The fourth series of The Traitors was first broadcast on BBC One on 1 January 2026. Claudia Winkleman returned to present the series, which was accompanied by the spin-off show The Traitors: Uncloaked, presented by Ed Gamble. The series concluded on 23 January 2026 when Rachel Duffy and Stephen Libby won, becoming the first pair of Traitors to win the British version.

Production In August 2024, prior to the beginning of the previous series, it was announced that The Traitors had been renewed for a fourth series. Applications for the series opened on 22 August 2024, before closing on 28 March 2025. Filming for the series began in June 2025. The first teaser for the fourth series aired at the end of the final of The Celebrity Traitors, which featured a figure wearing a Traitors' cloak carrying a lantern walking through a forest at night, whilst "Heart of Glass" played in the background. The series began on 1 January 2026.

Contestants The 22 contestants competing in the series were revealed at midnight on 1 January 2026, the day of the show's launch. Amongst the contestants were a mother and daughter, Judy and Roxy, and a couple, Ellie and Ross, none of whom revealed their relationships to the other players; Judy and Roxy's connection was revealed to the audience in the first episode, while Ellie and Ross's relationship was revealed to viewers only after Ross's banishment. Additionally, Netty and Ross were old acquaintances, who did not know each other would be present and were selected for the series independently; Netty exposed their connection to the other players upon their arrival.

In the first episode, Winkleman revealed that one contestant would be selected as a "Secret Traitor", whose identity would be hidden from both the audience and the regular Traitors. Each night, they would provide the Traitors with a shortlist of Faithful to murder. Contestants were therefore only initially identified as Faithful by appearing on murder shortlists selected by the Secret Traitor, or after being banished. In episode 4, the Secret Traitor was revealed to be Fiona to Traitors Stephen and Rachel after Hugo was banished. Prior to this, the Secret Traitor was visually represented on screen as an unidentified figure dressed in a red cloak.

Missions EpisodeTask descriptionTime limitMoney earnedMoney availableRunning totalShield winner(s)1In rowboats, three teams of players searched for coffins floating on Loch Glass with gold in them, transported them to shore and placed them in any of the graves named after contestants to add £1,000 to the prize fund. The players whose named graves remained empty were shielded from murder. 45 minutes £12,000£10,000(of £12,000)AmandaBenEllieHarrietHugoJackJadeJessieMatthewRoxySamStephen2Three throne-bearing chariots were pushed to the castle from the hills above, stopping three times to collect gold or shield tokens. Players seated on thrones at the castle were protected from murder, but those with a shield token could swap places to claim immunity.45 minutes £9,000£18,750(of £21,000)AmandaFaraazJade3The players were divided into two groups; twelve remained at the castle, with the remaining seven visiting the Old Gallery to compete for a shield. The castle featured six empty portrait frames, each with a descriptive plaque. The castle team had to recreate the scenes described, enabling the gallery team to identify the correct portraits. £1,000 was added to the prize fund for each correct match with one portrait concealing a shield.60 minutes £6,000£23,750(of £27,000)Adam4The players who were shortlisted for murder were placed in cages, with the remaining players choosing who they wanted to save. One shortlisted player did not have anyone trying to save them. The players outside the cages had to find ten skulls hidden around the area, and then stack them on a pedestal in order to save their player from murder, and to add £2,000 to the prize fund. Up to five players could be saved.30 minutes £10,000£33,750(of £37,000)AmandaFaraazJackJadeJames5All players had to search the forest for spears and use them to set fire to one of ten statues. When setting fire to a statue, the player doing so had to name a player who would then become eligible for murder that night. Players could name themselves but could not repeat a name. Each statue set on fire added £1,000 to the prize fund.30 minutes £10,000£42,750(of £47,000)AdamHarrietJackJamesJessieRachelRoxy6The players split into three teams; each team had to go through a forest and answer questions on mirrors that were based on questionnaires they had filled out the previous night. Correct answers added £500 to the prize fund. The team that got the most questions correct (if there was a tie, then the fastest answering team) won access to the walled garden, where each player selected a mirror to smash. Three of the mirrors would blow smoke after being smashed; the players who smashed the smoking mirrors won the opportunity to ask the traitors two questions each. £6,000£47,250(of £53,000)7In teams, players had to find eight cherub statues and place them around the edge of a fountain. Cherub coins in the water revealed the location of the statues. Each statue came with a shield which could be taken, but doing so deducted £1,000 each time from the winnings. All eight cherubs had to be found, otherwise no money or shields would be awarded.30 minutes £10,000£50,250(of £63,000)FaraazJackJadeJamesJessieRachelStephen8The contestants were taken to a cabin in the wood, where they were tasked with solving cryptic clues while they were subjected to various jump scares. After the team had solved the puzzle, revealing a name, one player would leave the cabin and had one minute to search a nearby graveyard for the grave with that name. If they found the correct grave, £1,000 would be added to the prize fund. There was also a single shield on offer, which a player could look for instead of finding the grave. Having left the cabin, the player would not return for the remainder of the mission. £6,000£54,250(of £69,000)Sam9The contestants were placed in boxes and asked questions about what the traitors thought about their fellow players. The traitors would have to get out of the boxes to decide the correct answer before returning to their box to answer as individuals. Each player who answered the questions correctly added £250 to the prize fund. £9,000£57,500(of £78,000)10Contestants were faced with the Carous-hell funfair, where they were spun on a carousel, then released to search for gold hidden in cuddly toys. Gold bags ranged from £250 to £2,000. Each successful return earned another spin, but seats were removed after every round, eliminating players. The last player seated was awarded a shield. £12,000 £66,750(of £90,000)Jack11Contestants ascended a hill to the Fyrish Monument, collecting gold rocks from shrines honouring the murdered faithful along the way. At the summit, they had to fill the Shield of Fyrish with the gold. If completed in time with all players present, £10,000 would be added to the prize fund and the traitors would be blocked from committing a final murder.45 minutes £10,000 £76,750(of £100,000)FaraazJackJadeJamesRachelStephen12The players split into two teams and were tasked with crossing a loch using speedboats to collect gold from a series of pontoons. A flare emitting green smoke indicated that gold was available, but if the smoke turned red before the players arrived, the gold became inaccessible. After collecting the gold, they had to return to Claudia by climbing a ladder to the top of a dam. An additional £10,000 was offered if they could descend the front of the dam and reach a waiting helicopter within five minutes.45 minutes £20,000£95,750(of £120,000)
