Jinguashi (Chinkuashih; Chinese: 金瓜石; pinyin: Jīnguāshí; Wade–Giles: Chin1-kua1-shih2; Pe̍h-ōe-jī: Kim-koe-chio̍h) is a town in Ruifang District, New Taipei City, Taiwan, notable for its historic gold and copper mines. It is also known as Kinkaseki in Japanese and was under Taihoku Prefecture during Japanese rule. From 1942–1945, during the final years of World War II, it was used by the Japanese as a prisoner-of-war camp.
Although the minerals have since been depleted, the town still attracts many visitors to its Gold Ecological Park, which opened in October 2004. Jinguashi was named a potential World Heritage site in 2002.
