Unnai Charanadaindhen is a 2003 Indian Tamil-language romantic drama film directed by Samuthirakani, starring Venkat Prabhu, S. P. B. Charan and Meera Vasudevan. Samuthirakani's directorial debut, it was produced by Charan's Capital Film Works and features a soundtrack composed by S. P. Balasubrahmanyam. Although the film was made on a small budget and fetched critical acclaim upon release, also winning two Tamil Nadu State Film Awards, Charan has said that it was not a profitable venture. Samuthirakani later directed the Telugu remake Naalo (2004).
