Wang Nan holds the record for the most women's singles titles at the World Table Tennis Championships, with four.
She won the world singles championship in 1999, 2001, 2003 and 2005. Her first title came in Eindhoven, Netherlands, and her fourth came in Shanghai, China. Wang's run placed her among the most successful female players in the history of the sport.
Wang also won Olympic women's singles gold at Sydney 2000 and Olympic doubles gold at Sydney 2000 and Athens 2004. At the world championships, she combined singles success with doubles and team titles, making her medal record broader than the singles statistic alone.
The record is sometimes confused with the number of Olympic singles titles: Wang won one Olympic singles gold, while Deng Yaping won two. The question concerns the individual women's singles event at the World Championships, not team or doubles competition.
