The Diepholz Airfield Circuit was an auto racing circuit in the south-west of Diepholz, Germany. It was a temporary circuit on the Diepholz Air Base, a base which is still in use by the German Air Force today.
The full length of the runway was used as part of the circuit, with a fast double chicane and a straight start/finish, which included a temporary pit lane going down one side of the runway. There were no pit garages or permanent racing-related buildings on site.
Racing occurred at Diepholz in 1968 due to a lack of permanent circuits in Germany. Used mainly for touring car racing, Diepholz was a regular venue on the calendar for the DTM series. When the DTM, then known as the FIA International Touring Car Championship, collapsed at the end of 1996, the circuit had little use. In 1997 and 1998, the circuit hosted races for Formula König, Formula Renault 2.0 Germany, and Porsche Carrera Cup Germany. Since then, the circuit has not hosted any races.
