Länder (Singular
Land) refers to one or any of:
- Colloquially used for States of Austria, the technically correct German language name for the federal states of Austria is Bundesländer, which is hardly used in Austria.
- Official (plural) title for the various Federal States of Germany under the German constitution, the Grundgesetz,
which explicitly names the states simply as Land (plural Länder), but which contrarily, colloquially are frequently referred to as Bundesländer.
