Lower Bavaria (German: Niederbayern) is one of the seven administrative regions of Bavaria, Germany, located in the east of the state. It is subdivided into three regions (Planungsverband)—Landshut, Passau and Donau-Wald. Recent election results mark it as the most conservative part of Germany, generally giving huge margins to the CSU. This part of Bavaria includes the Bavarian Forest, a well-known tourist destination in Germany, and the Lower Bavarian Upland.

Rottal-Inn is a Kreis (district) in the southeastern part of Bavaria, Germany. Neighboring districts are (from the south clockwise) Altötting, Mühldorf, Landshut, Dingolfing-Landau and Passau. To the southeast is the Austrian state Upper Austria(Braunau).
The main rivers in the district are the Inn and its tributary, the Rott.
