip Whitchurch. Unlike most British sitcoms, Mendelson co-wrote episode scripts with a large team of writers. Each series also featured a varying number of episodes, with the first and second series containing six episodes, series three through five containing 10 episodes each and series six containing 8 episodes, with a Christmas Special for 2000.

Despite its viewing figures going into decline by the time of Dreyfus' appearance, the show remained a regular feature on British television, being regularly repeated on Gold in the United Kingdom. In the United States, the series was shown on PBS and, briefly, BBC America. In Australia, UKTV offered reruns of the first three series, while BBC Entertainment provided repeats for Scandinavia. Three of the six series have been released on DVD; two on Region 1 DVD and one on Region 2. Fans have since petitioned the BBC to release the complete series on DVD.
