Eugenie de Sade (original titles: Eugénie and Eugenie Sex Happening) is a softcore film adaptation and modern-day update of the Marquis de Sade's short story "Eugénie de Franval" (1800) directed by Spanish filmmaker Jesús Franco in 1970 and released in 1973. It has often been confused with his earlier Eugenie… The Story of Her Journey into Perversion (1970), an adaptation of de Sade's book Philosophy in the Bedroom (1795), as both films are often referred to simply as Eugenie.
