The Shropshire Union Canal, sometimes nicknamed the Shroppie, is a navigable canal in England. The Llangollen and Montgomery canals are the modern names of branches of the Shropshire Union (SU) system and lie partially in Wales.
The canal lies in the counties of Staffordshire, Shropshire and Cheshire in the north-west English Midlands. It links the canal system of the West Midlands, at Wolverhampton, with the River Mersey and Manchester Ship Canal at Ellesmere Port, Cheshire, 66 miles (106 km) distant.
