The Forbidden Kingdom (Chinese: 功夫之王: Gong Fu Zhi Wang (Mandarin) or Gung Fu Ji Wong (Cantonese) and translated King of Kung Fu (English); Working title: The J & J Project) is a 2008 Chinese-American fantasy wuxia film written by John Fusco and directed by Rob Minkoff, starring Jackie Chan, Jet Li, Michael Angarano, Liu Yifei, Collin Chou, and Li Bingbing. Loosely based on the 16th-century Chinese novel Journey to the West, the plot revolves around Jason Tripitikas (Angarano), a modern-day American teenager who is transported back to ancient China after discovering the Monkey King's magical staff. He accompanies Lu Yan / Old Hop (Chan) and Sun Wukong / Silent Monk (Li) on their quest to return the staff to its rightful owner while trying to avoid the minions of the evil Jade Emperor (Chou). The action sequences were choreographed by Yuen Woo-ping.

The film is regarded as the first coproduction helmed by an American director to make a primarily English-language wuxia genre film set in a pre-modern China for a global audience. Heavily promoted as the first film starring both Chan and Li, it was distributed in the United States through Lionsgate and The Weinstein Company, and through The Huayi Brothers Film & Taihe Investment Company in China. It was released on DVD and Blu-ray in the US and Hong Kong on September 9, 2008 and the United Kingdom on November 17, 2008. Rotten Tomatoes' critical consensus praises the fight scenes but says the film has too much filler. The Forbidden Kingdom grossed $128 million against a budget of $55 million.
