Henri Nannen (25 December 1913 in Emden – 13 October 1996 in Hanover) was a German journalist and art collector.

After a one-year book dealer apprenticeship he studied the history of art at the University of Munich.

Being large, well-built and fair haired, he corresponded to the racial ideals of the time in Germany.

This made him the speaker of the Olympic Oath during the 1936 event in Berlin – for Riefenstahl's film, but not in reality.

He was the founder of Gruner + Jahr publishing house and the news magazine Der Stern.
