Charles Dufraisse (20 August 1885, in Excideuil – 5 August 1969, in Excideuil) was a French chemist. With Charles Moureu, he conducted pioneer research of autoxidation and antioxidants.

In 1921 he received his doctorate at Paris with the thesis Contribution à l'étude de la stéréoisomérie éthylénique, and served as an associate director in the laboratory of organic chemistry at the Collège de France. In 1927 he was named a professor at the École supérieure de physique et de chimie industrielles de la Ville de Paris, and in 1942 became a professor at the Collège de France. He was cofounder of the Institut français du caoutchouc (French Institute of Rubber).[http://cths.fr/an/prosopo.php?id=112117 DUFRAISSE Charles Robert] Sociétés savantes de France
