Adam Craig Gilchrist (; born 14 November 1971) is an Australian cricket commentator and former international cricketer and captain of the Australia national cricket team. He was an attacking left-handed batsman and record-breaking wicket-keeper, who redefined the role for the Australia national team through his aggressive batting. Widely regarded as one of the greatest wicket-keeper-batsman in the history of the game, Gilchrist held the world record for the most dismissals by a wicket-keeper in One Day International (ODI) cricket until it was surpassed by Kumar Sangakkara in 2015 and the most by an Australian in Test cricket.
