Cast of the Traitors – Complete Guide to Every Season

The Traitors has become one of the most talked-about reality franchises since its debut in 2022. With multiple versions airing across the UK and US—and a celebrity spin-off drawing household names—audiences are increasingly searching for clear, complete cast lists. This guide covers every season of The Traitors, including the UK and US editions, the Celebrity Traitors line-ups, and the hosts who steer the game.

The show, based on the Dutch series De Verraders, blends psychological strategy with social deduction. Contestants are divided into Faithfuls and Traitors, with the latter secretly eliminating players each night. The format has proven flexible enough to accommodate both civilian contestants and celebrity participants, each bringing a different dynamic to the castle.

As of May 2026, the franchise includes three UK civilian seasons, four US civilian seasons, and two UK Celebrity editions. The US version has also featured celebrity casts within its regular seasons. Below is the full breakdown of who has appeared, who hosts each version, and how the casts compare. For a complete overview of the American line-ups, check the The Traitors US cast guide.

Franchise Snapshot

Who Hosts The Traitors?

The hosting duties are split between two very different personalities. In the UK, Claudia Winkleman presents the show with her signature warmth and dramatic flair. She has been the face of the UK version since its first season in 2022, guiding contestants through the psychological twists with a measured, empathetic tone.

Across the Atlantic, Alan Cumming brings a theatrical edge to the US version. Described as “impossibly stylish and witty,” he hosts all US seasons with a campy, mischievous energy that matches the show’s high-stakes betrayal theme. Cumming’s presence has become a defining element of the American edition, and he has hosted all four US seasons to date.

Does the UK Version Have a Different Host?

Yes. The UK version is presented exclusively by Claudia Winkleman, while the US version is hosted by Alan Cumming. No other host has been attached to either edition as of May 2026. The IMDB page for The Traitors UK lists Winkleman as the sole presenter, and the US equivalent confirms Cumming in the same role.

What Is the Cast of The Celebrity Traitors?

The UK Celebrity Traitors is a spin-off of the main series, in which well-known public figures compete for charity. The format mirrors the civilian version, with Faithfuls and Traitors playing out the same psychological game. As of May 2026, two series have been produced.

How Do the Casts of The Traitors UK and US Compare?

The UK and US versions of The Traitors share the same fundamental format but differ significantly in their casting approach. The UK civilian seasons have typically featured everyday people from a variety of backgrounds. The US version, meanwhile, has increasingly drawn from the pool of reality TV veterans, with contestants who have previously appeared on shows like Big Brother, Survivor, and The Real Housewives.

For example, US season 4 included an eclectic mix of reality competition winners, Real Housewives cast members, ex-Bachelor contestants, comedians, and former Olympians. One notable participant was Tiffany Mitchell, who won America’s Favorite HouseGuest on Big Brother Season 23 and also competed on The Challenge: USA. The Wikipedia page for The Traitors US season 4 provides a full list of contestants.

Are the Casts of the UK and US Versions the Same?

No. The casts are entirely separate, and no contestant has crossed over between the two versions. The shows are produced independently—the UK version by the BBC, the US version by Peacock—and feature different hosts, locations, and contestant pools. The UK series films at Ardross Castle in Scotland, while the US version has also used the same location for some seasons.

What Is Confirmed and What Is Not Known About The Traitors Casts?

Why Is the Cast of The Traitors So Widely Searched?

The psychological game of trust and betrayal at the heart of The Traitors generates strong audience interest in the characters who play it. Each contestant brings a unique personality and strategy, and viewers naturally want to know who is playing, who was eliminated, and who won. The UK version started with civilians, which made the cast relatable and unpredictable. The celebrity edition then boosted viewership by adding known personalities from television, music, and sport.

In the US, the reliance on reality TV alums and game show veterans creates a different dynamic entirely. Contestants like Cirie Fields (a Survivor legend) and Rob Mariano (also from Survivor) bring pre-existing fan bases and strategic reputations. This blend of familiar faces and high-stakes gameplay makes the cast a frequent topic of online searches, especially as each new season begins.

Where Can I Find Official Cast Lists for The Traitors?

The most authoritative sources for cast lists are the official broadcaster announcements and publicly maintained databases. The BBC Media Centre provides confirmed line-ups for the UK Celebrity Traitors editions. For the US version, Wikipedia offers detailed season-by-season cast information, including winners and notable contestants.
