This list of rivers in Scotland is organised geographically, taken anti-clockwise, from Berwick-upon-Tweed. Tributaries are listed down the page in an upstream direction. (L) indicates a left-bank tributary and (R) indicates a right-bank tributary whilst (Ls) and (Rs) indicate left and right forks where a named river is formed from two differently named rivers.

For simplicity, they are divided here by the coastal section in which the mouth of the river can be found. Those on Scottish islands can be found in a section at the end. For Scottish estuaries, please see under firths and sea lochs.

The Scots have many words for watercourses.

• A "Water" (Lallans: "Watter", Scots Gaelic, "Uisge") is a smaller river, e.g. Ugie Water, Water of Leith etc. Many Scottish rivers incorporate the name "Water" traditionally.
• A "burn", Scots Gaelic: "allt" (anglicised as "Ault/alt"), used for smaller rivers and larger streams, also once widely used in England, now mostly in placenames especially the north, and sometimes spelled "bourne", e.g. Bournemouth and Ashbourne. In Scotland examples include Coalburn, Bannockburn, Aultmore.
• Abhainn in Gaelic meaning river, which is anglicised as Avon. There is also a similar Brythonic cognate. This sometimes leads to curious 'double' namings of rivers by Anglo-Saxon speakers, such as River Avon and River Afton (literally "River River").

Flowing into the North Sea between Berwick-upon-Tweed and Kincardine (East Coast)

Various measurements are provided for the lengths of Scottish rivers. The table below distinguishes between the river alone and the river plus tidal waters, which many sources use. In all cases the distance is for the longest distance through the catchment area not just the distance of that portion of it which the named river covers excluding upstream tributaries.

The major rivers of Scotland, in order of catchment,^[2] are:

1. River Tay c. 2,000 square miles (5,200 km²)
2. River Tweed 1,500 square miles (3,900 km²)
3. River Spey 1,097 square miles (2,840 km²)
