Zhang Ning is a female badminton player from the People's Republic of China. 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.
Zhang first represented China in 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.
