Jacques Potgieter (born 24 April 1986) is a South African rugby union player, currently playing with Fukuoka Sanix Blues in the Japanese Top League and the Waratahs in Super Rugby.
He represented Eastern Province at the annual Craven Week rugby tournament in 2004 and then clinched a move to the Natal Sharks, whom he represented at various youth levels before playing in the Vodacom Cup for two seasons before moving back to the Eastern Province Kings for the 2009 Currie Cup First Division season.
In August 2011, the Blue Bulls announced that they had signed Potgieter for the 2012 season on a two-year contract. An early release of his contract was secured and he joined the Bulls on 1 September.
He became a Springbok on 23 June 2012 against England during a test played at Nelson Mandela Bay Stadium.
In May 2013, it was revealed that he would leave the Bulls at the end of the 2013 Super Rugby season. He joined Japanese Top League side Fukuoka Sanix Blues – a deal later extended until 2017 – and would also play Super Rugby for the Waratahs in 2014 and 2015.
