Zhang Ning (; born 19 May 1975) is a former Chinese badminton player. She won the Olympic gold medal twice for women's singles in both 2004 and 2008. She has played badminton on the world scene since the mid-1990s and has been particularly successful since 2002 while in her late twenties and early thirties, relatively late for singles at the highest level, and especially for top players in the Chinese system who are developed very early. She is known for her consistency of shot, deception and constant pressure, dictating the pace of rallies and working her opponents in all four corners of the court. She is the only female player to win consecutive Olympic singles gold medals. She also became World champion in 2003 and has a total of five medals of all colours in the competition. Zhang first represented China in the Uber Cup (women's world team championship) competition in 1994 and last represented it in 2006. Though she was not always chosen to play in each of the biennial editions of this tournament, the span of her Uber Cup service is the longest of any Chinese player. Career 2003 Although she had previously won a number of international open titles dating from the mid-1990s, Zhang's breakthrough as a dominant player on the world circuit came in the 2003 IBF World Championships, where she stormed into the final. There, 28-year-old Zhang Ning defeated compatriot Gong Ruina easily 11-6, 11-3. 2004 The following year, Zhang played badminton at the 2004 Summer Olympics for China. In women's singles, she defeated Marina Andrievskaya of Sweden and Kelly Morgan of Great Britain in the first two rounds. In the quarterfinals, Zhang beat Wang Chen of Hong Kong 9-11, 11-6, 11-7 to advance to the semifinals. There, she defeated countrywoman Zhou Mi 11-6, 11-4. Zhang defeated Netherlands's Mia Audina 8-11, 11-6, 11-7 in the final to win the gold medal. It was sweet revenge for the 29-year-old, who had lost to Audina 10 years earlier in the decisive match of the Uber Cup. With her Olympic win, she became one of three singles players in the world to win the World Championship and the Olympic Games (in either order) in successive years, the others being Susi Susanti and Taufik Hidayat. 2005 Zhang also claimed many titles after her breakthrough wins. She bested Xie Xingfang in the 2005 China Open 3-11, 11-4, 11-8, but in
