Rhydian Roberts (born 14 February 1983), popularly known as Rhydian, is a classically trained Welsh baritone, crossover artist, musical theatre actor and television presenter. He rose to fame after finishing as runner-up on The X Factor in 2007.
Of his four albums, the first went platinum, and the second included collaborations with Kiri te Kanawa and Bryn Terfel. The third, Waves, marked a shift in style from opera to pop, and Caneuon Cymraeg ("Welsh Songs") was released to tie in with his debut television series for the Welsh-language channel S4C.
Rhydian has completed two solo UK tours and made gala and charity appearances in Wales and at the Royal Albert Hall, London. He is an ambassador of The Prince's Trust. While his concert appearances have been centred mostly in Wales since 2011, he tours widely in musical theatre. He has starred in a European arena tour of The War of the Worlds - Alive on Stage! and UK tours of We Will Rock You, Grease, and The Rocky Horror Show.
