Thirudiya Idhayathai is a 2005 Indian Tamil-language romantic action film written and directed by Murali Krishna.
The film stars Rohan Salian, Kunal, and Shubha Poonja in lead roles. The score and soundtrack for the film were composed by Bharani.
The title of the film is based on a song from Paarvai Ondre Pothume, also starring Kunal. Kunal was cast alongside Rohan Salian, marking his third collaboration with Murali Krishna after Paarvai Ondre Podhume (2001) and Pesadha Kannum Pesume (2002).
Rohan Salian, who had been best known for being the boyfriend of actress Sherin in the early 2000s, announced that he would produce and act in the film. Shubha Poonja worked on the film alongside her commitments for Machi (2004) opposite Dushyanth and the unreleased Shanmugha opposite Richard.
