High and Low (Japanese: 天国と地獄, Hepburn: Tengoku to Jigoku, lit. 'Heaven and Hell') is a 1963 Japanese police procedural crime film directed and edited by Akira Kurosawa. It was written by Kurosawa, Hideo Oguni, Eijiro Hisaita, and Ryūzō Kikushima as a loose adaptation of the 1959 novel King's Ransom by Evan Hunter. Starring Toshiro Mifune, Tatsuya Nakadai, Kyōko Kagawa, Tatsuya Mihashi, Yutaka Sada, and Tsutomu Yamazaki, it tells the story of Japanese businessman Kingo Gondo (Mifune) struggling for control of the major shoe company at which he is a board member. He plans a leveraged buyout of the company with his life savings, when kidnappers led by Ginjirô Takeuchi (Yamazaki) mistakenly kidnap his chauffer's son to ransom him for 30 million yen.

Production began in 1962 at Toho Studios. Shot mostly on location at Yokohama, and on set at Toho, filming lasted from 2 September to 30 January 1963. The film has been regarded as embodying the post-World War II Japanese economic miracle prior to the 1964 Summer Olympics in Tokyo, particularly in its highlighted use of the Kodama express train. The film's complex approach to issues of social class and narrative structure have been critically analysed as substantial adaptational accomplishments. Post-production took just under a month, and after positive test-screenings in mid-February 1963, it received a wide distribution.

Released in Japan on 1 March 1963, High and Low received generally positive reviews domestically and abroad. With a budget of ¥230 million, it was the largest budget Kurosawa had worked with at the time, and became the highest-grossing film at the Japanese domestic box office that year. It was nominated for the Golden Lion at the Venice Film Festival and Best Foreign Film at the Golden Globe Awards for 1964. The film has since received greater acclaim, and is considered by some to be equal to Kurosawa's films Rashomon (1950) and Seven Samurai (1954). It is viewed as influential on police procedurals, and has been remade multiple times internationally.
