The Battle of Dachen Archipelago (simplified Chinese: 大陈等岛之战; traditional Chinese: 大陳等島之戰; pinyin: Dàchén Děng Dǎo Zhī Zhàn) was a struggle between the Nationalists and the Communists for the control of several archipelagos just off the coast of Zhejiang, China during the Chinese Civil War in the post-World War II era, and it was part of the First Taiwan Strait Crisis. The Communists targeted and eventually took the Dachen Archipelago, and the other two smaller archipelagos from Nationalists: the Southern Muntjac Archipelago (simplified Chinese: 南麂山列岛; traditional Chinese: 南麂山列島; pinyin: Nán Jǐshān Liè Dǎo) and the Southern Deer Mountain Archipelago (simplified Chinese: 南鹿山列岛; traditional Chinese: 南鹿山列島; pinyin: Nán Lùshān Liè Dǎo).
