Dewald Pretorius (born 6 December 1977) is a South African cricketer.
He is a right-arm fast bowler who debuted for the South Africa national cricket team in the second Test against Australia during the 2001/2002 series.
Pretorius has also played, at county level, for the English sides Durham and Warwickshire, where he recorded career best List A figures of five wickets for 32 runs against Kent.
Pretorius achieved some notoriety during UK coverage of South Africa's 2003 Test series with England, because of his rather difficult and troubled childhood.
