Canning Dock on the River Mersey is part of the Port of Liverpool in northern England.

Having been subsequently enclosed as a wet dock three years earlier,[4] in 1832 it was officially named after the Liverpool MP George Canning.

Canning Dock would have initially served ships involved in the trans-Atlantic slave trade.

By March 2009 work was completed[9][10] on a £22 million extension of the Leeds and Liverpool Canal, providing a further 1.4 mi (2.3 km) of navigable waterway.

[11] The extension includes a small canal basin at Mann Island near Pier Head, and a new lock providing access to Canning Dock.
