The Lingqu Canal (灵渠 Líng qú) is located in Xing'an County, near Guilin, in Guangxi Province, China.

In 214 BC, Qin Shi Huang, the First Emperor of the Qin Dynasty (221-206 B.C.), ordered the construction of a canal connecting the Xiang and Lijiang rivers to attack the nearby southern country Bai Yue. It is one of the three big water conservation projects of ancient China and is the oldest contour canal in the world. Its length reaches 36.4 km and was installed with thirty-six canal lock gates. The architect who designed the canal was Shi Lu (fl. late 3rd century BC).

The canal has been placed on the UNESCO World Heritage Sites Tentative List.
