Hengqin (simplified Chinese: 横琴岛; traditional Chinese: 橫琴島, Portuguese: Ilha da Montanha) is an island in Zhuhai, a prefecture-level city and special economic zone in Guangdong Province of the People's Republic of China. It has a population of about 3,000. Parts of Hengqin were leased to Macau by the State Council of the People's Republic of China starting in 2009, with the area expanding. In the leased parts of the island, Macau law applies. The whole island is designated a special economic district, as Hengqin New Area, similar to Binhai New Area in Tianjin and Pudong New Area in Shanghai.
