Werner Greeff (born 14 July 1977 in Bellville, Western Cape) is a former South African rugby union player.
He played for Western Province in the Currie Cup and for the Stormers in the Super 14 until a neck injury forced him into retirement in January 2007.
Just before full-time they launched a last, desperate counter-attack which concluded with Werner Greeff hitting the Australian defence at full speed on a perfect angle and powering his way over the line for a try that levelled the scores; with the last kick of the match, he then converted his own try to give South Africa a dramatic win.

He was named in the Stormers' squad for the 2007 Super 14, but, after playing in a pre-season warm-up game against a Boland team, continuing concerns about the neck injury forced him to announce his retirement from rugby on 22 January 2007.
