The Rivals of Sherlock Holmes is a British anthology mystery television series produced by Thames Television which was originally broadcast on the ITV Network. There were two series of 13 fifty-minute episodes; the first aired in 1971, the second in 1973. The programme presented adaptations of short mystery, suspense or crime stories featuring, as the title suggests, detectives who were literary contemporaries of Arthur Conan Doyle's Sherlock Holmes.
The Rivals of Sherlock Holmes took its inspiration – and title – from a series of published anthologies by Hugh Greene, elder brother of author Graham Greene and the former director-general of the BBC. Greene is credited on the programme as a creative consultant.
