He Kexin (Chinese: 何可欣; pinyin: Hé Kěxīn [xɤ̌ kʰɤ̀ɕín]; born January 1, 1992 or 1994 in Beijing according to official records) is a Chinese gymnast. At the 2008 Olympics in Beijing she won gold medals on the uneven bars (her specialty) and as a member of the Chinese Artistic Gymnastics team. In 2008, she won two World Cup titles on the uneven bars. On the bars she was one of the few gymnasts in the world to score over 17.00 under the 2005–2008 Code of Points. With an A-score of 7.7 in 2008, she had one of the highest difficulty scores in the world in the event, along with Yang Yilin, Nastia Liukin and Beth Tweddle. As with several of her teammates, questions were raised in the international press when earlier reports surfaced indicating she may not have been old enough to compete in the 2008 Olympics, but an official investigation found in her favor.

He Kexin trained at the Shichahai Sports School in Beijing. She participated in China's National Games in 2006 and Intercity Games in 2007. According to China Daily, He was recruited for the Chinese National Team in 2007, after her uneven bars win at the Intercity Games drew the attention of head coach Huang Yubin.
