Lechrain is the name of an informally defined region of Germany extending southwards from Augsburg towards the foothills of the Alps along the Lech river, mainly on the east bank.

The name "Lechrain" includes the Old High German "rein", indicating a borderland, in this case between Bavaria and Swabia.

The main settlements are Kempten, Füssen, Kaufbeuren, Peiting, Schongau, Landsberg am Lech, Augsburg, Friedberg, Mering and Donauwörth.

[1] Before the Christian era the land was occupied by Celts, then by Romans and later by Alemanni and Bavarians.

In the 19th century, when Augsburg and east Swabia were incorporated in Bavaria it lost its political meaning, but it retains a distinctive culture.
