Born in Dusseldorf, West Germany, Kaymer turned professional at age 20 in 2005 and is a member of the European Tour. He has won eleven tournaments on the tour including four in 2010 to win for the first time the Race to Dubai, formerly the Order of Merit. Among those wins was the PGA Championship in the United States, which made him only the second German (after Bernhard Langer) to win a major championship. He also won the WGC-HSBC Champions to become the tenth player to win both a major title and a World Golf Championship event.

In May 2014, Kaymer earned a wire-to-wire win at The Players Championship in Ponte Vedra Beach, Florida, finishing -13 for a one-shot victory over runner-up Jim Furyk. He started the week with a course record-tying 63 in the first round at the Stadium Course of TPC at Sawgrass, joining Fred Couples (1992), Greg Norman (1994), and Roberto Castro (2013). He played the front nine (his second nine) in 29 (-7). This was the first time ever, back or front nine, that a player shot below 30 through nine holes at The Players. The final round was delayed due to bad weather while Kaymer was playing the 14th hole. He holed a difficult 28-foot (8.5 m) par putt (with a huge downhill left-to-right-break) on the 17th green to retain his one-stroke lead. His approach shot on 18 was short of the green but he holed the winning putt for par in near darkness and avoided a three-hole playoff. He became the fourth European to win this event (Sandy Lyle in 1987, Sergio Garcia in 2008, and Henrik Stenson in 2009), and is the fourth to win a major, a World Golf Championship, and The Players, joining Tiger Woods, Adam Scott, and Phil Mickelson. Kaymer earned a winner's share of $1.8 million, the largest of his career, and re-entered the top 50 in the Official World Golf Ranking, rising 33 places from 61st to 28th.  In June, Kaymer started the U.S. Open at Pinehurst with consecutive rounds of 65 (-5) to set a U.S. Open record for 36 holes (130). He finished at 271 (-9), eight strokes ahead of runners-up Rickie Fowler and Erik Compton, and became the first player in history to win those two championships back to back. (Woods also held both titles concurrently, winning the U.S. Open in 2000 and The Players in March 2001; it moved to May in 2007.) With the win, Kaymer gained exempt status on the PGA Tour through 2019 and rose to eleventh in the world rankings. With his U.S. Open victory in 2014, Martin became the first non-British European golfer ever to win the U.S. Open, and one of few players to win two majors under the age of thirty.  In October 2014, Kaymer won the PGA Grand Slam of Golf, the annual 36-hole event featuring the year's four major champions.
