Jungholz (German pronunciation: [ˈjʊŋhɔlt͡s] ⓘ) is a village in the district of Reutte in the Austrian state of Tyrol that is only accessible via Germany.

Letters to Jungholz can be addressed with either a German or an Austrian postal code.

Two Austrian (Tyrolean, Reutte) and two German (Bavarian, Oberallgäu) municipalities meet at that point, starting with Jungholz and continuing clockwise: On 24 June 1342, Hermann Häselin, a farmer from Wertach in Germany, sold the area to Heinz Lochpyler, an Austrian taxman from nearby Tannheim.

[citation needed] Its customs union with Germany dates to a Treaty signed in 1868.

[4] In 1938 following the German takeover of Austria, Jungholz and the similarly isolated Kleinwalsertal were annexed to Gau Swabia in Bavaria, though returned to Austria after the end of WWII.
