Rhin-et-Moselle was a department of the First French Republic and First French Empire in present-day Germany. It was named after the rivers Rhine and Moselle. It was formed in 1797, 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 now part of the German states of Rhineland-Palatinate and North Rhine-Westphalia. Its capital was Koblenz.
