Hero (Chinese: 英雄; pinyin: Yīng Xióng) is a Chinese martial arts, drama and adventure film of the wuxia genre, directed by Zhang Yimou with music by Tan Dun. Starring Jet Li as the nameless protagonist, the movie is loosely based on the legendary Jing Ke.

A group of assassins: Flying Snow (飛雪) (Maggie Cheung), Broken Sword (殘劍) (Tony Leung Chiu Wai), and Long Sky (長空) (Donnie Yen), have sworn to kill the King of Qin (秦王) (Chen Daoming), and Nameless (無名) (Jet Li) comes to the royal capital to claim the reward offered for their defeat. The movie tells the story of his conversation with the King of Qin, and the flashbacks depicted the journey he took to earn the honor of sitting before the emperor. Zhang Ziyi stars as Broken Sword's servant Moon (如月).

Hero was first released in China on October 24, 2002; it was both the most expensive and the highest-grossing motion picture in Chinese cinema history. Miramax owned the American-market distribution rights, but delayed the release of the film for nearly two years. It was finally presented by Quentin Tarantino to American theaters in August 27, 2004.
