Ardharathiri (Midnight) is a 1969 Indian Telugu-language thriller film written by Aarudhra and directed by P. Sambasiva Rao in his debut.

Inspired by the Charlotte Brontë novel Jane Eyre, the film stars Jaggayya and Bharathi.

Adapted from The Hindu:[1] P. Sambasiva Rao's desire to direct a thriller film arose after he read the Charlotte Brontë novel Jane Eyre.

As Sambasiva Rao put it, "In evolving the characters of Prasad and Keshav, traces of influence can be found in Emily Brontë's Wuthering Heights".

The film marked his directorial debut and was produced by P. Gangadara Rao under Hyderabad Movies.
