Michael Shane Campbell, CNZM (born 23 February 1969) is a New Zealand golfer who is best known for having won the 2005 U.S. Open and the richest prize in golf, the £1,000,000 HSBC World Match Play Championship, in the same year. He is a member of the European Tour.
Ethnically, he is predominantly Māori, from the Ngati Ruanui (father's side) and Nga Rauru (mother's side) iwi. He also has some Scottish ancestry, being a great-great-great-grandson of John Logan Campbell, a Scottish emigrant to New Zealand.
Campbell was born in Hawera, Taranaki. As a young child, he lived near his mother's Wai-o-Turi marae at Whenuakura, just south of Patea, and also spent much of his time with whanau at his father's Taiporohenui marae, near Hawera.
