Lorena Ochoa Reyes (Spanish (help·info); born 15 November 1981) is a Mexican professional golfer who played on the U.S.-based LPGA Tour from 2003 to 2010. She was the top-ranked female golfer in the world for 158 consecutive and total weeks (both are LPGA Tour records), from 23 April 2007 to her retirement in 2 May 2010, at the age of 28 years old. As the first Mexican golfer of either gender to be ranked number one in the world, she is considered the best Mexican golfer and the best Latin American female golfer of all time. Ochoa was inducted into the World Golf Hall of Fame in 2017.
Born and raised in Guadalajara, Ochoa was the third of four children of a real estate developer and an artist. She took up golf at the age of five, won her first state event at the age of six, and her first national event at seven.
An 11-year-old Ochoa approached the professional Rafael Alarcon, 1979 winner of the Canadian Amateur Championship, as he worked on his game at Guadalajara Country Club, where her family lived near the 10th tee. She asked him if he would help her with her game. Alarcon asked her what her goal was, "She said she wanted to be the best player in the world."
