Changguangxi Wetland Park, National wetland park in Binhu district, Wuxi, China.

Changguangxi Wetland Park is a national wetland park in Binhu District, Wuxi, Jiangsu, China. It lies at the foot of Shitang Bridge on the southwest shore of Lihu, forming a 10-kilometre corridor between Lihu and Taihu. The park covers about 260 hectares, of which roughly 80 hectares is water. Huizhang Hill stands to the west and the Wuxi University Town to the east.

A waterway within the park connecting two lakes has origins tracing back more than 1,700 years to ancient times. This water link demonstrates the region's long history of managing water systems for both practical and environmental purposes.

The name Changguangxi combines the characters for long and broad, describing the 10 km waterway that links Lihu Lake with Taihu Lake. The park is known for birds such as the little egret, the cattle egret and the tree sparrow, which visitors watch along the water.

The park is accessible by multiple bus routes and requires about three hours to explore thoroughly from one end to the other. Well-maintained paths and bridges connect the different wetland sections throughout the site.

The park's waterway was dredged in 245 AD, when Eastern Wu ruler Sun Quan sent official Chen Xun with 30,000 troops to open and clear the Changguangxi channel. The 10 km corridor links Li Lake with Taihu Lake, and the park was listed among China's second batch of national urban wetland parks in May 2005.
