Jeux Sans Frontières was a Europe-wide television game show. In English-speaking countries, the show is also known as It's a Knockout, the title of the BBC's domestic version.

In its original conception, it was broadcast from 1965 to 1999 under the auspices of the European Broadcasting Union and featured teams from different European countries in outlandish costumes competing to complete bizarre tasks in funny games. The original series run ended in 1982 but was revived a few years later with a different complexion of nations and hosted by smaller broadcasters.

In the United Kingdom, participants came from the heats of It's a Knockout. The original presenter was Mcdonald Hobley, but he stayed for just one season before handing over to Katie Boyle, who in turn was replaced by David Vine and Eddie Waring. It was not until 1971 that the presenter most associated with the role, Stuart Hall, took over presenting the UK heats and also provided the British commentary for the international version along with Waring, who was better known as the BBC's Rugby League commentator. Wales had its own team between 1991 and 1994 and the programme was broadcast on S4C in Welsh by Iestyn Garlick.
