Tamasha (transl. Spectacle/Drama) is a 2015 Indian coming-of-age romantic drama film written and directed by Imtiaz Ali and produced by Sajid Nadiadwala from his studio, Nadiadwala Grandson Entertainment. It stars Ranbir Kapoor and Deepika Padukone. The film score and soundtrack album were composed by A. R. Rahman, while the lyrics for the songs were written by Irshad Kamil. Tamasha was filmed in the Indian cities of Shimla, Delhi, Gurgaon, and Kolkata, with additional filming in Tokyo and Corsica. The film tells the story of character Ved Vardhan Sahni (played by Kapoor) in three stages–as a 9-year-old child, a 19-year-old adolescent and a 30-year-old adult in a nonlinear narrative.

Tamasha was released on 27 November 2015 to mixed reviews from film critics, who praised the performances of Kapoor and Padukone, but criticized the complexity of the plot. The film grossed ₹136.63 crore worldwide against its budget of ₹87 crore. Despite being an underwhelming commercial success at the time of its release, the film later gained a strong cult following, especially among the youth.

At the 61st Filmfare Awards, Tamasha received 4 nominations, including Best Actor (Kapoor) and Best Music Director (Rahman), winning Best Lyricist (Kamil for "Agar Tum Saath Ho"). At the 2016 Stardust Awards, the film won Best Actress (Padukone).
