Mosbach (German: [ˈmoːsˌbax] ⓘ; South Franconian: Mossbach) is a town in the north of Baden-Württemberg, Germany.

It is the seat of the Neckar-Odenwald district and has a population of approximately 25,000 distributed in six boroughs: Mosbach Town, Lohrbach, Neckarelz, Diedesheim, Sattelbach and Reichenbuch.

Mosbach is located about 35 km east of Heidelberg, south of the Odenwald mountains at a height of 134-354m at the confluence of the Neckar and the Elz.

With the division of the lands of King Rupert in 1410, Mosbach became the capital of a small principality known as Palatinate-Mosbach as the inheritance for his son Otto I.

In World War II, the Mosbach area was the location of a Daimler-Benz[4] underground airplane engine factory,[4][5] codenamed "Goldfisch".
