The Traitors Ireland
Irish reality TV series

The Traitors Ireland is an Irish reality television series broadcast on RTÉ One and streams on RTÉ Player.The first season aired on 31 August 2025, and is based on the Dutch series De Verraders. It is presented by Siobhán McSweeney.
Following the premise of other versions of De Verraders, the show features a group of contestants participating in a social deduction game similar to Mafia or Werewolf, as they stay in a historic castle. During their stay, a small group of contestants become the titular "Traitors", and must work together to eliminate the other contestants 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 of up to €50,000. The second series premiered on the 30th of August 2026.
Format
Over twenty contestants arrive at a castle in Meath where they will spend their entire time for the duration of the game (although they sleep off site). On the arrival day, host Siobhán McSweeney picks at least three contestants to be called "Traitors" and the rest are automatically called "Faithful". The television audience can see who have been chosen as Traitors, but the Faithful do not know their identity.
Each night, the Traitors come together and decide upon one Faithful contestant to "murder" – and that person will leave the game immediately. The remaining Faithful contestants will not know who has been eliminated until the following day, when they do not arrive for breakfast.

Why this record matters
“The Traitors Ireland” is worth following because a concise public description often conceals a longer documentary argument. Here, Traitors, Ireland and Irish provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q136206165. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2025 and 2026.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
