Bad König (German: [baːt ˈkøːnɪç] ⓘ) is a town and resort (Kurort) in the central Odenwald in the Odenwaldkreis (district) in Hesse, Germany, 29 km southeast of Darmstadt.

In Roman times, the name for this place was apparently Quintiacum, and Quinticha was the name under which Bad König had its first documentary mention between 820 and 822.

Because of the scenes of utter brutality in connection with Kristallnacht, most of them left town, especially as from 1939 they were no longer allowed to buy food.

[3] The municipal election held on 6 March 2016 yielded the following results: There are local deputies in the outlying centres of Etzen-Gesäß, Fürstengrund, Kimbach, Nieder-Kinzig, Ober-Kinzig and Zell.

The Odenwaldbahn (railway; RMV Lines 80, 81, 82 and 85) links Bad König, as well as the outlying centre of Zell, with the Neckar valley and also Frankfurt and Darmstadt.
