Kathryn Thomas (born 1 January 1979) is an Irish television presenter.
Thomas attended the national school on the Green Road, Carlow and began her secondary school years in St Leo's College, Carlow. In her second year, she transitioned to The King's Hospital in Dublin as a boarder.  She studied Arts (English, Sociology and Information Studies) at University College Dublin but left before finishing as she won a contract to present the children's television programme Rapid. She also took London Guildhall acting exams to Grade 8.
Thomas worked on the television series No Frontiers, which included assignment stories about boomeranging in Australia, bungee jumping in New Zealand, child trafficking in Namibia, and American football.
In 2011, she became the new presenter of Operation Transformation on RTÉ One. In 2016 she will be replaced by Ray D'Arcy. In August 2011, it was announced that she would host the Irish version of The Voice, The Voice of Ireland.
In February 2012, Thomas stormed the stage during a performance by Alabama 3 at the 9th Irish Film & Television Awards, and wagged her finger at the rock band after they sang a song with the lyrics "fuck the police". She accused Alabama 3 of inciting people to violence.
Thomas revealed in 2015 that a series of shooting stars inked on the inside of her lower left arm were not tattoos but were in fact transfers. 
in April 2015 she set up Pure Results Bootcamp, a seven-day diet and exercise camp operating out of Inish Beg Island, a private Island Estate in West Cork, Ireland. The camp programme includes a pre-camp consultation with a nutritionist to establish the participants goals, a shared room in a courtyard cottage, a two-week post camp fitness and diet programme and two weekly weigh-ins with a member of the Pure Results Bootcamp team. 
In February 2012, she came third in a poll to find Ireland's most desirable Valetines.
