Chen Jingrun (1933-96) was a Chinese mathematician who made significant contributions to number theory.

Chen was born in Fuzhou, East China's Fujian province. He graduated from the Mathematics Department of Xiamen University in 1953 and served at his alma mater as a teaching assistant since 1955. In 1957, he was recommended by Hua Luogeng, a famous Chinese mathematician, and transferred from the Mathematics Department of Xiamen University to the Institute of Mathematics, Chinese Academy of Sciences.

In 1981, Chen was elected academician of the Chinese Academy of Sciences. He was also a member of the mathematics group of the State Scientific and Technological Commission, and chief editor of the journals, Acta Mathematica Sinica and Chinese Quarterly Journal of Mathematics.

Chen published more than 50 academic papers and four books. His work on many challenges, such as Waring's problem and the Goldbach conjecture, led to progress in analytic number theory. He achieved a good many honors during his lifetime, including the National Science Conference Award and the first prize in the China's State Natural Science Award.

Chen was also a member of the fourth, fifth and sixth National People's Congresses.
