Sathi Leelavathi (transl. Leelavathi, the chaste wife) is a 1995 Indian Tamil-language comedy film directed, co-written, photographed and edited by Balu Mahendra. The film stars Ramesh Aravind, Kalpana and Heera, with Kovai Sarala and Kamal Haasan in supporting roles. It revolves around Arun (Aravind) who, unhappy with his wife Leelavathi's (Kalpana) plain looks and weight, engages in an extramarital affair with Priya (Heera).

The film was produced by Haasan, with the story by Ananthu adapted loosely from the 1989 American film She-Devil and dialogues by Crazy Mohan. Ilaiyaraaja served as the music composer. Sathi Leelavathi was released on 15 January 1995 and became a commercial success. It was remade in Hindi as Biwi No.1 (1999) and in Kannada as Rama Shama Bhama (2005) with Aravind and Haasan reprising their roles.
