Dongguan (Chinese: 东莞; pinyin: Dōngguǎn) is a prefecture-level city in central Guangdong province, People's Republic of China.

An important industrial city located in the Pearl River Delta, Dongguan borders the provincial capital of Guangzhou to the north, Huizhou to the northeast, Shenzhen to the south, and the Pearl River to the west.

It is also home to the world's largest, though mostly empty, shopping mall, New South China Mall. City administration is considered especially progressive in seeking foreign direct investment. The three neighboring municipalities of Guangzhou, Dongguan, and Shenzhen are home to over 25 million residents, accounting for a large proportion of the Pearl River Delta Region's population.

Dongguan ranks behind only Shenzhen, Shanghai and Suzhou in exports among Chinese cities, with $65.54bn in shipment.
