The Chester Canal was a canal linking the south Cheshire town of Nantwich with the River Dee at Chester, providing a route for produce (including salt) from Nantwich to reach Chester and, beyond it, the sea via the Dee estuary.

Today, it is part of the Shropshire Union Canal, and - being instigated by an Act of Parliament in 1777 - it is also the oldest section. Until the building of the later Ellesmere Canal (1805) and the Trent and Mersey Canal it was under-used.
