Nathan Andrew Green (born 13 May 1975) is an Australian professional golfer.
Born in New South Wales' second-most-populous city, Newcastle, Nathan Green turned professional in 1998. During his early career, he played mostly on the PGA Tour of Australasia, and the Canadian Tour during the Australian winter. In 2000 he won the Queensland PGA Championship in Australia, and the Benefit Partners/NRCS Classic in Canada.
Having failed to gain his PGA Tour card through the qualifying school, Green competed on the second tier Nationwide Tour in the United States in 2002, 2004 and 2005. He ended the 2005 season 18th on the money list, which enabled him to graduate directly to the PGA Tour for 2006. He finished 5th in his first event on the PGA Tour, and in his second, the Buick Invitational, he made his way into a playoff for the title against Tiger Woods and José María Olazábal, but was eliminated at the first extra hole. He finished the year ranked inside the top 50 on the money list.
Green's first PGA Tour victory came at the 2009 RBC Canadian Open where he defeated Retief Goosen on the second hole of a sudden-death playoff. Green almost lost on the first hole but Goosen missed a six-foot birdie putt that would have won the tournament. On the second hole, Green missed a twelve-foot birdie putt to win the tournament but it would not matter. Goosen had to sink a nine-foot par putt to extend the playoff but he missed it, giving Green the victory.[2]
After Green's exemption expired, he earned his PGA Tour card through Q School, but only finished 163rd on the 2012 money list. He split the 2013 season between the PGA Tour and Web.com Tour. Green has not played a PGA Tour-sanctioned event since 2015, instead choosing to compete on the PGA Tour of Australasia.
