Christoph von Graffenried, 1st Baron of Bernberg (15 November 1661 – 27 October 1743) was a Swiss nobleman and explorer who was one of the founders of New Bern, North Carolina. Born in Worb Castle in the Canton of Bern, he played a major role in the colonisation of North America by German and Swiss settlers. In c. 1716, von Graffenried published a memoir entitled Relation of My American Project, which recounted his life in both Switzerland and North America.
