The "Traitors" refers to a small group of contestants in the reality competition shows called "The Traitors" (British, American versions) or "Celebrity Traitors." These Traitors are chosen at the start of the game to secretly work against the other contestants (known as the Faithful) by trying to eliminate or "murder" them during the competition to win the prize fund for themselves. In the latest 2025 BBC One series "Celebrity Traitors UK," the Traitors are Jonathan Ross, Cat Burns, and Alan Carr, who have covertly been designated to eliminate other contestants while trying to avoid suspicion from the rest of the group (the Faithful).

Similarly, in the American and British versions of "The Traitors," a select few contestants become Traitors with a mission to undermine and outlast the other players.

So, the Traitors are the identified contestants who are playing the hidden antagonist roles in these specific reality game show formats. In the current Celebrity Traitors (2025) UK show, those are Jonathan Ross, Cat Burns, and Alan Carr.
