Fanaa (transl. Annihilation) is a 2006 Indian Hindi-language romantic-thriller film directed by Kunal Kohli and produced by Aditya Chopra and Yash Chopra under the banner of Yash Raj Films. It stars Aamir Khan and Kajol, with supporting performances from Rishi Kapoor, Kirron Kher, Tabu, and Sharat Saxena. Set in Delhi and Kashmir, the narrative follows Zooni, a blind Kashmiri woman who falls in love with her tour guide Rehan, unaware that he is hiding a dangerous secret.

The film marked the first romantic collaboration between Khan and Kajol, who had previously co-starred in Ishq (1997), and marked Kajol's return to cinema after a five-year hiatus following Kabhi Khushi Kabhie Gham... (2001). Fanaa was among the most expensive Hindi films produced at the time and derived its title from the Sufi term meaning "annihilation" or "destruction of the self." Principal photography took place in Delhi and Poland, with cinematography by Ravi K. Chandran and music composed by Jatin–Lalit.

Released theatrically on 26 May 2006, Fanaa received mixed-to-positive reviews from critics, who praised the performances of Khan and Kajol, the cinematography, and the music, while some criticized its tonal shifts and pacing. The film was commercially successful, grossing over ₹1.05 billion (US$13 million) worldwide against a budget of ₹300 million. It was the sixth-highest grossing Hindi film of the year despite being banned in Gujarat due to political controversy surrounding comments made by Khan on the Narmada Dam project.

At the 52nd Filmfare Awards, Fanaa won three awards, including Best Actress for Kajol. Over time, it has been recognized for its contribution to the genre-blending of romance and political thriller in mainstream Hindi cinema.
