De mulieribus claris (English: On Famous Women) is a collection of biographies of historical and mythological women by the Florentine author Giovanni Boccaccio, first published in 1374. It is notable as the first collection devoted exclusively to biographies of women in Western literature. At the same time as he was writing On Famous Women, Boccaccio also compiled a collection of biographies of famous men,  De Casibus Virorum Illustrium (On the Fates of Famous Men).
