Jacques Ruffié (22 November 1921, Limoux, France – 1 July 2004) was a French haematologist, geneticist, and anthropologist. He founded a discipline, called blood typing, which allowed the study of blood characteristics to find the history of the people, their migration and their successive interbreeding. He was a colleague and great personal friend of Michel Foucault at the College de France; Foucault mentions him in a newly discovered essay review of a book that Ruffié published in 1976, entitled ''De la biologie à la culture'' (''From Biology To Culture'').
