Nanyang (Chinese: 南洋; pinyin: nányáng) is the Chinese name for the geographical region south of China, particularly Southeast Asia. Literally meaning "Southern Ocean", it came into common usage in self-reference to the large ethnic Chinese migrant population in Southeast Asia, to be more precise, in Singapore, the Philippines, Malaysia, Thailand, Indonesia, and Vietnam.
Nanyang is contrasted with Xiyang (Western Ocean), which refers to the Western world, and Dongyang (Eastern Ocean), which refers to Japan.
