If Siobhán McSweeney hadn’t already earned her status as a national treasure, her standout performance as host of The Traitors Ireland this year has unquestionably sealed it. The show was the most talked about of the year, but also the most watched, and adored, with McSweeney as its fulcrum with equal light and also plenty of shade too.
But it was a gamble, as many adaptations of successful shows elsewhere can fall flat when the cultural context is gone. For this proud Cork woman, though, you get the feeling she chooses her projects with great consideration, as well as understanding where her strengths lie. Acting was, she says, always her first love, yet she secured a degree in science at UCC (albeit to abate her parents’ concerns over her unconventional career choice) and in 2001, left Cork for London, training at the Royal Central School of Speech & Drama in London and then at the renowned École Philippe Gaulier in Paris.
Her film debut came in 2006 in The Wind That Shakes the Barley, and she began to build a rich career in theatre, film and television, working in the Abbey Theatre in Dublin and the Royal Shakespeare Company. But it was her breakout role as Sister Michael in Derry Girls (2018-22), which brought her widespread recognition, garnered both critical acclaim and established her as a brilliant, distinctive comedic voice, rightly winning her a BAFTA for Best Female Comedy Performance.
McSweeney proved her depth and dexterity, diversifying between dramatic parts, voice-work and presenting. As the anchor of the popular pottery show The Great Pottery Throw Down, she demonstrated that her warmth, humour, and gentle presence perfectly fit the show’s comfort watch credentials.
But it was this year that was to become McSweeney’s biggest moment yet, when, in August 2025, the Irish edition of the hit reality show The Traitors Ireland hit our screens with McSweeney at its helm. And it was a perfect match. Her sardonic wit and assured (necessarily intimidating) presence were a mix made in heaven for a show that did the rare thing of being even more compelling than its original.
McSweeney’s appeal lies in her ability to combine sharp comic timing with emotional depth. And those “mischievous asides” could only be delivered from a refreshingly unconventional perspective on entertainment. But McSweeney’s talent goes beyond just the light, and she has rightly received particular praise for embodying strong female characters and for her willingness to speak out on issues of representation, authenticity and gender. As a host, she brings warmth, intelligence and subtle humour – qualities which have helped elevate her 2025 hosting role into a signature moment of her career.
Off the screen, McSweeney has shown herself to be a champion of Irish talent and culture, returning to her origins in theatre, promoting home-grown stories, and leveraging her platform in television to highlight Irish voices in a global landscape. The transition from actor to presenter in 2025 signals her versatility and growing stature in her industry.
As our entertainment winner, we honour a figure who has not only delivered standout performances but who has evolved into a cultural force in 2025. Her hosting of a prime-time Irish reality series expands her impact beyond acting, while her earlier iconic role continues to resonate and inspire. She bridges comedy and drama, Ireland and the UK, screen and stage. Her professional journey – from science graduate to actor to broadcaster – is a testament to her bravery, adaptability and authenticity. This year has merely underscored McSweeney’s transformation: the shift into new arenas, national recognition, and a growing public platform.
