Elton Thomas Jantjies (born 1 August 1990) is a South African professional rugby union player who plays as fly-half.
In June 2014 it was reported that Jantjies had signed a contract with Japanese side NTT Communications Shining Arcs who play in the Top League.
Jantjies gained a reputation as being a clutch performer after he successfully converted every goal attempt in the 2011 Currie Cup final, a match in which the Golden Lions defeated the Sharks 42–16.
It was reported that he spent a night away from the team at a separate hotel during the test series against New Zealand (a highly unusual practice for athletes) where patrons allegedly heard the two having sexual encounters and then arguing.
He is reported as having: '... spent 10 minutes banging on the toilet door of an Emirates Airlines flight from Dubai until his fists bled.
A fellow passenger alleges that Jantjies could be heard saying “Komaan, my skat (Come on, my darling)”, to an air hostess hiding in the cubicle.'
