The Blythe is a river in the English Midlands that runs from Warwickshire, through the borough of Solihull and on to Coleshill. It runs along the Meriden Gap in the Midlands Plateau, is fed by the River Cole and is a tributary of the Tame beside the West Midland Bird Club's Ladywalk reserve. This then joins the Trent, whose waters reach the North Sea via the Humber Estuary. It is one of the cleanest rivers in England..
