Elin Maria Pernilla Nordegren (Swedish pronunciation: [ˈeːlɪn ˈnɔɖəɡreːn]; born January 1, 1980) is a former Swedish model and the ex-wife of professional golfer Tiger Woods.

Nordegren was born in Stockholm, Sweden. Her mother, Barbro Holmberg, is a politician and the former Swedish migration and asylum policy minister, and the current Governor of Gävleborg County. Her father, Thomas Nordegren, is a radio journalist who served as a bureau chief in Washington, D.C. She has an older brother, Axel, and a twin sister, Josefin. Nordegren and her sister worked odd summer jobs and as cashiers in supermarkets to finance their studies. She started modeling in 2000, and appeared on the cover of Cafe Sport magazine in the summer of 2000.

Nordegren took a job in a Stockholm clothing store called Champagne, where she met Mia Parnevik, wife of Swedish golfer Jesper Parnevik, who hired Nordegren as the nanny to their children, a job that required her to move to the U.S. He introduced her to Woods during the 2001 Open Championship. Parnevik also is being quoted as having said, "I'm kind of filled with sorrow for Elin since me and my wife are at fault for hooking her up with him, and we probably thought he was a better guy than he is." [People Magazine] Previously, Woods had asked for a year to be introduced to Nordegren, who was seeing someone else at the time. "She had no interest in Tiger and he was OK with that," Mia Parnevik said. "There was a big line of single golfers wanting to meet her. They were gaga over her." She had hopes at the time of becoming a child psychiatrist. In November 2003, Woods and Nordegren attended the Presidents Cup tournament in South Africa and became officially engaged when Woods proposed at the luxury Shamwari Game Reserve.

Eldrick Tont "Tiger" Woods (born December 30, 1975) is an American professional golfer whose achievements to date rank him among the most successful golfers of all time. Formerly the World No. 1, he is the highest-paid professional athlete in the world, having earned an estimated US$90.5 million from winnings and endorsements in 2010.

Woods turned professional in 1996, and by April 1997 he had already won his first major, the 1997 Masters. He first reached the number one position in the world rankings in June 1997. Through the 2000s, Woods was the dominant force in golf, spending 264 weeks from August 1999 to September 2004 and 281 weeks from June 2005 to October 2010 as world number one. From December 2009 to early April 2010, Woods took leave from professional golf to focus on his marriage after he admitted infidelity. His multiple infidelities were revealed by several different women, through many worldwide media sources. This was followed by a loss of form, and his ranking gradually fell to a low of #58 in November 2011. He snapped a career-long winless streak of 107 weeks when he captured the Chevron World Challenge in December 2011. As of April 8, 2012, he is ranked #8.
