Li Na (born 26 February 1982) is a Chinese retired tennis player.
She achieved a career-high WTA ranking of world No. 2 on 17 February 2014. Over the course of her career, Li won nine WTA Tour singles titles including two Grand Slam singles titles at the 2011 French Open and 2014 Australian Open. Her rise to prominence came after those victories, which made her the first Grand Slam singles champion from Asia. Prior to this, she was the first player representing an Asian country to appear in a Grand Slam singles final, a milestone she achieved at the 2011 Australian Open. Li was also the runner-up at the 2013 Australian Open and 2013 WTA Tour Championships, a three-time quarterfinalist at Wimbledon and a semifinalist at the 2008 Beijing Olympic Games and 2013 US Open. Among her other most notable accolades, she was the first Chinese player to win a WTA tour title at the Guangzhou International Women's Open in 2004, the first to reach a Grand Slam singles quarterfinal at the 2006 Wimbledon Championships, and the first to break into the world's top ten. Her feats have sparked a major population growth of tennis players in East Asia, earning her the reputation as the region's tennis pioneer and trailblazer.
Li retired from professional tennis on 19 September 2014, at the age of 32. In 2019, she was inducted into the International Tennis Hall of Fame, becoming the first Asian-born player to receive this honor.
