The comedian takes over from David Walliams, who hosted the ceremony in 2020.
The Masked Singer presenter and comedian Joel Dommett will host this year's National Television Awards live from London's O2 on 9th September.
Joel said: "It’s a huge honour to be hosting the NTAs this year! It still feels like someone has made a wonderful error. I really, really love TV and can’t wait to celebrate the best stuff from what’s been a very weird year or so...
He continued: "I’m also really hoping The Masked Singer wins something so I can present an award to myself. That’s a creative narcissist’s DREAM!"
NTAs producer Kim Turberville said of Joel’s appointment as host: "There is a wealth of great television to recognise and we are delighted to have Joel at the helm. With his wit and natural charisma, he’ll definitely be bringing a fresh approach to this year’s awards."
