Kabhi Khushi Kabhie Gham (Devanagari: कभी ख़ुशी कभी ग़म, Nastaliq: کبھی خوشی کبھی غم - "Sometimes Happiness, Sometimes Sadness") is a Bollywood film released in India and countries with large NRI populations on December 14, 2001.

It features Amitabh Bachchan, Jaya Bachchan, Shahrukh Khan, Kajol, Hrithik Roshan, Kareena Kapoor and Rani Mukerji in a guest appearance. It is director Karan Johar's second movie (after Kuch Kuch Hota Hai).

Kabhi Khushi Kabhie Gham was the highest grossing Indian film overseas till 2006, when its record was broken by Kabhi Alvida Naa Kehna. It climbed up to 3rd place in the British box office within two weeks of release, and maintained its place for over 3 weeks. The film was also thought to have broken the American Box Office Top 10, but this remains uncertain due to a lack of confirmed figures from the distributors. The film was the first Bollywood feature to see a theatrical release in Germany (with German subtitles, a dubbed version was produced, too). It was the highest grossing Indian film ever until Sanjay Leela Bhansali's Devdas (2002) released.
