Michael Clark Rockefeller (May 18, 1938 – declared dead 1964) was an American collector and ethnographer who disappeared in 1961 during an expedition in what is now South Papua, Indonesia. He was a member of the Rockefeller family, the youngest son of Nelson Rockefeller, who later became Vice President of the United States. His disappearance has been the subject of competing theories, including drowning and death after reaching shore.
