Chen Jingrun (ch.:陈景润, py.: Chén Jǐngrùn, May 22, 1933 - March 19, 1996) was a mathematician from Fuzhou, Fujian, China. He is considered an important figure in China's mathematical history.

His work on the twin prime conjecture and on Goldbach'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.
