Jason Neil Gillespie (born 19 April 1975) is an Australian cricket coach and former cricketer who played all three formats of the game. A right-arm fast bowler, he was also a competent lower-order batsman whose unbeaten 201 in his last Test match is the highest score by a night-watchman in international cricket.
Gillespie made his One Day International debut against Sri Lanka at Colombo in the Singer World Series in August 1996, and his Test debut against the West Indies at Sydney in November 1996. He also played for South Australia, Yorkshire and Glamorgan at first-class level, and was an AIS Australian Cricket Academy scholarship holder in 1995.
Gillespie announced his retirement from first-class cricket in Australia in February 2008. He then played in the unauthorised Indian Cricket League for the Ahmedabad Rockets. At the end of the 2008 English domestic season he retired from all first-class cricket.
