Au is a district in the south eastern plain tract of the German city of Munich in Bavaria.
Au extends from the Deutsches Museum in the north and along the Isar up to Wittelsbacherbrücke (Wittelsbacher Bridge) in the south.
In the centre of the area the Auer Dult takes place three times a year on the Mariahilfplatz, which is the largest annual market in Munich.
Bordering boroughs of the city are Ludwigsvorstadt-Isarvorstadt and Altstadt-Lehel on the western side of the Isar, Untergiesing-Harlaching in the south and Giesing in the south-east.
Hans-Georg Schwarzenbeck, a 1974 World Cup champion, has operated a stationery shop in Au for over 20 years.
