Du Jing (Chinese: 杜婧; pinyin: Dù Jìng; born June 23, 1984 in Anshan, Liaoning, China) is a badminton player from the People's Republic of China.
A doubles specialist, Du and her regular partner Yu Yang have steadily emerged as one of the world's elite women's doubles teams since 2004. They confirmed this status by winning the gold medal at the 2008 Olympics in Beijing over Korea's Lee Kyung-won and Lee Hyo-jung. Their other titles have included the Polish Open (2004); the China Masters (2005); the Asian Championships and Swiss Open in 2006; the Russian, Hong Kong, and Indonesia Opens in 2007; and the French, Korea, and Singapore Opens in 2008. Du and Yu were bronze medalists at the World Championships in 2006, but were unable to play in the tourney's 2007 edition. They were runners-up at the prestigious All-England Championships in 2008, but avenged that loss by beating their All-England conquerors in the Olympic final.
