Nanxun (simplified Chinese: 南浔镇; traditional Chinese: 南潯鎮; pinyin: Nánxún Zhèn) is a historic town in Nanxun District of Huzhou, Zhejiang, China. As of the 2007 census it had a population of 119,300 and an area of 141-square-kilometre (54 sq mi).

The name of Nanxun was coined by a combination of the initial Chinese characters of two place' names in the region: "Nanlin" (Chinese: 南林; lit. 'Southern Wood') and "Xunxi" (Chinese: 浔溪; lit. 'Xun Stream').

Established in 1252 in the Southern Song dynasty (1127–1279), Nanxun is located in the northeast of Huzhou city. It was one of the richest towns in Jiangnan from mid-Ming down to mid-Qing dynasties. During this period, with the development of silk industry and rise of commodity economy, it experienced unprecedented prosperity, and developed into the center of China's silk trade at the beginning of 20th century. It became the most prosperous town in Jiangnan region, producing hundreds of magnates. As a popular saying went, "What counts as a city in Huzhou is barely half the size of Nanxun." (湖州一个城，不及南浔半个镇)

The introduction of Christianity into the Nanxun area began in 1860, belonging to the American Methodist Episcopal Mission. The Nanxun Christian Church is a Protestant church in the town. It was built in 1927.

The Guanghui Palace is a Taoist temple in the town. It was first established in the Northern Song dynasty (960–1127) and was destroyed and rebuilt many times. The present version was completed in 2003.
