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.

Thames Television, commonly simplified to just Thames, was a franchise holder for a region of the British ITV television network serving London and surrounding areas from 30 July 1968 until the night of 31 December 1992. Thames Television broadcast from 09:25 Monday morning to 17:15 Friday afternoon at which time it would hand over to London Weekend Television (LWT).
