Avalude Ravukal (transl. Her Nights) is a 1978 Indian Malayalam-language drama film directed by I. V. Sasi and written by A. Sheriff. The film explores the life of Raji (Seema), a teenage prostitute and those of the people around her. Upon its release, the film received less audience during the first three days, but the situation changed in the coming days, and it became one of the year's highest-grossing films. The plot follows a sex worker who has not only been unapologetic about what she does but also considers herself deserving of love and dignity despite her job.

It is considered one of the boldest Malayalam films of all time. At that time, Sasi, an experimental yet highly popular director, tried to highlight a theme which most mainstream directors are afraid to get into. Kamal Haasan and I. V. Sasi made guest appearances in the film. It was dubbed and released in Tamil as Avalin Iravugal and in Hindi as Her Nights, both of which achieved box office success. Additionally, it was remade in Kannada as Kamala (1979) and in Hindi as Patita (1980).
