  Ölbronn-Dürrn is a municipality in the Enz district of Baden-Württemberg, Germany.
  
  ## History
  
  Ölbronn was a property of Maulbronn Monastery until 1504, when it became a possession of the Duchy of Württemberg. Maulbronn's district, which Ölbronn was assigned to, was reorganized as Oberamt Maulbronn [de] on 18 March 1806. When the Oberamt was dissolved on 1 October 1938, Ölbronn was reassigned to Landkreis Vaihingen [de].
  
  Dürrn became a possession of the Margraviate of Baden in 1730 and was assigned to the Oberamt [de] of Pforzheim. The town remained in Pforzheim's jurisdiction through reorganizations in 1809, 1819, and on 1 October 1864, and again on 25 June 1939, when the district became Landkreis Pforzheim [de].
  
  On 1 January 1973, as part of the 1973 Baden-Württemberg district reform [de], Ölbronn and Dürrn were assigned to the newly created Enz district. The two townships merged into a single municipality, Ölbronn-Dürrn, on 1 July 1974.
