Der gerettete Alberich (Alberich Saved) is a concerto for percussion and orchestra by the American composer Christopher Rouse. The work was jointly commissioned by the London Symphony Orchestra, the Cleveland Orchestra, the Philadelphia Orchestra, and the Baltimore Symphony Orchestra. It was completed June 7, 1997, and premiered January 15, 1998 in Cleveland, Ohio with the Cleveland Orchestra under conductor Christoph von Dohnányi. The piece is dedicated to percussionist Evelyn Glennie, who performed the solo during the world premiere. Rouse composed the work as an informal musical sequel to Richard Wagner's four-opera cycle Der Ring des Nibelungen.
