The Wanshan Archipelago, formerly known as the Ladrones Islands, is a 104-island archipelago that is a part of Xiangzhou District in Zhuhai, Guangdong Province, China.

Most of the islands of the archipelago are in the Wanshan Marine Development Experimental Zone [Wikidata] (万山海洋开发试验区) which consist of three towns: Guishan Town (桂山镇), Dangan Town (担杆镇) and Wanshan Town (万山镇).

Before Chu-Hai County [zh-cn] was created in 1953, the islands were part of Po-On County.

The islands are situated in the South China Sea, to the south of the opening of the Pearl River estuary and Hong Kong.

The archipelago includes several groups of islands. The western group, located south of the Pearl River estuary and Lantau Island, was formerly known to Europeans as the Ladrones, from the Spanish for "thieves". It comprises Greater Wanshan, Guishan, and Wai Dangling Islands and the Zhizhou, Sanmen, and Aizhou groups. The eastern group, located south of Hong Kong Island, was known as the Lema Islands. Today, they are known as the Jiapeng Liedao and Dangan Liedao, respectively.

The largest island, Dangan, features mountainous terrain similar to Hong Kong.

It has been suggested that this section be split out into another article titled Gap Rock. (Discuss) (June 2022)

• Wenwei Zhou (蚊尾洲; 'Mosquito Tail Island', also Gap Rock in English), 0.022 km. The small island is in the form of two hillocks, about 24 to 30 m (80 to 100 ft) high, and the island derives its English name from the gap between them. The Gap Rock Lighthouse [zh] (蚊尾洲燈塔) on the island was built to serve as a navigation aid to vessels sailing to Hong Kong. It was built by a Hong Kong contractor and partly funded by the Imperial Qing Government for both construction and maintenance costs. Besides the lighthouse it had separate European and Chinese living quarters, telegraph and storage rooms. It came into operation in 1892 under Hong Kong control (island still under Chinese sovereignty) staffed by British lighthouse keeper and Chinese assistants. The lighthouse lenses and windows were damaged by typhoons in 1893 and 1905, the keepers eventually abandoned the site, civil war in China left it in ruins by the 1930s and 1940s. Taken over in 1949 by the Communists in Beijing, lighthouse was restored in 1986 with solar panels and fully automated. A small helipad was added in by the Chinese.
