Deshabandu Muttiah Muralitharan (born 17 April 1972) is a Sri Lankan cricket coach, businessman and former professional cricketer. Averaging over six wickets per Test match, he is widely regarded as one of the greatest players in the history of the sport. He is the only bowler to take 800 Test wickets and more than 530 One Day International (ODI) wickets. As of 2025, he has taken more wickets in international cricket than any other bowler. Muralitharan was a part of the Sri Lankan team that won the 1996 Cricket World Cup and the team which was joint-winners with India of the 2002 ICC Champions Trophy.
Muralitharan's international career was beset by controversy over his bowling action. Due to an unusual hyperextension of his congenitally bent arm during delivery, his bowling action was called into question on a number of occasions by umpires and sections of the cricket community. After biomechanical analysis under simulated playing conditions, Muralitharan's action was cleared by the International Cricket Council, first in 1996 and again in 1999.
