Landshut (Austro-Bavarian: Landshuad) is a city in Bavaria in the south-east of Germany, belonging to both Eastern and Southern Bavaria. Situated on the banks of the River Isar, Landshut is the capital of Lower Bavaria, one of the seven administrative regions of the Free State of Bavaria. It is also the seat of the surrounding district. With a population of more than 60,000, Landshut is the largest city in Lower Bavaria, followed by Passau and Straubing, as well as Eastern Bavaria's second biggest city after Regensburg.

Owing to its characteristic coat of arms, the city is also often called "Three Helmets City" (German: Dreihelmenstadt).

Due to its proximity and easy access to Munich and the Franz Josef Strauss International Airport, situated halfway between Munich and Landshut on the banks of the Isar, the city has East Bavaria's lowest unemployment rate (ca. 4.2% in October 2006), lower than the Bavarian average of ca. 5.8%.

Landshut lies in the centre of Lower Bavaria, and is part of the Alpine foothills. The River Isar runs through the city centre. Landshut is about 72 kilometres (45 mi) northeast of Munich.
