Ortenberg (German: [ˈɔʁtn̩bɛʁk] ⓘ; Low Alemannic: Ordäberig) is a municipality in the district of Ortenaukreis, Baden-Württemberg.

Ortenberg is located in the foothills of the Black Forest, on the edge of the Kinzig valley and on the border of the Upper Rhine Plain.

The castle-like construction, as it stands today, was planned by the German architect Friedrich Eisenlohr and built between 1838 and 1843 by Gabriel Leonhard von Beckholtz, a livonian merchant.

St. Bartholomew parish church was constructed by Hans Voß in a style similar to Weinbrenner's architecture.

Even though Ortenberg is located on Black Forest Railway, which leads from Offenburg to Singen, the train station has been out of use since the 1980s.
