Lunch atop a Skyscraper is a black-and-white photograph taken on September 20, 1932, of eleven ironworkers sitting on a steel beam 850 feet (260 meters) above the ground on the sixty-ninth floor of the RCA Building in Manhattan, New York City. It was arranged as a publicity stunt, part of a campaign promoting the skyscraper. The photograph was first published in October 1932 during the construction of Rockefeller Center. In 2016 it was acquired by the Visual China Group.

The image is often misattributed to Lewis Hine; the identity of the photographer remains unknown. Evidence emerged indicating it may have been taken by Charles C. Ebbets, but it was later found that other photographers had been present at the shoot as well. Many claims have been made regarding the identities of the men in the image, though only a few have been definitively identified. Ken Johnston, manager of the historic collections of Corbis, called the image "a piece of American history".
