# List of rivers of Switzerland

The following is a list of rivers of Switzerland (and tributaries thereof). Included rivers flow either entirely or partly through Switzerland or along its international borders. Swiss rivers belong to five drainage basins, i.e. of the Rhine, the Rhône, the Po, the Danube or the Adige. Of these, only the Rhine and Rhône flow through Switzerland (and also originate there). The waters therefore drain into either the North Sea, the Mediterranean Sea or the Black Sea.
Below, rivers are grouped by length, drainage area, orography and in alphabetical order. A list of border rivers is also given.

## Rivers by length

## Rivers by orography

Switzerland is drained into four directions:
* North Sea, via the Rhine.
* Mediterranean Sea:
** Gulf of Lion, via the Rhône.
** Adriatic Sea, via the Po and the Adige.
* Black Sea, via the Danube.

### Drainage basins

Witenwasserenstock mountain is the triple divide of the drainage basins between the Rhine, Rhône and Po. Lunghin Pass is the triple divide between the Rhine, Danube and Po.
Rivers that flow into other rivers are sorted by the proximity of their points of confluence to the sea (the lower in the list, the more upstream). Some rivers (e.g. Danube) do not flow through Switzerland themselves, but they are mentioned for having Swiss tributaries. They are given in italics. The five drainage basins are highlighted in bold.
