Sigappu Rojakkal (pronounced [siɡappu ɾoːdʑaːkkaɭ] transl. Red Roses) is a 1978 Indian Tamil-language psychological thriller film co-written and directed by Bharathirajaa. The film starring Kamal Haasan and Sridevi, with Goundamani, Bhagyaraj and Vadivukkarasi in supporting roles. It revolves around Dileep, a seemingly humble man who secretly kills women after having sex with them.

Sigappu Rojakkal was inspired by serial killer Raman Raghav's crimes, and another serial killer who was based in Bombay but hailed from Tirunelveli. It was deliberately meant to be different from Bharathiraja's earlier ventures which were set in villages. The dialogues were written by Bhagyaraj, cinematography was handled by P. S. Nivas, and the music was composed by Ilaiyaraaja. Kamal plays an anti-hero in this film.

Sigappu Rojakkal was released on 28 October 1978, three days before Diwali, and completed a 175-day in most of the theatres in Tamil Nadu. It won two Filmfare Awards in the Best Actor and Best Director categories. The film was later remade by Bharathiraja himself in Hindi as Red Rose (1980).
