Bryn Terfel Jones CBE (Welsh pronunciation: ; born 9 November 1965) is a Welsh bass-baritone opera and concert singer. Terfel was initially associated with the roles of Mozart, particularly Figaro and Don Giovanni, but has subsequently shifted his attention to heavier roles, especially those by Wagner.

Bryn Terfel Jones was born in Pant Glas, Caernarfonshire, North Wales, the son of a farmer. His first language is Welsh. He knew of another Welsh baritone named Bryn Jones, so chose Bryn Terfel as his professional name. He had an interest in and talent for music from a very young age. A family friend taught him how to sing, starting with traditional Welsh songs. After winning numerous competitions for his singing, he moved to London in 1984 and entered the Guildhall School of Music and Drama where he studied under Rudolf Piernay. (He has recorded that he initially applied to the music college in Cardiff but when the reply was addressed to "Miss Terfel" he was so annoyed that a Welsh college did not know Bryn was a man's name that he switched to London.) He graduated in 1989, winning both the Kathleen Ferrier Memorial Award and the Gold Medal. The same year he came second behind Dmitri Hvorostovsky in the Cardiff BBC Singer of the World Competition, but won the Lieder Prize.
