Fort Boyard: Ultimate Challenge is a children's game show, based on the French show Fort Boyard, which aired on both CITV and Disney XD. The show is a challenge game where six different "fearless" teams of teenagers battle-to-the-finish to win the "Ultimate Challenge" and become the "Ultimate Conquerors Of The Fort". The show is a revived and updated version of the original format, broadcast in the UK from 1998 to 2003.

While being a commission from CITV in the UK, the first two series were produced as a British-American co-production with Disney XD, who held worldwide pay rights to the series outside France and Nordic territories, and was co-presented by Geno Segers and Laura Hamilton.

In the United Kingdom, it premiered on New Year's Day 2012 In the United Kingdom.

After the series was renewed for a third series in June 2012, the series became solely a British production, with Geno Segers being replaced with Andy Akinwolere as co-presenter.
