Nighthawks is a 1942 oil on canvas painting by Edward Hopper that portrays four people in a downtown diner late at night as viewed through the diner's large glass window. The light coming from the diner illuminates a darkened and deserted urban streetscape. It has been described as Hopper's best-known work and is one of the most recognizable paintings in American art. Within months of its completion, it was sold to the Art Institute of Chicago on May 13, 1942, for $3,000.
