Shangchuan Island (Chinese: 上川岛; pinyin: Shàngchuāndǎo) also written (Schangschwan, Sancian, Sanchão, Chang-Chuang or St. John's Island) is the main island of Chuanshan Archipelago on the southern coast of China. Its name originated from São João ("Saint John" in Portuguese). It is part of the Guangdong province, in the South China Sea. Located 14 km from the mainland, it is the largest island in the province. The largest island formerly was the island of Hainan but that was carved out of Guangdong to became a separate province in 1988.
The population of the island is 16,320.
It is known in history for having been the place of death of St. Francis Xavier.
Shangchuan Island was one of the first bases established by the Portuguese off the China coast, during the 16th century. They abandoned this base after the Chinese government gave consent for a permanent and official Portuguese trade base at Macau in 1557.
The island has been isolated from the mainland since the last ice age. It is located near Xiachuan Island, which lies west of Shangchuan. The two islands, together with smaller islet, form Chuanshan Archipelago.
Shangchuan covers the main Shangshuan Island, as well as 12 islets. The total area of the town is 156.7 km². Shangshuan Island has an area of 137.3 km². The island has a 217 km long coastline.
Feisha Beach Resort (飞沙滩旅游区) is a commercial tourist resort located on the island's eastern shore.
