Dandong (simplified Chinese: 丹东; traditional Chinese: 丹東; pinyin: Dāndōng), formerly known as Andong, is a coastal prefecture-level city in southeastern Liaoning province, in the northeastern region of People's Republic of China.

It is the largest Chinese border city, facing Sinuiju, North Korea across the Yalu River, which demarcates the Sino-North Korean border. To the southwest of the city, the river flows into Korea Bay. Dandong has therefore had a dynamic history because of its strategic location for the northeast's rich natural resources and because of its convenient access to the ocean. It is designated as a major export production centre for the province, and is a port city connected by rail with Shenyang and Sinuiju. A significant amount of trade with North Korea flows through the city.

The size of the administrative city (prefecture) is 14,981.4 square kilometres (5,784.4 sq mi). As of 2010, the built-up area made of 3 urban districts is 830 square kilometres (320 sq mi) in size and had 865,576 inhabitants. The administrative city contained approximately 2.45 million inhabitants as of the 2010 census.
