Kalyanaraman is a 1979 Indian Tamil-language supernatural comedy film directed by G. N. Rangarajan and written by Panchu Arunachalam. The film stars Kamal Haasan and Sridevi, while V. K. Ramasamy, Major Sundarrajan, Thengai Srinivasan, V. S. Raghavan, Senthamarai, Pushpalatha, Manorama and Master Japan Kuppu play supporting roles. It revolves around Kalyanam, a tea estate owner's son who is duped and murdered by a gang trying to seize the property. Kalyanam lives on as a ghost, his twin brother Raman learns the truth and returns for revenge.

Arunachalam initially wanted to make a film starring Haasan and Rajinikanth, and had the actors' dates ready. The actors did not want to appear in a film together, so it was decided to produce one film for each actor; the film starring Haasan became Kalyanaraman. The film is Rangarajan's directorial debut, and was produced by Arunachalam's wife Meena under their banner P. A. Art Productions; it was photographed by N. K. Viswanathan and edited by K. R. Ramalingam. The story was inspired by Idhu Nijama (1948) and Dona Flor and Her Two Husbands (1976).

Kalyanaraman was released on 6 July 1979 and became a commercial success, running in theatres for 140 days. It was remade in Hindi as Ghazab (1982) and in Kannada as Sriramachandra (1992). Six years after the release of Kalyanaraman, a sequel titled Japanil Kalyanaraman was made.
