Obernheim is a municipality of the Zollernalbkreis district of Baden-Württemberg, Germany.

Obernheim became a possession of the Kingdom of Württemberg in 1805 and was assigned to Oberamt Balingen [de]. Five years later, in 1810, it was reassigned to Oberamt Spaichingen [de], which was merged into Landkreis Balingen [de] in 1938. Obernheim grew and industrialized after the Second World War, first expanding in the 1950s to the north-east and west, and then in the 1970s to the north once more. As part of the 1973 Baden-Württemberg district reform [de], Landkreis Balingen was dissolved and Obernheim was assigned to the newly created Zollernalb district. There was further municipal growth to the northeast in the 1980s and 1990s.^[3]

Elevation above sea level ranges in the municipality from a high of 988 meters (3,241 ft) Normalnull (NN) to a low of 751 meters (2,464 ft) NN.^[3]

Obernheim's coat of arms is a field of white crossed by a single blue bar. This pattern was adapted from the personal blazon of Johann von Obernheim, a local 14th century nobleman, and was approved for official use by the provisional post-WWII Württemberg-Hohenzollern government on 27 October 1950. A corresponding flag was issued on 15 January 1982.^[3]

Obernheim was connected to the Heuberg Railway until its station was closed in 1996. Local public transportation is provided by the Verkehrsverbund Neckar-Alb-Donau [de].^[3]
