Magical Smile) is a 1986 Indian Tamil-language film directed by V. Thamizhazhagan in his debut; he co-produced with G. Thyagarajan.

The film stars Sathyaraj and Nadhiya, with Raghuvaran, Baby Sujitha, Thengai Srinivasan, Senthil, Jai Jagadish, Bob Christo and V. S. Raghavan in supporting roles.

Sathyaraj comes across a mute child abandoned by her mother and starts bringing her up to be a police officer.

She starts investigating Sathyaraj’s criminal activities and how she handles the scene makes the story interesting.
