Chen Jingrun (Traditional Chinese: 陳景潤; Simplified Chinese: 陈景润; pinyin: Chén Jǐngrùn, May 22, 1933 – March 19, 1996) was a leading mathematician from Fuzhou, Fujian, China. Asteroid 7681 Chenjingrun was named after him.

Chen was the third son in a large family. His father was a postal worker. Chen Jingrun graduated from the Mathematics Department of Xiamen University in 1953. His advisor at Chinese Academy of Sciences was Hua Luogeng.
His work on the twin prime conjecture, Waring's problem, Goldbach's conjecture and Legendre's conjecture led to progress in analytic number theory. In a 1966 paper he proved what is now called Chen's theorem: every sufficiently large even number can be written as the sum of either two primes, or a prime and a semiprime (the product of two primes) — e.g., 100 = 23 + 7·11.
