The Protectors is a British television series, an action thriller created by Gerry Anderson. It was Anderson's second TV series to exclusively use live actors as opposed to marionettes (following UFO), and his second to be firmly set in contemporary times (following The Secret Service). It was also the only Gerry Anderson–produced television series that was not of the fantasy or science fiction genres. It was produced by Lew Grade's ITC Entertainment production company. Despite not featuring marionettes or any real science fiction elements, The Protectors became one of Anderson's most popular productions, easily winning a renewal for a second series. A third series was in the planning stages when the show's major sponsor, Brut, ended its funding and thus forced the series' cancellation.

The Protectors was first broadcast in 1972 and 1973, and ran to 52 episodes over two series, each 25 minutes long—making it one of the last series of this type to be produced in a half-hour format. It starred Robert Vaughn (of The Man from U.N.C.L.E. fame) as Harry Rule, Nyree Dawn Porter (co-star of The Forsyte Saga) as the Contessa Caroline di Contini, and Tony Anholt (later to star in Space: 1999 and Howards' Way) as Paul Buchet. Episodes often featured prominent guest actors.
