Iruvar (transl. The Duo) is a 1997 Indian Tamil-language epic political drama film co-written, produced, and directed by Mani Ratnam. The film, inspired by the lives of M. G. Ramachandran, M. Karunanidhi and J. Jayalalithaa, is set against the backdrop of cinema and politics in Tamil Nadu. It stars an ensemble cast including Mohanlal, Prakash Raj, Aishwarya Rai, Revathi, Gautami, Tabu, and Nassar. Rai, who was crowned Miss World 1994, made her first screen appearance, playing dual characters.

The high-budget film had its original soundtrack composed by A. R. Rahman, and the cinematography was by Santosh Sivan. This film marked Mohanlal's debut in Tamil cinema after having only a cameo in Gopura Vasalile.
