Hard Boiled (traditional Chinese: 辣手神探; pinyin: Làshǒu shéntàn) is a 1992 Hong Kong action film directed by John Woo. The film stars Chow Yun-fat as Inspector "Tequila" Yuen, Tony Leung Chiu-Wai as Tony, an undercover cop, and Anthony Wong as Johnny Wong, a leader of criminal triads. The film features Tequila, whose partner (Bowie Lam) is killed in a tea house gunfight with a small army of gangsters. One of the mob's high-ranking assassins is the undercover cop Tony, who must team up with Tequila for their common pursuit of taking down Wong's crime syndicate. The film leads up to a climax in a hospital, where the two must rescue innocent civilians and newborn babies from the maternity ward while fighting off dozens of mob hitmen.

Hard Boiled is John Woo's last Hong Kong film to date. After making films that featured gangsters in the lead role, Woo wanted to make a Dirty Harry styled film to glamorize the role of a police officer. After the death of screenwriter Barry Wong, the script of the film went through many changes while still filming. New characters such as Mad Dog and Mr. Woo were introduced while the original idea of a baby poisoning psychopath were cut from the script.

The film was released in Hong Kong in 1992 to generally positive audience reception, but it was not as popular as Woo's previous action films, such as A Better Tomorrow and The Killer. Reception from western critics was much more positive, with many critics proclaiming its action scenes to be some of the best ever filmed. In 2007, a video game sequel to Hard Boiled titled Stranglehold was released, which is in the process of being made into a film.
