Dirk Peter Viljoen (born 11 March 1977, in Enkeldoorn – now Chivhu) is a former cricketer who played 2 Tests and 53 One Day Internationals for Zimbabwe.
An allrounder, Viljoen bowled slow left arm orthodox and batted in the middle order, left-handed.
Viljoen debuted for Zimbabwe in Sharjah during the 1996/97 season, playing a One Day International against Sri Lanka.
Back home in Zimbabwe he found form with the bat, scoring hismaiden first class half century, an innings of 92 for Mashonaland A against Matabeleland in Bulawayo.
England toured Zimbabwe in February 2000 for some ODI games and although Viljoen failed to contribute much with the bat he impressed with the ball, taking 3 wickets in the final match.
Viljoen's finest innings with the bat in international cricket came at the site of his debut, in Sharjah and against the same opponents in Sri Lanka.
After moving to Midlands for the 2001/02 domestic season he became their stand-in captain when Douglas Marillier was playing for Zimbabwe.
