Mario Wickus Olivier (born 3 November 1982 in Pretoria) is a South African cricketer who played first-class cricket from 2005 to 2012.
In December 2007 he became the third South African to take 10 wickets in a first-class innings when he took 10 for 65 for Warriors against Eagles.[1] Eagles nevertheless won by 10 wickets, so Olivier took all their wickets that fell in the match. Five of his victims were out leg before wicket.[2]
