River in the Scottish Borders and northern England
other rivers with this name

The River Tweed, or Tweed Water, , Tuedd), is a river 97 mile (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.

Tweed may represent an Old Brittonic name meaning "border". A doubtful proposal is that the name is derived from a non Celtic form of the Indo European root *teuha meaning "swell, grow powerful".

The River Tweed flows primarily through the scenic Borders region of Scotland. Eastwards from the settlements on opposing banks of Birgham and Carham it forms the historic boundary between Scotland and England. It rises in the Lowther Hills at Tweed's Well near to where the Clyde, draining northwest ( from the Tweed's Well), and the Annan draining south ( 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.

Despite that the catchment straddles the border between Scotland and England, management of it – in terms of water quality, bio security, and ultimately protection of the salmon of the River Tweed – is overseen by a single body, the River Tweed Commission.
