Chemistry is a 2009 Indian Malayalam-language horror film directed by Viji Thampi and written by Vinu Kiriyath.

The film stars Saranya Mohan, Shilpa Bala, Mukesh and Vineeth, while Manoj K. Jayan, Rajesh Hebbar, Jagathi Sreekumar, and Siddique play supporting roles.

The story takes place at Mount Academy School, where three girls - Gowri (Shilpa Bala), Kalyani (Drishya) and Alina (Krishna Vijay) - were found dead possibly due to suicide.

After some days, Gowri's vengeful spirit appears in front of Parvathy, to help her take revenge on the people who killed her.

All this was interrupted when Aloshy (Vineeth), the dance teacher of the three dead girls, takes naked pictures of them through hidden cameras.
