Dil Se.. (lit. 'From the Heart..') is a 1998 Indian Hindi-language romantic thriller film written and directed by Mani Ratnam who produced it with Ram Gopal Varma and Shekhar Kapur. Set against the backdrop of Insurgency in Assam, the film stars Shah Rukh Khan and Manisha Koirala, while Preity Zinta makes her film debut in a supporting role. An example of parallel cinema, it is noted as the final installment in Ratnam's trilogy consisting of Roja (1992) and Bombay (1995). The film's soundtrack album, composed by A. R. Rahman, sold six million units in India.

Noted for its aspects of nonlinear storytelling, the film was moderately successful at the domestic box office; however, it was a major success overseas, earning $975,000 in the United States and £537,930 in the United Kingdom, becoming the first Indian film to enter the top 10 in the United Kingdom box office charts, and it was also a hit in Japan.
