Arunagirinathar (pronounced [aɾ̪uɳaɡiɾ̪in̪aːt̪aɾ̪]) is a 1964 Indian Tamil-language biographical film, directed by T. R. Ramanna and written by Sakthi T. K. Krishnasamy.

Based on the poet of the same name, the film stars T. M. Soundararajan, supported by M. R. Radha, B. S. Saroja, Sarada, C. Lakshmi Rajyam and Master Raghunath.

Arunagiri is portrayed as attracted to the pleasures of the flesh and spent his youth pursuing a life of debauchery.

Eventually Aadhilakshmi is unable to meet his demands for money to support his depraved life.

To prevent Arunagiri from killing himself, his sister says that he should sell her in order to have money for prostitutes.

Arunagiri feels guilty and attempts suicide by jumping off a temple tower, but Murugan himself, disguised as a pious young man, saves him.
