Rauschenberg lies at the southern edge of the Burgwald, a low mountain range, near Marburg and Kirchhain.
Rauschenberg borders in the north on the town of Rosenthal (Waldeck-Frankenberg) as well as on the communities of Wohratal (Marburg-Biedenkopf) and Gilserberg (Schwalm-Eder-Kreis), in the east on the town of Stadtallendorf, in the south on the town of Kirchhain, in the southwest on the community of Cölbe, and in the west on the town of Wetter (all in Marburg-Biedenkopf).
Rauschenberg consists of the following centres: Albshausen, Bracht, Ernsthausen, Josbach, Rauschenberg, Schwabendorf and Wolfskaute.
Even as far back as 1000, a castle was built in what is now Rauschenberg. After a fire about 1250, almost the whole settlement was destroyed. Shortly after Rauschenberg was founded by the Counts of Ziegenhain, it was granted town rights. When the "von Ziegenhain" family died out in 1450, the castle and the town fell to the House of Hesse. In this time, the castle was expanded and made into a hunting lodge.
During the Thirty Years' War, Rauschenberg was mostly destroyed and thoroughly plundered by Swedish troops. Ever since the castle was blown up at a Kassel colonel's behest two years before the war ended, there has been nothing left of it but a ruin.

Rauschenberg's civic coat of arms might be described thus: Party per fess; above, in sable a six-pointed star argent; below in Or. It matches the arms used by the town's old overlords, the Counts of Ziegenhain. The Hessisches Ortswappenbuch (1956, published by Verlag C. A. Starke, Limburg), a work about Hessian civic arms, shows an eight-pointed star in a modification of the Counts' coat of arms, as indeed does the International Civic Heraldry website.
