Gregory John Norman (born 10 February 1955) is an Australian retired professional golfer who spent 331 weeks as world number one in the 1980s and 1990s. He won 88 professional tournaments, including 20 PGA Tour tournaments and two majors: The Open Championship in 1986 and 1993. Norman also earned thirty top-10 finishes and was the runner-up eight times in majors throughout his career. In a reference to his blond hair, size, aggressive golf style and his birthplace's native coastal animal, Norman's nickname is "the Great White Shark" (often shortened to just "the Shark"), which he earned after his play at the 1981 Masters.

Norman's business interests began during his playing career. He is the chairman and CEO of the Greg Norman Company, a global corporation with a portfolio of companies in fields including apparel, interior design, real estate, wine production, private equity and golf course design. Between 2021 and 2025, he was the CEO of LIV Golf Investments, a start-up company financed by Saudi Arabia's sovereign wealth fund; the LIV Golf Invitational Series of golf tournaments began in 2022.

Norman has donated to and established numerous charities and charity events, like the QBE Shootout which benefits the CureSearch for Children's Cancer fund. He became a Trustee of the Environmental Institute for Golf in 2004 and received the Golf Writers Association of America's Bartlett Award in 2008 for his charitable work.

Early life Norman was born in Mount Isa, Queensland, Australia to Mervin and Toini Norman. His mother was the daughter of a Finnish carpenter, and his father an electrical engineer. As a youth, he played rugby and cricket and aspired to be a professional surfer. His mother Toini, who had a single-figure handicap, taught the 15-year-old Norman how to play golf and allowed him to caddy for her at the Virginia Golf Club in Brisbane. Within about eighteen months, Norman went from a 27 handicap to a scratch handicap. In Townsville, Queensland, Norman attended Townsville Central State School (enrolled 1964) and then Townsville Grammar School then moved on to Aspley State High School on the north side of Brisbane.

Amateur career In June 1974, at the age of 19, Norman received media attention at the Queensland Open. The Canberra Times reported that "the young amateur Greg Norman" was one shot off the lead after the first round.

Professional career As of March 1975, Norman had turned professional. He served as assistant professional under Billy McWilliam OAM at Beverley Park Golf Club in Sydney, New South Wales. Shortly thereafter, in the same year, Norman started work as Charlie Earp's trainee in the Royal Queensland Golf Club pro shop, earning A$38 a week.

Australian and European Tours Norman's first four-round professional tournament was the 1976 South Coast Open at Bateman's Bay. In the first round, Norman shot a 68 (−3) to put him in a tie for fifth place, three back of David Good's lead. He followed it up with an even-par 71 to remain in the top ten. In the third round, he "jumped into the reckoning" with a two-under-par 69 which included five birdies on the back nine, one back of the lead. In the final round, he had a chance to win down the stretch but was "edged out" by Barry Burgess. His second tournament was at the following week's Queensland Open. Norman was well back of the lead entering Sunday but shot a final round 70 (−3) to finish in a tie for third. The next week he recorded another top-15 finish at the New South Wales Open. His fourth tournament was the West Lakes Classic held at The Grange Golf Club in Adelaide, South Australia. In the first round, Norman "upstaged his more experienced opponents" to shoot a "brilliant" 64 (−7) to take a three shot lead. In the second round, despite incurring three penalty strokes, Norman shot a four-under-par 67 to expand his lead to five shots. Norman followed it up with a 66 (−5) to create 10 shot lead. On Sunday, however, he had a "fluctuating" final round with six bogeys, six pars, five birdies, and one double-bogey for a 74 (+3). Though David Graham got within four shots Norman held on to win by five. Norman described the win as "unreal." He later said, "It's been a great experience and now I know what now to do − I think."

Norman joined the European Tour in the following year and had his first victory in a European event that same season at the Martini International at the Blairgowrie Club in Scotland. In 1980, Norman earned a sizable victory in the French Open, winning the tournament by ten shots. He won the Scandinavian Enterprise Open in Sweden with a course record of 64 in the final round. Later in 1980, Norman won the Suntory World Match Play Championship. Norman also won his first Australian Open that year, his first of five wins in that event.

In 1981, Norman finished in 4th place on his debut at the Masters in Augusta, finishing just three strokes behind the winner Tom Watson. Norman had a victory in the 1981 British Masters and he won his third Martini International tournament that year as well. In 1982, Norman was the leading money winner on the European Tour. He won three European events that year, including successfully defending his British Masters title. The following year, Norman joined the U.S. PGA Tour.

PGA Tour In June 1984, Norman won his maiden PGA Tour victory at the Kemper Open, winning by five strokes. He gained worldwide prominence two weeks later at the 1984 U.S. Open. Norman holed a dramatic 45-foot putt on the 72nd hole to force a playoff with former Masters champion Fuzzy Zoeller, so astonishing to all that Zoeller took his white golf towel and waved it in joking surrender. At the next day's 18-hole playoff, Zoeller would earn a 67–75 victory over Norman. He was able to put the defeat behind him with a victory at the Canadian Open the next month in July for his second win of the year.

In 1985, Norman won the Toshiba Australian PGA Championship and the National Panasonic Australian Open. He had two runner-up finishes in the U.S. PGA Tour that year, finishing tied for second place at the Canadian Open and at the Bank of Boston Classic.

