Screen One is a British television anthology drama series, produced by the BBC and distributed by BBC Worldwide, that was transmitted on BBC One from 1989 to 1998. A total of six series were broadcast, incorporating sixty individual films, several of which were broadcast as stand-alone specials. The series was born following the demise of the BBC's Play for Today, which ran from 1970 to 1984. Producer Kenith Trodd was asked to formulate a new series of one-off television dramas, the result of which was Screen Two, which began broadcasting on BBC2 in 1985. However, while Play for Today's style had often been a largely studio-based form of theatre on television, Screen Two was shot entirely on film. Three of the episodes ("The Accountant", "News Hounds" and "A Question of Attribution") won the BAFTA TV Award for Best Single Drama.

In 1989, the series was adapted for more mainstream audiences on BBC1, and Screen One was born to follow the lead taken by Channel 4, several of whose many television films had later been released in cinemas.
