Paul Rhys (born 19 December 1963) is a Welsh actor with an extensive career in theatre, radio, television and film. Rhys was born in Neath to working-class Catholic parents, Kathryn Ivory and Richard Charles Rhys, a labourer. He is of part-Irish descent on his mother's side. From the age of ten, he bred and trained horses, becoming a highly accomplished rider. A committed punk during his youth, Rhys sang in several bands. His first acting job was playing Liverpudlian judo expert Ralph in John Godber's hit play Bouncers, before leaving for London, where he qualified for his Equity card by singing jazz standards at lunchtime for Peter Boizot's Pizza Express and Kettners.

Rhys received a Bernard Shaw Scholarship to study at RADA. In the first term he was spotted by Philip Prowse and was invited to perform in Oscar Wilde's A Woman of No Importance at the Glasgow Citizens Theatre, playing the illegitimate son, Gerald. He also appeared as Dean Swift in Julien Temple's film Absolute Beginners. Rhys completed his education at RADA by winning the William Pole prize and the Bancroft Gold Medal.
