Haiyong () is a town of Haimen District in Nantong, Jiangsu, China. Together with neighboring Qilong, it forms a pene-enclave of the province on Chongming Island, most of which belongs to the province-level municipality of Shanghai. Haiyong presently covers about and had a population of 5,004 during the year 2000 census.
Location Haiyong is a pene-enclave bordered on the south and west by Shanghai's Chongming County, on the east by Qidong's Qilong Township, and on the north by the Yangtze. Because of its unusual position, it is sometimes described in Chinese as "Shanghai in Jiangsu" or "Haimen on Chongming". It is located about from downtown Shanghai and from Shanghai's Pudong International Airport.
History Yonglongsha, a shoal in the channel of the Yangtze north of Chongming Island, reappeared most recently in 1937. Workers from Haimen began to utilize the land in 1966 and, by 1968, had stabilized the land enough that the conflicting claims of Haimen and Qidong were mediated by Nantong, which divided the island between them. Over 3000 workers labored over the next year, reclaiming by 1970. The area was then incorporated into Haimen in 1972 as the Yonglongsha Farm. Continuing reclamation projects and natural deposition of sediment joined it to Chongming Island in 1975. The present township was established in 1992. It was connected to Chongming's road network but this was only connected to Jiangsu by ferry service prior to the 2011 opening of the Chongqi Bridge between Chenjia and Qidong. Its area was recently increased by the addition of another of reclaimed land.
Prior to Yonglongsha's absorption by Chongming, it offered ferry service to Haimen's Lingdian Harbor (t , s , p Língdiāngǎng) and Qidong's Sanhe Harbor (, Sānhégǎng).Office of Shanghai Chronicles.

Haiyong Township was changed to Haiyong Town in September 2015.
