The Traitors (also known as The Traitors UK outside of the UK) is a British reality television series broadcast on BBC One, based on the Dutch series De Verraders, which premiered on 29 November 2022 and is hosted by Claudia Winkleman.

Following the premise of other versions of De Verraders, the show features a group of contestants participating in a game similar to the party game Mafia in the ground of a historic Scottish Castle. A small group of contestants become the titular "Traitors", and must work together to eliminate the other contestants in order to win a grand prize, while the remaining contestants become "Faithful" and are tasked to discover and banish the Traitors by voting them out, to win the grand prize.

After the first episode aired on BBC One, it and the next two episodes were uploaded onto BBC iPlayer, with each subsequent episode being available on BBC One only, before being uploaded one at a time to iPlayer.

On 27 February 2023, the BBC announced that the show had been renewed for a second series, with Winkleman returning to host. On 3 November 2023, it was revealed that a third series had been commissioned, as well as a celebrity version in the works. On 22 August it was announced that the series has been renewed for a fourth series with a celebrity edition also commissioned.
