Ken Doherty is an Irish professional snooker player, commentator and radio presenter.

As an amateur, Doherty won the Irish Amateur Championship twice, the World Under-21 Amateur Championship and the World Amateur Championship. Since turning professional in 1990, Doherty has won six ranking tournaments, including the 1997 World Snooker Championship in which he defeated Stephen Hendry, inflicting Hendry’s first loss in a world final. This victory made him the first and only player to be world U-21, world amateur and world professional champion. He came very close to breaking the Crucible curse, reaching the 1998 final where he lost out to John Higgins. He reached a third final in 2003, in which he was defeated by Mark Williams. In other triple crown events, he has been runner-up three times in the UK Championship and twice in the Masters.

An intelligent tactician, Doherty has compiled more than 350 century breaks in professional competition. Since 2009, he has combined his playing career with commentating and punditry work.
