Gajini is a 2005 Indian Tamil romantic psychological thriller film directed by A. R. Murugadoss and produced by Salem Chandrasekharan under Sri Saravanaa Creations. This movie was a remake of English film called memento.

The film stars Suriya, Asin, Nayantara in lead roles with Pradeep Rawat and Riyaz Khan playing supporting roles. Harris Jayaraj composed the soundtrack and background music, while R. D. Rajasekhar and Antony were the film's cinematographer and editor respectively. The film explores the life of a rich businessman who develops anterograde amnesia following a violent encounter in which his love interest was killed. He tries to avenge the killing with the aid of Polaroid Instant camera photographs, permanent tattoos on his body and a medical college student.

The film was initially titled Mirattal with Ajith intended to play the lead role, but the project was shelved. Murugadoss retitled the production Ghajini and cast the new leads. The revived project was announced in February 2005. Production began shortly afterwards in April and was completed by March on the same year. The film was shot at Chennai, while two song sequences were filmed in Switzerland.

It was dubbed and released in Telugu by Allu Aravind in November 2005, and both versions enjoyed critical and commercial acclaim. The film was released on 29 September 2005 and received positive reviews from critics with praise directed towards the performances of lead pair and the film's plot. It was remade into a Hindi film by Murugadoss again in 2008, starring Aamir Khan with Asin reprising her role.

Chitra (Nayantara), a medical student and her friends are working on a project about the human brain. She wants to investigate the curious case of Sanjay Ramaswamy (Suriya), a (former) notable Chennai based businessman, who is reported to have anterograde amnesia. Her professor denies access to Sanjay's records as it is currently under criminal investigation. Chitra, nonetheless, decides to investigate the matter herself.
