Peter Hanson (born 4 October 1977) is a Swedish professional golfer who has played on the European Tour and PGA Tour. Hanson was born in Svedala, Sweden. He turned professional in 1998 and has played on the Challenge Tour and the European Tour. His professional wins include the 1998 Gunther Hamburg Classics on the Challenge Tour and the 2005 Open de España on the European Tour. He has since won four more titles on the European Tour. He was a member of the Continental Europe team at the 2005 and 2007 Seve Trophy. He has featured in the top 20 of the Official World Golf Ranking and has consistently finished in the top twenty of the European Tour Order of Merit since 2007. His best position on the Order of Merit occurred in 2012 when he placed 4th. On 27 March 2012, Hanson accepted an invitation to join the PGA Tour for the remainder of 2012 with Special Temporary Membership status.Hanson recorded his best finish at a major championship in April 2012, when he finished tied for third at the Masters. After shooting a seven under round of 65 in the third round, Hanson was the sole 54 hole leader at 9 under par with a one stroke advantage heading into the final round. However his final round started badly with two bogeys in the opening three holes and he never recovered shooting a one over par round of 73 to finish in a tie for third. On 9 September 2012, Hanson won for the fifth time on the European Tour, taking victory at the KLM Open in The Netherlands. He began the final round a shot outside of the lead and it had looked like his chances were over after a wayward tee shot on 16 left him trouble, but he managed to escape with a par to trail Pablo Larrazábal by a single stroke. Then, after Larrazábal bogeyed the 16th, Hanson prevailed by two strokes courtesy of a long range eagle putt on the par-five 18th. The win was even more remarkable because Hanson almost withdrew from the event after his one-year-old son Tim was taken to hospital prior to the event starting.Hanson played on the PGA Tour in 2013.
