Francis I or Franz I. Graf zu Erbach-Erbach (Erbach im Odenwald, 29 October 1754 – Erbach 8 March 1823) was a German nobleman and art collector.
From 1769 to 1773, he studied politics and history in Lausanne, Strasbourg, and Paris. He also traveled extensively to London, Brussels, Den Haag, Berlin, Dresden, and Italy. While he was in Rome, he met several people that would become influential in his life, among them Ennio Quirino Visconti and Johann Friedrich Reiffenstein.
As the Count of Erbach, he paid special attention to agriculture, trade, and transportation. Through the influences of Reiffenstein and Visconti, Francis started his own art collection. This collection is now housed by the Erbach Palace. Francis dedicated his completed art catalogue to Reiffenstein. He was also the pioneer of ivory carving in Erbach, and his ivory collection now belongs to the German Ivory Museum Erbach.
