The Eastern Zhejiang or Zhedong Canal, also known as the Hangzhou–Ningbo or Hangyong Canal, is a major canal connecting Hangzhou, Shaoxing, and Ningbo in northern Zhejiang, China. It runs 239 kilometres (149 mi), connecting the Qiantang, Cao'e, and Yong watersheds with Hangzhou's terminus for the Grand Canal and Ningbo's ports on the East China Sea. Since 2013, it has been officially considered the southernmost section of the Grand Canal itself.
The terrain of this area of Zhejiang slopes down from mountains to the south to the coastal plain along Hangzhou Bay to the north. The oldest section of the present waterway was the Shanyin Canal constructed in Shaoxing by the Yue official Fan Li in the 5th century BC during the late Spring and Autumn period. Despite the need to create numerous locks and dams to allow boats to change levels at the various rivers crossed by the canal, the entire route was completed with the excavation of the Xixing Canal under the Jin official He Xun in the 3rd century AD.
