Diósd (German: Orasch), Hungary is a small town located between the larger cities of Budapest and Érd in the Budapest metropolitan area, Pest County. It best found by travelling on the road 7 (also known as Balatoni út), which crosses the commune. The motorway M0 runs at the very edge of Diósd.

Though many residents commute to work in the capital city of Budapest, the largest employers in the town are a manufacturing plant, named New MGM Zrt., that produces ball bearings and tapered roller bearing for worldwide OEM customers and dealers, an Interspar grocery store, and the International Christian School of Budapest[1], a school that serves missionary families, expatriates, and Hungarians.

Diósd has also a German name, called Orasch. The reason for this phenomenon is that after the Turkish invasion, the area was fully uninhabited. Swabians arrived from Southern Germany to repopulate the town and they were in majority there until the end of the second world war, when many of the Swabes were chased away.
