Avargal (pronounced [aʋaɾɡaɭ] transl. They) is a 1977 Indian Tamil-language romantic drama film written and directed by K. Balachander. The film stars Sujatha, Kamal Haasan, Rajinikanth and Ravikumar. A triangular love story, it revolves around a woman who is caught between the man she fell in love with and her former sadistic husband who is supposedly reformed and wants to rejoin her.

Avargal was released on 25 February 1977. Although the film was a commercial failure, Sujatha won the Filmfare Award for Best Actress – Tamil, and the film qualified for the Indian Panorama. Balachander later remade the film in Telugu as Idi Katha Kaadu (1979), with Haasan reprising his role.
