Wayne Mardle (born 10 May 1973) is an English former professional darts player who played in events of the Professional Darts Corporation (PDC) and British Darts Organisation (BDO). He was runner-up in three PDC majors, losing to Phil Taylor on each occasion. He was also a five-time world semi-finalist. He currently works as a pundit and commentator. He has been known as "Hawaii 501" since 2000, a play on the title of the popular television series Hawaii Five-O, due to the Hawaiian shirts he started wearing in 1998 for a bet, and 501 being the start score of a leg of darts. This dress sense coupled with his crowd-pleasing onstage activity (such as dancing to the interval music) saw him become one of the most popular players on the circuit.
