Rhin-et-Moselle (German: Rhein-und-Mosel) is the name of a département of the First French Empire in present Germany. It is named after the rivers Rhine and Moselle. It was formed in 1798, when the left bank of the Rhine was annexed by France. Until the French occupation, its territory was divided between the Archbishopric of Cologne, the Archbishopric of Trier, and the Electorate of the Palatinate. Its territory is part of the present German states of Rhineland-Palatinate and North Rhine-Westphalia. Its capital was Coblenz. The département was subdivided into the following arrondissements and cantons:
