La flor de Irupé ("The Irupé Flower"), also known as La flor desnuda ("The Naked Flower") and Love Hunger, is a 1962 black-and-white Argentine erotic crime drama film directed by Alberto Dubois and starring Libertad Leblanc, Luis Alarcón and Héctor Pellegrini. The title is inspired by a Guarani legend about the maiden associated with the Irupé flower. This was Leblanc's first leading role, and the film helped her to achieve international stardom. It was originally released in Argentina's cinemas on October 4, 1962.

La flor de Irupé gained attention for its daring inclusion of nudity, unusual for its time, and the undeniable physical allure of the lead character. This bold approach contributed to its success at the box office, propelling 24-year-old Libertad Leblanc to become a prominent sex symbol of the era, particularly in Argentina and Mexico.
