Ian Harold Woosnam OBE (born 2 March 1958) is a Welsh professional golfer.
Nicknamed 'Woosie', 'Woosers', or the 'Wee Welshman', Woosnam was one of the "Big Five" generation of European golfers, all born within 12 months of one another, all of whom have won majors, and made Europe competitive in the Ryder Cup. His peers in this group were Seve Ballesteros, Nick Faldo, Bernhard Langer, and Sandy Lyle.
Woosnam was born in the town of Oswestry, Shropshire in England, and his family lived in the nearby village of St Martin's in Shropshire. He started playing at the unique Llanymynech Golf Club, which straddles the Wales-England border. He is short for a male golfer at 5 ft 4½ in (1.638 m), but he is a powerful hitter. He played as an amateur in regional competitions in the English county of Shropshire alongside Sandy Lyle.
