Rodgau is a town located in the Offenbach district within the Regierungsbezirk of Darmstadt in the state of Hesse, Germany. Situated southeast of Frankfurt am Main, it is part of the Frankfurt Rhine Main Region and holds the distinction of being the most populous municipality in the Offenbach district.
The town was officially established in 1979 when the greater community of Greater Rodgau was elevated to town status. This entity was formed in 1977 through a merger of five formerly self-administering communities as part of a municipal reform in Hesse. While the current administrative structure is relatively modern, the history of its constituent communities dates back as far as the 8th century.
