Rafael "Rafa" Nadal Parera (Spanish pronunciation: ) (born 3 June 1986) is a former World No. 1 Spanish professional tennis player, currently ranked #2. Nadal has won six Grand Slam singles titles, and the 2008 Olympic gold medal in singles.

Nadal was ranked World Number #1 from 18 August 2008 to 5 July 2009. In 2008, he became the first player to simultaneously hold Grand Slam titles on clay, grass and hardcourt. His success on clay has earned him the nickname "The King of Clay".

Nadal was ranked World No. 2, behind Roger Federer for a record 160 weeks before earning the top spot. He has subsequently lost this position again to Federer following the Swiss player's triumphs at the 2009 Madrid Open (where Federer beat Nadal in the final), the French Open and Wimbledon, as well as Nadal's own withdrawal from Wimbledon due to injury. In 2008, Nadal was given the Prince of Asturias Award for Sports, in recognition of his achievements in tennis.
