Lianyungang (simplified Chinese: 连云港; traditional Chinese: 連雲港; pinyin: Liányúngǎng) is a prefecture-level city in northeastern Jiangsu province, China. It borders Yancheng to its southeast, Huai'an and Suqian to its south, Xuzhou to its southwest, and the province of Shandong to its north. Its name derives from Lian Island, the largest island in Jiangsu which lies off its coastline, and Yuntai Mountain, the highest peak in Jiangsu, a few miles from the city center, and the fact that it is a port. The name can be literally translated as the Port Connecting the Clouds. Lianyungang was home to 4.65 million inhabitants as of the 2020 census whom 1,210,767 lived in the built-up (or metro) area made of Haizhou and Lianyun counties. Lianyungang was known in the West as Haichow (Postal romanization), which means the City of Sea. Haichow was opened to foreign trade by the Qing imperial government in 1905.
