Hum Aapke Hain Koun..! (HAHK; English: Who am I to You) is a 1994 Indian musical romantic-comedy film, written and directed by Sooraj R. Barjatya, and produced by Rajshri Productions. Starring Madhuri Dixit and Salman Khan, it celebrates Indian wedding traditions by relating to the story of a married couple and the relationship between their families; a story about sacrificing ones love for ones family. It is an adaptation of the studio's own Bhojpuri film Nadiya Ke Paar (1982).

Earning over ₹1.35 billion (US$20 million) worldwide, the film became the highest-grossing Bollywood film of all time. It contributed to a change in the Indian film industry, with new methods of distribution and a turn towards less violent stories. It was the first Hindi film to gross over ₹1 billion, and when adjusted for inflation, is the highest grossing Hindi film of the 1990s and also still one of the highest-earning Bollywood films ever. Box Office India described it as "the biggest blockbuster of the modern era." The 14-song soundtrack, an unusually large number, is also one of the most popular in Bollywood history, with popular singer Lata Mangeshkar lending her voice for 11 of the 14 songs in the film.

Hum Aapke Hain Koun..! won five Filmfare Awards, including Best Film, Best Director, and Best Actress, as well as winning the National Film Award for Best Popular Film Providing Wholesome Entertainment. It made a lasting impact on wedding celebrations in India, which often include songs and games from the film.
