Lohr is a right tributary of the Main in Germany. Although its origins lie in the Main-Kinzig district of Hessen, most of the course of the Lohr is in the Main-Spessart district of Bavaria. Including its source river Lohrbach, it is 23.0 km long.
The Lohr is created by the confluence of the Flörsbach (right) and the Lohrbach (left). Around 1 km below the confluence, the Lohr enters Bavaria. It then flows south to Frammersbach, southeast to Partenstein and continues to Lohr am Main where it discharges into the Main.
