David Timothy Scarboro (3 February 1968 – 27 April 1988) was an English actor who was best known for portraying Mark Fowler in the British soap opera EastEnders from the programme's inception in February until April 1985 before appearing intermittently between 1986 and 1987.

Elements of the UK tabloid press reported that Scarboro had been fired from the show for turning up late for filming and being unco-operative on set. Away from the series Scarboro initiated libel proceedings after several national papers published inaccurate stories about his private life, but the press continued to pursue him and his family. The News of the World discovered that Scarboro was in a psychiatric unit, and published photographs of the place. Scarboro subsequently left the unit because he could no longer get adequate treatment, and inaccurate stories about his condition were being published.
