Simon Hewitt Cook (born 29 January 1972) is an Australian former cricketer. After graduating from the Australian Cricket Academy, he debuted for Victoria early in 1993. He showed promise in the 1993–94 season, taking 30 wickets at 29.5. He moved to New South Wales in the 1995–96 season. He was a surprise selection in two Test matches against New Zealand late in 1997, despite being considered by some to be not even up to first-class standard. On his debut, he took five wickets in the second innings against New Zealand in Perth.