In 1986, Norman's 11 worldwide victories that year included four wins in Australia and two regular PGA Tour events; the Panasonic Las Vegas Invitational and the Kemper Open (for the second time) but 1986 is remembered for the Norman Slam or the Saturday Slam. Norman held the lead for all four majors through 54 holes. This meant he played in the final group for every major and had perhaps the best chance in history of winning the single-season Grand Slam. However, the only major victory Norman earned that year was in the 1986 Open Championship at Turnberry.

At the 1986 Masters, Norman began the final round with a one-stroke lead which he maintained until he double-bogeyed the 10th. After making four consecutive birdies on holes 14 to 17, Norman was tied with Jack Nicklaus going to the 18th. Norman missed a par putt on the 18th that would have sent the two into a sudden-death playoff. At the 1986 U.S. Open at Shinnecock Hills, Norman again led after 54 holes. However, Norman faltered on the final day, finishing with a final round 75 placing him six strokes behind the winner, Raymond Floyd.

Norman finally broke through at the 1986 Open Championship for his first major title. Norman shot a second round of 63 on Friday at Turnberry, tying the record for the lowest ever round at the Open. Only 15 players broke par in the second round. Tom Watson described Norman's feat as "the greatest round ever played in a tournament in which I was a competitor." Norman survived the weekend's brutal conditions at Turnberry, with a final round of 69 to win The Open by five shots. After being presented with the Claret Jug trophy, Norman said: "Outside of Australia, Britain was the first place that accepted me as a professional golfer. To win my first Open in front of the British public is the greatest feeling ever." Norman was again in contention at the 1986 PGA Championship. He was in the lead on the final day, but shot a final-round 76 to finish 2 strokes behind the eventual winner, Bob Tway.

Norman's four wins in Australia in 1986 helped him to finish top of the Australian Order of Merit for the fifth time. He also topped the U.S. PGA Tour money list for the first time that year. In September 1986, Norman won the Panasonic European Open at Sunningdale Golf Club and the following month he had another victory in England, winning his third World Match Play Championship at Wentworth. Norman ended 1986 with eleven worldwide victories and was officially ranked number 1 in the brand new Official World Golf Rankings.

Norman endured another setback at the 1987 Masters. In his final round on the 18th green, Norman had a 20-foot putt for a birdie that would win the tournament. The ball trickled over the left lip of the cup, missing by millimetres. After Norman's par on the 72nd hole at Augusta, he found himself in a sudden-death playoff with Larry Mize and Seve Ballesteros. On the second playoff hole, with Ballesteros eliminated, Mize holed a 47-yard (140-foot) chip to win the tournament. Norman did, however, win the Australian Masters in February 1987 and the Australian Open later in the year by a record ten shots at Royal Melbourne Golf Club, beating the previous Australian Open record winning margin of eight strokes by Jack Nicklaus in 1971. Norman's 1987 victory at the Australian Open lifted him back above Seve Ballesteros to the top of the Official World Golf Ranking.

Norman had another four wins in Australia in 1988. In the U.S., Norman won the MCI Heritage Golf Classic at Hilton Head Island, South Carolina, in April 1988, inspired by a leukemia-stricken teenager who got his wish to meet Norman and watch him play. The teenage boy was only supposed to watch the golfer for two rounds, but Norman arranged for him to stay until the tournament's completion. After the tournament, Norman awarded the teenager with the trophy. He was inducted into the Sport Australia Hall of Fame in that year.

At the 1989 Masters, Norman missed a 12-foot par putt on the 72nd hole, which would have put him into a playoff with Nick Faldo and Scott Hoch. Norman had another chance at a major in 1989, this time at the Open Championship at Royal Troon. He played a final round of 64, starting his round with six straight birdies, forcing his way into a playoff with Mark Calcavecchia and Wayne Grady. Going into the final playoff hole, Norman and Calcavecchia were tied, but two successive bunker shots by Norman gave Calcavecchia the victory.

Norman won the Doral-Ryder Open and Memorial Tournament in 1990. He also missed the cut for the first time at Augusta National in the 1990 Masters. In the 1990 Open Championship at St Andrews, Norman began with two rounds of 66, leaving himself sharing the lead with Nick Faldo after 36 holes and the pair four shots ahead of the rest of the field. Faldo then shot a third round of 67, but Norman could only manage 76. Norman finished the tournament tied for sixth place, while Faldo won by five shots. Although 1990 was not Norman's strongest majors year, he finished at the top of the PGA Tour money list for the second time in his career and won the Vardon Trophy and Byron Nelson Award. Later that year, he won the Australian Masters in his home country for a final and record sixth time. After a career slump in the early 1990s, Norman turned to renowned coach Butch Harmon for help. Together, the two rebuilt Norman's game by solving mechanical problems that had crept into his swing. As a result of this training, Norman earned his second major at Royal St George's in the 1993 Open Championship. There, in ideal conditions, Norman defeated a leaderboard consisting of Nick Faldo, Bernhard Langer and Corey Pavin. Norman's final round 64 was the lowest score by a winner in Open history until Henrik Stenson's 63 at the 2016 Open Championship.
