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.
Below, rivers are grouped by length, drainage area, orography and in alphabetical order.
Switzerland is drained into four directions: Witenwasserenstock mountain is the triple divide of the drainage basins between the Rhine, Rhône and Po.
Some rivers (e.g. Danube) do not flow through Switzerland themselves, but they are mentioned for having Swiss tributaries.
