Greg Dyer, Australian cricketer
Gregory Charles Dyer (born 16 March 1959) is a former New South Wales and Australian wicketkeeper. Dyer played in six Tests and 23 ODIs from 1986 to 1988, including playing in the victorious 1987 World Cup Final. He toured India in 1986 as a back-up keeper.

Dyer replaced Tim Zoehrer for only a few Tests as his international career was cut short by the emergence of Ian Healy, along with a controversial incident in a Test match against New Zealand in 1987–88. Dyer claimed to have "caught" New Zealand batsman Andrew Jones who was duly given out, although television replays showed the ball had touched the ground before being caught by Dyer. He was subsequently dropped from the team two matches later and retired from first-class cricket shortly thereafter.He shares an Australian One Day International 7th-wicket partnership record with Steve Waugh.

In 2011, Dyer became the president of the Australian Cricketers Association.
