Michael Shane Campbell CNZM (born 23 February 1969) is a New Zealand professional golfer who is best known for having won the 2005 U.S. Open and, at the time, the richest prize in golf, the £1,000,000 HSBC World Match Play Championship, in the same year.

He was introduced to the game by an uncle, Roger Rei, but was also undoubtedly influenced by his father, Tom Campbell, who was a single-figure handicapper.

From 1988, Campbell represented New Zealand in various international amateur competitions, including the team victory at the 1992 Eisenhower Trophy, before turning professional in 1993.

In 1995, in his first full season on the European Tour, he held a two-shot lead after the third round of The Open Championship, but faded after a final-round 76.

In the end, Woods was undone by bogeys on the 16th and 17th holes, and Campbell won his first major by two shots, carding an even par of 280.

Two months later, in August, Campbell finished in a tie for 6th in the PGA Championship at Baltusrol, won by Phil Mickelson.

Campbell defeated Goosen 7 and 6 and the next day beat Irishman Paul McGinley 2 and 1 in the final to take the championship and win the £1,000,000 richest prize in golf.

Campbell had no top-10 finishes on the European Tour between 2009 and September 2012, although his U.S. Open win meant he retained his playing rights.

[8] He was unable to play in the New Zealand Open as planned, having aggravated an old injury to a tendon in his left ankle during training.

[2] In the 2001 Queen's Birthday Honours, Campbell was appointed an Officer of the New Zealand Order of Merit, for services to golf.
