Kaala Patthar (transl. Black Stone) is a 1979 Indian Hindi-language action drama film produced and directed by Yash Chopra, with a screenplay written by Salim–Javed. The film was based on the Chasnala mining disaster, and is the fourth collaboration between Amitabh Bachchan, Shashi Kapoor and director Yash Chopra, which succeeded the films Deewaar (1975), Kabhie Kabhie (1976) and Trishul (1978).

In spite of the film only doing average business at the box office,[2] the film was critically acclaimed, and received several Filmfare Award nominations.[3] It attained cult status, and is considered a classic in Hindi cinema. Amitabh Bachchan was much appreciated for his portrayal of ex-Navy captain now working in mines, in order to forget his past.
