Außerfern (German pronunciation: [ˈaʊ̯sɐfɛʁn] ⓘ) refers to the district of Reutte in the Austrian federal state of Tyrol.
At the end of the 13th century it became part of the County of Tyrol through the imperial agreement (Reichseinigung) of Duke Meinhard, however the Außerfern's close economic and cultural relationships with the Allgäu region remained.
Linguistically the region is dominated by a mixed form of the Alemannic and Austro-Bavarian dialects.
Tourism is an important source of income, because the rather barren and high terrain is difficult to cultivate.
In addition, industry and trade play a role, especially in the central Lech valley and the Reutte Basin.
