Mann (transl. The Psyche) is a 1999 Indian Hindi-language romantic drama film written and directed by Indra Kumar. The film starred Aamir Khan and Manisha Koirala, pairing them for the second time, and also features Anil Kapoor, Sharmila Tagore and Neeraj Vora with Rani Mukerji in a special appearance. This is the second collaboration between Khan and Koirala since Akele Hum Akele Tum (1995). The film is mainly based on the 1957 American film An Affair To Remember. Mann received positive reviews upon release, but became a box office failure. Aamir Khan has admitted that he became dissatisfied with the film within a few days of shooting but completed it due to his commitment to Indra Kumar.

The soundtrack by Sanjeev–Darshan has been surrounded by music plagiarism controversies.
