Dietzenbach (German pronunciation: [ˈdiːtsn̩ˌbax] ⓘ) is the seat of Offenbach district in the Regierungsbezirk of Darmstadt in Hesse, Germany and lies roughly 12 km southeast of Frankfurt am Main on the waterstream Bieber.

Lying in the Upper Rhine Plain, the climate of the Offenbach (district) is temperate and influenced through southwestern trade winds.

In Dietzenbach, the average high temperature of the warmest month is 26 °C, in the central valleys they are three degrees Celsius higher.

The town of Dietzenbach is made up of a number of Stadtteile, although not all places listed here have this official designation.

Before this, the most prominent feature was a shopping centre with a big supermarket, filling station and carpark, which the locals over time came to see as an eyesore for its rather unappealing 1970s architecture and the company's neglect of the building.

After the old toom Markt closed in mid-2005, the whole building complex was torn down in autumn 2006 to make way for a new shopping centre.

The foundation stone was laid on 4 December 2006, and on 29 November 2007, the shopping centre opened, and was given the name Rathaus-Center.

At the upper end of the neighbourhood are found, besides a sporting ground, a restaurant with a viewing terrace and the lookout tower built for the Hessentag state festival, from which it is possible to see Frankfurt.

Originally planned as an upscale neighbourhood, social problems and the crime arising therefrom have brought the town and the surrounding area greater challenges than ever.

[3] The later forsaken settlements of Ippingshausen and Richolshausen lay within what are now Dietzenbach's limits in the Early Middle Ages.

When the Counts of Hanau died out in 1736, the Landgraves Hesse-Darmstadt and of Hesse-Kassel fought over who had the right to be Dietzenbach's lords.

However, it was only officially allowed to use the designation Kreisstadt (“District Seat”) beginning in March 2003 as the result of a dispute with the neighbouring town of Rodgau, which had demanded this status on the grounds that it had a greater population.

[5] The elections in March 2016 showed the following results:[6] Dietzenbach has an Ausländerbeirat – a foreigners’ advisory council – made up of 19 persons representing various nationalities with people from Turkey, Morocco, Italy, Pakistan, Afghanistan, India, Chile and Croatia.

The town's current arms were determined by its community councillors in 1957 and approved by the then Hessian Interior Minister Schneider.
