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 (formally Dongxilian Island) the largest island in Jiangsu Province which lies off its coastline, and Yuntai Mountain (Jiangsu), the highest peak in Jiangsu Province, a few miles from the town center, and the fact that it is a port.
