The Wheel of Mainz or Mainzer Rad, in German, was the coat of arms of the Archbishopric of Mainz and thus also of the Electorate of Mainz (Kurmainz), in Rhineland-Palatinate, Germany. It consists of a silver wheel with six spokes on a red background. The wheel can also be found in stonemasons' carvings (e.g. landmarks) and similar objects. Currently, the City of Mainz uses a double wheel connected by a silver cross.
