SAS: Are You Tough Enough was a British documentary series exposing volunteer members of the public to the experience of the SAS selection process presented by Dermot O'Leary. On average only 10 out of the 125 soldiers taking the real SAS selection procedure pass. In contrast to the real SAS, this programme also featured female candidates. As with real selection, initially the candidates were pushed to the limits to reduce the numbers, with survivors in the latter stages, trained and assessed in a variety of military training exercises.

The contestants participated in exercises experienced in the real selection process, although over a shorter time frame, with the winner only getting a hand-shake from the ex-SAS SSgt Eddie Stone. For realism, exercises were controlled by ex-members of the SAS, notably Staff Sergeant Eddie Stone, with additional comments about what would happen in the real process from other ex-SAS members.

There were three series: the original in the Scottish Highlands, the SAS Jungle in Borneo, and SAS Desert in Namibia.
