Gladiators is a British television game show centred around sports entertainment activities. It is an adaptation of the earlier American television programme and its format, American Gladiators. The British version was produced by London Weekend Television (LWT) for commercial television network ITV.

The programme's format sees four contestants, two male and two female, compete in a series of physically challenging events against the show's resident 'Gladiators', eventually competing in one final event. The contestants aim to secure a place in the grand final, and ultimately be crowned champion for their respective series. There were no prizes awarded to the winner in any episode, only in the grand final. Gladiators was presented by Ulrika Jonsson throughout its original run, alongside John Fashanu (1992–96, 1999–2000) and Jeremy Guscott (1997–98), with John Sachs providing commentary on each event, and John Anderson refereeing the contests. A group of cheerleaders also accompanied the show, known as the 'G-Force'.

The success of the British series itself spawned further adaptations in Australia and other countries as part of a franchise, while a children's spin-off version for the UK, entitled Gladiators: Train 2 Win, was also created and broadcast on the CITV strand between September 1995 and March 1998, along with a series of live arena shows. A revival of Gladiators was produced for satellite TV channel Sky1, broadcast between May 2008 and October 2009. On 13 January 2024, A second revival started broadcasting on BBC One and BBC iPlayer, presented by Bradley Walsh alongside his son Barney.
