Punnami Naagu () is a 2009 Indian Telugu-language female-centric horror film directed by A. Kodandarami Reddy. Mumaith Khan plays dual roles as a snakewoman and a model (city woman). The film was remade in Tamil as Pournami Nagam (2010).
Mumaith Khan plays a snake woman who believes in love and not revenge, and the people from the village think that her character is a devadasi. A childhood scene regarding Mumaith Khan's character was shot in Tamil Nadu.
The music is composed by S. A. Rajkumar. The film features a remix of "Ragulutondi" from Khaidi (1983) and also reuses archival footage from the said film.
Jeevi of Idlebrain.com gave the film a rating of one-and-a-half out of five and wrote that "[i]t is for the people who still want to see bhakti cinemas made on snakes". A critic from Bangalore Mirror wrote that "The story itself is pretty old-fashioned and sans logic".
