Pieter Willem Gabriel Rossouw (born 3 December 1971 in Swellendam in the Western Cape Province) is a former South African rugby player and current coach.
Rossouw played wing for Western Province in the Currie Cup and the Stormers in the Super Rugby competition.
He played a total of 43 times for the Springboks, making him one of the most capped Springbok wingers after South Africa's readmission to international rugby.
He was also one of South Africa's most prolific try-scoring wingers, post-isolation, with only Breyton Paulse(26) and Bryan Habana(53) scoring more tries.
He is 7th on the all-time try-scoring list for the Springboks.
Rossouw is currently the backline coach of the Bulls in Super rugby and the Blue Bulls in the Currie Cup.
He was known as "Slaptjips" (Afrikaans for potato chips or french fries), apparently because the sight of his running legs was like potato chips slapping together.
Pieter is the older brother of Chris Rossouw, who played flyhalf for Western Province and the Free State Cheetahs.
