Jean Foyer (21 April 1921, Contigné, Maine-et-Loire – 3 October 2008, Paris) was a French politician and minister.

Between 1962 and 1967, he was Minister of Justice, during this time he directed several important legal reforms on several subjects (family, ownership and business, nationality, etc.).

Jean Foyer was known to be an outspoken defender of a very traditional conception of society and sexual morality, and in 1981, he led a fierce fight against the repeal of Article 331(2) of the Penal Code, an article inherited from the Vichy regime which maintained the age of consent for homosexual relations at eighteen years old (whereas it was fifteen years old for heterosexual relations).

During the debate on 20 December 1981, he feared that the repeal of this law would favor the "lecherous old man who sodomizes a fifteen-year-old boy".

He also asked: "Is the famous freedom that is being expoused just the right of the ogre to devour the little child?".
