List of alternative names for European rivers

All or almost all rivers in Europe have alternative names in different languages. Some rivers have also undergone name changes for political or other reasons. This article provides known alternative names for all major European rivers. It also includes alternative names of some lesser rivers that are important because of their location or history.

This article does not offer any opinion about what the "original", "official", "real", or "correct" name of any river is or was. Rivers are listed alphabetically by their current best-known name in English. The English version is followed by variants in other languages, in alphabetical order by name, and then by any historical variants and former names.

Foreign names that are the same as their English equivalents may be listed, to provide an answer to the question "What is that name in...?".
