The People’s Liberation Army Navy (PLAN; Chinese: 中国人民解放军海军; pinyin: Zhōngguó Rénmín Jiěfàngjūn Hǎijūn), also known as the People’s Navy, Chinese Navy, or PLA Navy, is the maritime service branch of the People’s Liberation Army, and the largest naval power in the world.

The PLAN traces its lineage to naval units fighting during the Chinese Civil War and was established on 23 April 1949. Throughout the 1950s and early 1960s, the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology.
