List of non-marine molluscs of Austria

The non-marine molluscs of Austria are a part of the fauna of Austria. Austria is land-locked and therefore it has no marine molluscs, only land and freshwater species. This list is based on the current Red List of Austrian molluscs.

There are 443 species of non-marine molluscs living in Austria. Of these, 426 species live in the wild, 60 of which are endemic to Austria. At least 17 gastropod species live only as hothouse aliens in greenhouses, aquaria and terraria. Another 4 non-indigenous species occur only in hot springs.
