Terry Griffiths (born October 16, 1947) is a retired Welsh snooker player. He is a former world champion, and is renowned for his slow, cautious style of play.
A former postman, Griffiths had a long amateur career, winning the Welsh Amateur Championship in 1975 and the English Amateur Championship in 1977 and 1978 before turning professional.
The virtually unknown Griffiths shot to fame during the 1979 world championships. Interviewed after beating Eddie Charlton in a long semi-final, it suddenly dawned on him what he had done, and he said "I'm in the final now, you know!" in his broad native accent. He went on to beat Dennis Taylor 24-16 in the final, becoming world champion at his first attempt. He never repeated this, although he reached the final in 1988, losing to Steve Davis. He has also won The Masters.
Griffiths retired from professional play in 1996, and is now coach to Marco Fu, Stephen Hendry and, until recently, Mark Williams. He also frequently commentates on snooker for the BBC, often alongside Dennis Taylor. His style of commentary is arguably far livelier than his snooker play and often gently digs at his co-commentators, especially Willie Thorne.
