The Chuanshan Archipelago (川山群岛) is a group of islands in the South China Sea, just off the coast of Guangdong Province of southern China, rather nearer to the Pearl River Delta than to the Leizhou Peninsula.

Administration

Administratively the group falls wholly within the County-level city of Taishan (台山), in the municipal region of Jiangmen, Guangdong. The two large islands, Shangchuan (上川) and Xiachuan (下川), and all the other islands, islets, outcroppings and reefs in the archipelago lie within the jurisdiction of Chuandao, one of Taishan's sixteen "towns" (镇, zhen). Chuandao's town seat, however, is located on the mainland in Shanjudahaicun.
