Johannes Petrus Jacobus 'Hansie' Graaff (born 10 September 1989 in Pretoria) is a South African rugby union player for Bayonne in the Top 14 in France.
He sprung to prominence playing for a struggling TUT Vikings side in the Varsity Cup between 2010 and 2012, scoring six tries in 21 appearances during the three seasons.
However, he was offered a contract extension with the Durban-based side until April 2014[6] and made his debut for them in the 2014 Vodacom Cup match against the Border Bulldogs,[7] marking the occasion by scoring a 10th minute try to help the Sharks to a 46–24 victory.
He joined Port Elizabeth-based side Eastern Province Kings prior to the 2014 Currie Cup Premier Division season.
He eventually made his debut for the EP Kings in a domestic competition by starting their first match of the 2015 Vodacom Cup season, a 19–27 defeat to defending champions Griquas.
