"Lunch atop a Skyscraper" (New York Construction Workers Lunching on a Crossbeam) is a photograph taken atop the steelwork of 30 Rockefeller Plaza, during the construction of the Rockefeller Center, in Manhattan, New York City, United States.

The photograph depicts eleven men eating lunch, seated on a girder with their feet dangling 840 feet (260 meters) above the New York City streets. The photograph was taken on September 20, 1932, on the 69th floor of the RCA Building during the last months of construction. According to archivists, the photograph was in fact prearranged. Although the photograph shows real ironworkers, it is believed that the moment was staged by Rockefeller Center to promote its new skyscraper. Other photographs taken on the same day show some of the workers throwing a football and pretending to sleep on the girder. The photo appeared in the Sunday photo supplement of the "New York Herald Tribune" on October 2, 1932.
