Salm-Reifferscheid-Dyck was a small County of the Holy Roman Empire. Its territory was the area around Dyck (south-east of Mönchengladbach) in present North Rhine-Westphalia, Germany. Salm-Reifferscheid-Dyck was a partition of Salm-Reifferscheid, and was annexed by the First French Empire in the French Revolutionary Wars, in 1811. The county was mediatised to Kingdom of Prussia in 1813, of which Salm-Reifferscheid-Dyck became a princely title three years later. When the committal line died out, in 1888, the style was assumed by the princes of Salm-Reifferscheid-Krautheim.
