Crouching Tiger, Hidden Dragon (simplified Chinese: 卧虎藏龙; traditional Chinese: 臥虎藏龍; pinyin: Wò hǔ cáng lóng) is a 2000 wuxia film directed by Ang Lee and written by Wang Hui-ling, James Schamus and Kuo Jung Tsai. The film features an international cast of actors of Chinese ethnicity, including Chow Yun-fat, Michelle Yeoh, Zhang Ziyi and Chang Chen. It is based on the Chinese novel of the same name by Wang Dulu, the fourth part of his Crane Iron pentalogy.

A multinational venture, the film was made on a US$17 million budget, and was produced by Asian Union Film & Entertainment, China Film Co-Productions Corporation, Columbia Pictures Film Production Asia, Edko Films, Good Machine International, and Zoom Hunt Productions. With dialogue in Mandarin, subtitled for various markets, Crouching Tiger, Hidden Dragon became a surprise international success, grossing $213.5 million worldwide. It grossed US $128 million in the United States, becoming the highest-grossing foreign-language film produced overseas in American history. The film was the first foreign-language movie (it was filmed in Mandarin Chinese) to break the $100 million (£51 million) mark in USA.

The film premiered at the Cannes Film Festival on May 18, 2000, and was theatrically released in the United States on December 8. An overwhelming critical and commercial success, Crouching Tiger, Hidden Dragon won over 40 awards and was nominated for 10 Academy Awards in 2001, including Best Picture, and won Best Foreign Language Film, Best Art Direction, Best Original Score and Best Cinematography, receiving the most nominations ever for a non-English language film at the time, until 2018's Roma tied this record. The film also won four BAFTAs and two Golden Globe Awards, one for Best Foreign Film. Along with its awards success, Crouching Tiger continues to be hailed as one of the greatest and most influential non-English language films. The film has been praised for its story, direction, cinematography, and martial arts sequences.
