Robert Baddeley Simpson (3 February 1936 – 16 August 2025), known as Simmo, was an Australian cricketer who played for New South Wales, Western Australia and the Australian national team. He captained the Australian team from 1963 68 and again in 1977/78. He later had a highly successful term as the coach of the national team.
An outstanding fielder with the highest catch rate in Tests, Simpson was a top-level right-handed batsman and semi-regular leg spin bowler. After ten years in retirement, he returned to the spotlight at age 41 to captain Australia during the era of World Series Cricket.
In 1986, Simpson was appointed coach of the Australian team, a position he held until being replaced by Geoff Marsh in July 1996.
