Ni Zhiqin (; born 14 April 1942) often referred to as Ni Chih-Chin, is a retired Chinese high jumper.
He is known for breaking the world record with 2.29 m on 8 November 1970 in Changsha, but because PR China was not a member of the International Association of Athletics Federations at the time, his record was never ratified.
