Conrad Buno (–1671), was a German copperplate engraver, cartographer and publisher at the court of Wolfenbüttel (Guelpherbytum) and brother of Johann Buno (1617–1697), the theologian and pedagogue from Lüneburg.
Conrad Buno prepared a set of maps for the 1641 Brunswick-Lüneburg edition of Philipp Cluver's famous Introductio in Universam Geographicam, an atlas with maps of Africa, America, Asia and the World, and text written by Johann Buno.
