The River Tweed, or Tweed Water (Scottish Gaelic: Abhainn Thuaidh, Scots: Watter o Tweid, Welsh: Tuedd), is a river 97 miles (156 km) long that flows east across the Border region in Scotland and northern England. Tweed cloth derives its name from its association with the River Tweed. The Tweed is one of the great salmon rivers of Britain and the only river in England where an Environment Agency rod licence is not required for angling. The river generates a large income for the local borders region, attracting anglers from all around the world, acting as one of the best salmon rivers in Scotland.Tweed is an Old Brythonic (Celtic) name meaning "border".
It rises in the Lowther Hills at Tweed's Well near to where the Clyde, draining northwest (10 kilometres (6.2 mi) from the Tweed's Well), and the Annan draining south (1.9 kilometres (1.2 mi) from the Tweed's Well) also rise. "Annan, Tweed and Clyde rise oot the ae hillside" is a saying from the Border region. East of Kelso, it becomes a section of the eastern part of the border. Entering England, its lower reaches are in Northumberland, where it enters the North Sea at Berwick-upon-Tweed.
The river's valley floor is a drumlin field. It is the relic of a paleo-ice stream that flowed through the area during the last glaciation. Major towns through which the Tweed flows include Innerleithen, Peebles, Galashiels, Melrose, Kelso, Coldstream and Berwick-upon-Tweed, where it flows into the North Sea. Tweed tributaries include:
The upper parts of the catchment of the Tweed in Scotland form the area known as Tweeddale, part of which is protected as the Upper Tweeddale National Scenic Area, one of 40 such areas in Scotland which are defined so as to identify areas of exceptional scenery and to ensure its protection from inappropriate development.
