Sigappu Rojakkal is a 1978 Indian Tamil-language psychological thriller film starring Kamal Haasan and Sridevi in lead roles. Co-written and directed by P. Bharathiraja, it features music by Ilaiyaraaja and cinematography by P. S. Nivas.

In an era of over-dramatised acting in Tamil films, Sigappu Rojakkal was one of the notable exceptions. The film completed a 175-day run at the box office. It won two Filmfare Awards in the Best Actor and Best Director categories.

This film was dubbed in Telugu as Erra Gulabeelu. It was remade in Hindi as Red Rose starring Rajesh Khanna and Poonam Dhillon in lead roles.

The movie was reported to be loosely inspired by Raman Raghav's grisly crimes and Kamal Haasan plays the role of a man named Dileep who is traumatized by women's behavior in his childhood and later a psychopath misogynist who kills women after having sex with them.

The music composed by Ilaiyaraaja. When Haasan was singing an English song at a concert, Ilayaraja who witnessed this observed that he sang the higher notes well, and thus provided him to sing "Ninaivo Oru Paravai". A remixed version of the song was later on M. Rafi's album Aasaiyae Alaipolae.
